Abstract

MES features on the IBM eServer zSeries 890 (z890), previously announced as withdrawn as of June 30, 2008, are now extended to September 30, 2008. This withdrawal date also applies to the z890 field-installed features and conversions which are delivered solely through a modification to the machine's Licensed Internal Code (LIC).

IBM will also no longer accept any new Capacity BackUp (CBU) contracts or on-demand upgrade orders (Customer Initiated Upgrade (CIU) or On/Off Capacity on Demand (On/Off CoD)) for z890 machines as of October 1, 2008.

The 2086 IBM eServer z890 represents the continuation of a generation scalable servers introduced with the IBM eServer z990. Using z/Architecture(TM) and the latest zSeries building blocks and virtualization technology, the z890 extends key zSeries platform characteristics of reliability, availability, scalability, clustering, and quality of service to respond to the ever-changing business climate. It offers a processor that delivers extensive growth options and excellent price/performance for those customers requiring a lower-capacity entry point than offered with the z990.

The IBM eServer z890 is designed to help enable your businesses to be resilient in the unpredictable on demand world. With a single model and a wide range of capacity settings, the newest member of the zSeries family delivers significantly improved granularity and enriched functions over its predecessor, the z800 -- it can provide up to almost twice the processing power, up to 123% greater total system capacity, and significantly increased I/O capacity. The z890 can support double the number of Logical Partitions (LPARs) and the Logical Channel SubSystem (LCSS) feature introduced on z990, which facilitates horizontal growth, and is introducing the IBM eServer zSeries Application Assist Processor (zAAP), which provides an attractively priced Java execution environment.

To address the growing complexity of fiber optic connectivity in the Information Technology (IT) infrastructure, IBM Networking Services will continue to offer scalable fiber optic cabling services to help satisfy e-business infrastructure requirements at both the product level and the enterprise level.

Description

A z890 Technology Overview

z890 - the platform "right-sized" for server consolidation

The design of z890 represents the continuation of a major change for the latest zSeries (TM) technologies which were introduced with IBM eServer zSeries 990. IBM eServer zSeries 890, like zSeries 990, contains a new superscalar microprocessor architecture exploiting the CMOS9S-SOI technology and improving uniprocessor performance. z890 is an air- cooled, single-frame, single-book variant of the z990 platform. The capability for a significant capacity increase versus z800 has been achieved with the availability of the following on z890:

  • Up to 32 gigabytes of memory -- 8 GB, 16 GB, 24 GB, 32 GB.

  • Up to 16 gigabytes of bandwidth for data communication between I/O and memory via up to eight Self-Timed Interconnect (STI) host buses.

  • One I/O cage with 28 I/O slots (16 on the smallest sub-uniprocessor equipped capacity setting).

  • A new Channel SubSystem (CSS). Two Logical Channel SubSystems (LCSSs) can exist for horizontal growth, supporting up to 256 CHPIDs per LCSS for a total of 512 CHPIDs per server.

  • Double the number of Logical Partitions (LPARs) -- now 30 LPARs (15 on the smallest sub-uniprocessor equipped capacity setting).

  • Increased channel maximums for ESCON (R), FICON (TM) Express, ISC-3, and OSA-Express (except on the smallest sub-uniprocessor equipped capacity setting).

  • Quadruple the number of HiperSockets -- now 16 internal LANs.

  • Three cryptographic options:
    • New CP Assist for Cryptographic Function (CPACF) on every CP.
    • New PCIX Cryptographic Coprocessor (PCIXCC) feature.
    • PCI Cryptographic Accelerator (PCICA) feature.

  • Integrated Cluster Bus-4 (ICB-4), up to two times faster than an ICB-3.

  • Coupling Facility Control Code (CFCC) Level 13, supporting:
    • CFCC Enhanced Patch Apply.
    • DB2 Performance for cast-out processing.

  • Five Processor Units (PUs):
    • One model.
    • Twenty-eight unique capacity settings, offering increased granularity.
    • Up to four Central Processors (CPs). One mandatory System Assist Processor (SAP). Refer to the table following.

  • IBM eServer zSeries Application Assist Processor (zAAP).

  • Internal Battery Feature (IBF).

A Processor Unit (PU) is the generic term for the z/Architecture processor on the MultiChip Module (MCM) that can be characterized as a:

  • Central Processor (CP) to be used by the operating system
  • Internal Coupling Facility (ICF) to be used by the Coupling Facility Control Code (CFCC)
  • Integrated Facility for Linux (IFL)
  • IBM eServer zSeries Application Assist Processor (zAAP)

With z890 at least one CP, ICF, or IFL must be purchased and activated. For each zAAP engine installed there must be a corresponding CP engine permanently purchased and installed. PUs can be characterized in single-PU increments and are orderable by feature code.

Functions and Features: The IBM eServer zSeries 890

  • z890 consists of one Model (A04) and 28 capacity settings.
  • All configurations of z890 contain the same number of physical Processor Units (5), however, the customer is only licensed to use the Licensed Internal Code (LIC) to support the amount of capacity actually purchased.
  • Each configuration has one mandatory SAP and must contain at least one CP, IFL, or ICF engine. For each zAAP engine installed there must be a corresponding CP engine permanently purchased and installed.
  • A z890 can be configured with all IFL or all ICF engines.
  • Any remaining PUs (subject to configuration rules and execution of appropriate terms and conditions, as applicable) may be assigned to optional functions such as ICFs, IFLs, zAAPs, On/Off Capacity on Demand (On/Off CoD), or Capacity BackUp Upgrade (CBU), or they may be assigned as spares.
  • The total number of SAP, CP, ICF, IFL, zAAP, spare, On/Off CoD, or CBU engines cannot exceed five (the total number of PUs available).
  • CBU applies to whole zSeries CP engine additions only and only to the largest capacity configuration (full engine).
  • CBU does not apply to changes in capacity setting and does not apply to IFLs, ICFs, SAPs, zAAPs, or memory
  • CBU is always a temporary capacity upgrade.
  • On/Off CoD is a Licensed Internal Code (LIC) enabled temporary capacity upgrade with a prerequisite of enablement feature codes 9898 and 9896. Downgrades from this temporary capacity are to the original capacity setting only.
  • With On/Off CoD, while capacity upgrades to the processor itself are concurrent, some operating system software may not be able to take advantage of changes in capacity without performing an Initial Programming Load (IPL).
  • On/Off CoD activation is mutually exclusive with CBU activation. Both On/Off CoD and CBU can reside on the server, but only one can be activated at a time.
  • On/Off CoD can be activated and the CBU feature is not removed.

The following table describes the content of the z890 Model A04, including the number of:

  • Processor Units (PUs)
  • System Assist Processors (SAPs)
  • Central Processors (CPs)
  • Optional Internal Coupling Facilities (ICFs)
  • Optional Integrated Facility for Linux features (IFLs)
  • Optional IBM eServer zSeries Application Assist Processor features (zAAPs)
  • Spare Processor Units (Spares)
  • Available engines for On/Off Capacity on Demand (On/Off CoD)
  • Available engines for Capacity Back Upgrade (CBU)

  • z890 to z890 upgrades: Any to any.
  • z890 to z990 upgrades: There will be limited upgrade paths from z890 Model A04 to z990 Model A08 only. For details contact your IBM representative or an IBM Business Partner.

Refer to the Customer Initiated Upgrade Capacity section for information on permanent and temporary capacity.

Server consolidation facilitated

With the expanded capacity of z890 over z800, and the Channel SubSystem, there is a significant increase in server scalability, facilitating consolidation of multiple servers into one z890.

With z/OS V1.4 z990 Exploitation Support feature, you will be able to install more operating system images and up to a total of 512 CHPIDs (up to 256 CHPIDs maximum per operating system), allowing each z890 except the smallest sub-uniprocessor equipped capacity setting to access more channels, Coupling Links, and LANs -- ESCON (up to 420 channels), FICON Express (up to 40 channels), ISC-3 (up to 48 links), and OSA-Express (up to 40 ports).

The Performance Advantage

Performance estimates with z/OS V1.4

IBM's Large Systems Performance Reference method provides comprehensive z/Architecture(TM) processor capacity data for different configurations of Central Processor Units across a wide variety of system control program and workload environments.

Compared to some of the 2066 z800 servers, the z890 server is expected to offer the following performance advantage:

The above performance estimates are Internal Throughput Rate Ratios (ITRR) based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. For more detailed performance information, consult the Large Systems Performance Reference (LSPR). Customers interested in LSPR should contact their IBM representative.

The proper IBM zSeries workload tuning and capacity sizing tools should be utilized if the customer needs assistance from IBM to help determine the appropriate capacity to purchase.

Performance Assists for Linux and z/VM

z890 adapter interruptions for Linux and z/VM

Reducing overhead for CHPID types FCP and OSD:

The z890, Linux on zSeries, and z/VM V4.4, and later, work together to help enable performance improvements by exploiting extensions to the Queued Direct Input/Output (QDIO) architecture when running Linux on zSeries under this configuration.

Adapter interruptions, first added to z/Architecture with HiperSockets, is designed to help provide an efficient, high-performance technique for I/O interruptions to reduce path lengths and overhead in both the host operating system and the adapter - FICON Express when using the CHPID type FCP, and OSA-Express when using the CHPID type OSD.

In extending the use of adapter interruptions to FICON Express CHPID type FCP and OSA-Express CHPID type OSD, IBM has reduced the programming overhead to process a traditional I/O interruption. This can benefit OSA-Express TCP/IP support in both Linux on zSeries and z/VM, FCP support in Linux on zSeries, and Linux on VSE/ESA V2.7 (OSD CHPID Type only).

Support for adapter interruptions is designed to improve performance of VSE/ESA V2.7 guest operating systems using TCP/IP for VSE/ESA when VSE/ESA V2.7 is running as guest system under z/VM V4.4 (for OSA-Express CHPID type OSD only).

Adapter interruptions apply to all of the FICON Express features available on z890 when in FCP mode (CHPID type FCP). FCP supports attachment of SCSI disks via Directors in a Linux on zSeries environment. Adapter interruptions apply to all of the OSA-Express features available on z890 when in QDIO mode (CHPID type OSD). This support is exclusive on zSeries to z890 and z990.

Note: HiperSockets supported adapter interruptions at introduction.

The Queued Direct Input/Output (QDIO) architecture is utilized by:

  • FICON Express when configured to support SCSI disks using the Fibre Channel Protocol (CHPID type FCP) in a Linux on zSeries environment

  • HiperSockets (CHPID type IQD) for IP communication between LPARs, between an LPAR and a VM guest, or between VM guests

  • All of the OSA-Express features in QDIO mode (CHPID type OSD)

QDIO continues to be the preferred architecture on zSeries for high-speed communication, helping to reduce host interruptions and improve response time.

Performance assist for V=V guests in the z/VM environment

Passthrough of adapter interruptions for CHPID types FCP, IQD, and OSD: z890's support of virtual machine technology has been enhanced to include a performance assist for virtualization of adapter interruptions. This performance assist is available to V=V guests (pageable guests) that support QDIO with z/VM V4.4 (with PTFs), and later. The deployment of adapter interruptions is designed to help improve efficiency and performance by reducing overhead.

The performance assist for V=V guests is a passthrough architecture that reduces host programming overhead by avoiding the need to stop guest processing when adapter interruptions are presented. Without the assist, the z/VM control program must intercede to process and route the adapter interruptions.

The performance assist can help improve Linux on zSeries performance under z/VM by allowing guest I/O - FICON (CHPID type FCP), HiperSockets (CHPID type IQD), and OSA-Express (CHPID type OSD) - to be handled with minimal z/VM overhead through direct presentation of adapter interruptions by the server to a pageable guest, helping to boost I/O performance.

This support is available with z/VM V4.4, and later. z/VM V4.4 requires PTFs to support this assist. Refer to the z/VM subset of the 2086DEVICE Preventive Service Planning (PSP) bucket prior to installing a z890.

IBM eServer zSeries Application Assist Processor The assist feature, IBM zSeries Application Assist Processor (zAAP) (#6520), will be available on z890 and z990. zAAP is an attractively priced specialized processor unit that provides an economical Java execution environment for customers who desire the traditional Qualities of Service and the integration advantages of the zSeries platform.

When configured with central processors (CPs) within logical partitions (LPARs) running z/OS or z/OS.e, zAAPs may help increase CP productivity and may contribute to lowering the overall cost of computing for z/OS and z/OS.e Java technology-based applications. zAAPs are designed to operate asynchronously with the CPs to execute Java programming under control of the IBM Java Virtual Machine (JVM). This can help reduce the demands and capacity requirements on CPs which may then be available for reallocation to other zSeries workloads.

The IBM JVM processing cycles can be executed on the configured zAAPs with no anticipated modifications to the Java applications. Execution of the JVM processing cycles on a zAAP is a function of the Software Developer's Kit (SDK) 1.4.1 for zSeries, z/OS and z/OS.e V1.6, and Processor Resource/Systems Manager (PR/SM).

The amount of CP savings will vary based on the amount of Java application code executed by zAAPs. This is dependent upon the amount of Java cycles used by the relevant applications and on the zAAP execution mode selected by the customer.

Execution of the Java applications on zAAPs (#6520), within the same z/OS or z/OS.e SMP LPAR as their associated database subsystems, can also help simplify the server infrastructures and improve operational efficiencies. For example, use of zAAPs could reduce the number of TCP/IP stacks, firewalls, and physical interconnections (and their associated processing latencies) that might otherwise be required when the application servers and their database servers are deployed on separate physical server platforms.

IBM does not impose software charges on zAAP capacity. Additional IBM software charges will apply when additional CP capacity is used.

Customers are encouraged to contact their specific Independent Software Vendors (ISVs) or Utilities Software Vendors (USVs) directly to determine if their charges will be affected.

Extended Translation Facility

The Extended Translation Facility adds 10 new instructions to the zSeries instruction set. These instructions may enhance performance for data conversion operations done supporting data encoded in Unicode, improving the ability to efficiently support applications enabled for Unicode and/or Globalization. The instructions add hardware support for conversions to and from the various Universal Character Set (UCS) Transformation Formats (UTF) encodings used to support Unicode.

These formats for encoding data are used in a number of important technologies emerging in the Web Services, Grid, and on demand environments, such as XML and SOAP as well as being supported in DB2 for data storage. The initial programming support for these instructions are intended to be provided in High Level Assembler.

z/OS.e and zSeries 890 for application workloads z/OS. e is unique for z890 and z800 -- a specially priced offering of z/OS, providing the z/OS qualities of service to help you deploy new applications. z/OS.e has the same migration, fallback, and coexistence as z/OS, allowing you to leverage existing skills and investments. z/OS.e must execute in z/Architecture (64-bit) mode.

Breaking the Barrier - The Channel SubSystem

Breaking the barrier of 256 CHPIDs

With the introduction of this server structure and all of its scalability benefits, it is essential that the Channel SubSystem (CSS) also be scalable and permit "horizontal" growth. This is facilitated by allowing more than one Logical Channel SubSystem (LCSS) on a single z890. Consistent with this premise, IBM is introducing increased connectivity by offering the following channel/port maximums. For reference, the new maximums are contrasted with the z800 maximums.

                                        z890
                                       Capacity
             Channel           z890    Setting 110   z800
              Type            Maximum  Maximum      Maximum
          - - - - - - -       - - - -  - - - - -    - - - -
          ESCON                 420(1)    240         240
          FICON Express          40(1)     32          32
          ISC-3(2)               48        48          24
          OSA-Express            40(1)     24          24
 

Note: (1) Except on the smallest sub-uniprocessor equipped capacity setting

Note: (2) A maximum of 32 ISC-3s can be defined in compatibility mode.

The Channel SubSystem structure offers the following:

  • Two Logical Channel SubSystems (LCSSs)

    • Each LCSS can have up to 256 CHPIDs defined.

    • Each LCSS can be configured with one to 15 Logical Partitions (LPARs).
      • Cannot exceed 30 LPARs per server (15 LPARs on the smallest sub-uniprocessor equipped capacity setting)

z/OS V1.4 z990 Exploitation Support feature is required for z/OS to run in more than a single LCSS. Without z/OS V1.4 z990 Exploitation Support feature, z/OS may only execute in LCSS0. z/VM V3.1, V4.3, and later, may execute in LCSS0 and LCSS1. However, when using z/VM V3.1 and V4.3 compatibility support, dynamic I/O configuration is supported in LCSS0 only.

Note: There is no change to the operating system maximums. One operating system image continues to support up to a maximum of 256 Channel Path Identifiers (CHPIDs).

The I/O SubSystem (IOSS) continues to be viewed as a single Input/Output Configuration Data Set (IOCDS) across the entire server with up to two LCSSs. Only one Hardware System Area (HSA) is used.

In the past, a two-digit identifier, a CHPID, was associated with a physical I/O connection. Now a three-digit Physical Channel Identifier (PCHID) is being introduced to accommodate the mapping of 512 CHPIDs to two LCSSs with up to 256 CHPIDs each. CHPIDs continue to exist and will be associated with PCHIDs.

As a result of the introduction of PCHIDs, a CHPID Mapping Tool (CMT) is being introduced and the CHPID report from the IBM Configurator For e-business (eConfig) is replaced by a PCHID report. CMT is available from Resource Link(TM) as a standalone PC-based program.

Refer to z890 documentation for additional information on this mapping tool, CHPIDs, and PCHIDs.

Dynamic I/O configuration support allows channel paths, control units, and devices to be dynamically added, changed, and deleted in multiple LCSSs.

When z/VM is the controlling LPAR, z/VM's dynamic I/O support is designed to handle all of the elements of the multiple Channel SubSystem facility for dynamic I/O configuration changes. To dynamically change the I/O configuration one of two techniques can be employed:

  • z/VM Control Program (CP) suite of interactive dynamic I/O commands
  • HCM/HCD -Configuration management tools

Spanned channel support

Transparent sharing of internal and external channels across LCSSs: When Logical Channel SubSystems (LCSSs) were introduced on z990, transparent sharing of internal channels was introduced -- sharing of HiperSockets and Internal Coupling Channels (ICs) between separate LCSSs. Support on zSeries 890 includes support for sharing of internal channels (HiperSockets and ICs), as well as sharing of external channels -- FICON Express, ICB-3, ICB-4, ISC-3, and OSA-Express features; they can all now be configured as Multiple Image Facility (MIF) spanning channels, allowing sharing of channel resources across Logical Partitions (LPARs).

Spanned channels can be shared among LPARs across LCSSs. FICON Express, HiperSockets, ICs, ICB-3, ICB-4, ISC-3, and OSA-Express can be configured to multiple channel subsystems and be transparently shared by any or all of the configured LPARs without regard to the LCSS to which the LPAR is configured.

The following may be spanned:

Internal Spanned Channels

Feature            CHPID type
------------       ----------
HiperSockets       IQD
IC                 ICP
 

External Spanned Channels

Feature            CHPID type
-------------      ----------------------------------------
FICON Express      FC, FCP
ICB-3              CBP, Peer
ICB-4              CBP, Peer
ISC-3              CFS, Coupling Sender, Compatibility mode
ISC-3              CFP, Peer
OSA-Express        OSC, OSD, OSE
 

Note: While the PCICA and PCIXCC features do not have CHPID types and are not identified as spanned channels, all LPARs in all LCSSs have access to the PCICA feature, up to 30 LPARs per feature. All LPARs in all LCSSs have access to the PCIXCC feature, up to 16 LPARs per feature. Under certain circumstances earlier releases of the z/OS operating system are supported. Refer to the publication "z/OS Migration" (GA22-7499) for more details. An update to this publication, discussing the external spanned channel types, is planned to be available in the z/OS V1.6 timeframe.

Another breakthrough - more subchannels for increased connectivity:

With two Logical Channel SubSystems come more subchannels. There has been a 63k subchannel limitation. Since there was one CSS, there was a maximum of 63k subchannels. With two Logical Channel SubSystems, each LCSS can have its own set of up to 63k subchannels.

With two Logical Channel SubSystems you can have:

  • Up to a maximum of 63k devices/subchannels per LCSS
  • Up to a maximum of 126k devices for two LCSSs
    • Two LCSSs x 63k subchannels for each LCSS

Each LPAR can access the 63k devices in its assigned LCSS. This capability helps to relieve the I/O device configuration constraints experienced by large server configurations.

A Giant Step - Support for 30 Logical Partitions

Doubling the number of LPARs supported: Processor Resource/Systems Manager(TM) (PR/SM)(TM), introduced in February, 1988, allowed IBM S/390 and now zSeries to be logically partitioned. Prior to that time, IBM mainframes could only be physically partitioned. When IBM introduced PR/SM and Logical Partitions (LPARs), initially four LPARs were supported, growing to 10 LPARs in June, 1992, followed by 15 LPARs in June, 1997, and finally 30 LPARs at introduction of zSeries 990. zSeries 890 supports 30 LPARs, 15 LPARs per LCSS, except on the smallest sub-uniprocessor equipped capacity setting which supports a total of 15 LPARs.

Dynamic add/delete of a logical partition name

The ability to add meaningful Logical Partition (LPAR) names to the configuration without a Power-On Reset is being introduced. Prior to this support, extra LPARs were defined by adding reserved names in the Input/Output Configuration Data Set (IOCDS), but one may not have been able to predict what might be meaningful names in advance.

Dynamic add/delete of an LPAR name allows reserved LPAR 'slots' to be created in an IOCDS in the form of extra Logical Channel Subsystem, Multiple Image Facility (MIF) image ID pairs. These extra Logical Channel Subsystem MIF image ID pairs (CSSID/MIFID) can be later assigned an LPAR name for use (or later removed) via dynamic I/O commands using the Hardware Configuration Definition (HCD). The IOCDS still must have the extra I/O slots defined in advance since many structures are built based upon these major I/O control blocks in the Hardware System Area (HSA). This support on zSeries is exclusive to the z890 and z990 and z/OS and z/OS.e V1.6.

Customer Initiated Upgrade Capacity -- Technology on demand

Customer Initiated Upgrade enhancement

When your business needs additional capacity quickly, Customer Initiated Upgrade (CIU) with the Express option is here to deliver it.

Customer Initiated Upgrade (CIU) is designed to allow you to respond to sudden increased capacity requirements by downloading and applying an IBM eServer zSeries Processor Unit (PU) and/or memory upgrade via the Web, using IBM Resource Link and the Remote Support Facility. IBM now has a faster process for upgrading your server. With the Express option on CIU, an upgrade may be installed as fast as within a few hours after order submission.

Permanent upgrades

Orders (MESs) of Processor Units (PUs) and memory for IBM eServer zSeries servers that can be delivered by Licensed Internal Code, Control Code (LIC CC) are eligible for CIU delivery. This includes the upgrade of PUs for z800, z900, z890, and z990 as well as memory for z900 and z990, and limited memory upgrades for z890 (24 GB to 32 GB) and z990 servers up to the maximum available on the installed server.

While capacity upgrades to the processor itself are concurrent, your software may not be able to take advantage of the increased capacity without performing an Initial Programming Load (IPL).

Temporary capacity

IBM eServer(TM) On/Off Capacity on Demand: When your business needs short-term additional capacity, On/Off Capacity on Demand (On/Off CoD) is designed to deliver it. On/Off Capacity on Demand is designed to temporarily turn on uncharacterized Processor Units (PUs) available within the current machine as CPs, Internal Coupling Facilities (ICFs), IFLs, and zSeries Application Assist Processors (zAAPs).

Activation of this capability is mutually exclusive with CBU activation. Both On/Off CoD and CBU can reside on the server, but only one can be activated at a time. On/Off CoD is delivered through the function of Customer Initiated Upgrade (CIU). To participate in this offering, you must have installed CIU Enablement (#9898) and On/Off CoD Enablement (#9896). Subsequently, you may concurrently install temporary capacity by ordering On/Off CoD Use Days (one of #6121 through #6471), On/Off CoD Active IFLs (#9888), On/Off Active ICFs (#9889), or On/Off CoD Active zAAP (#9893) up to the current capacity setting or the number of IFLs, ICFs, and zAAPs, respectively, and use the additional capacity for an indeterminate time. You will be billed for each On/Off CoD Active engine turned on in any given 24-hour period continuing until such On/Off CoD Active engine is turned off. Each month your bill will be calculated for the sum of all orders installed within the prior month. Monitoring will occur through the server call home facility and a bill will be generated if the capacity has been enabled for any portion of a calendar month. You will continue to be billed for use of temporary capacity until you return the server to the original state. After concurrently returning to the original state, you may choose to activate an On/Off CoD upgrade which can be different from the previous upgrade. When you dispose of the server, or decide that you want to disable future temporary upgrades, you are required to remove the enablement feature, On/Off CoD Enablement (#9896).

Connectivity Abounds

What's new with HiperSockets?

HiperSockets, first introduced in October, 2001, employs the Queued Direct Input/Output (QDIO) architecture for very high speed internal TCP/IP communication (network within the box - an independent internal LAN) between programs running on z/OS, z/OS.e, z/VM, or Linux on zSeries, or as guests under z/VM, whether in the same or in different LPARs on the same server. A synchronous data mover function transfers data at memory access speed with very low latency.

HiperSockets now supported by VSE/ESA: In VSE/ESA V2.7, IBM extended the support for HiperSockets to include the VSE/ESA environment. TCP/IP for VSE/ESA V1.5 (a new release) provides support for HiperSockets. Refer to Software Announcement 203-043, dated February 18, 2003.

HiperSockets VLAN support in a Linux environment: Virtual Local Area Networks (VLANs), IEEE standard 802.1q, are now being offered for HiperSockets in a Linux on zSeries environment. VLANs can reduce overhead by allowing networks to be organized for more optimal traffic flow; the network is organized by traffic patterns rather than physical location. This enhancement permits traffic to flow on a VLAN connection both over HiperSockets and between HiperSockets and an OSA-Express GbE, 1000BASE-T Ethernet, or Fast Ethernet feature.

HiperSockets - Up to 16 internal LANs: When HiperSockets was introduced, up to four internal Local Area Networks (LANs) could be configured. That number is now being increased to up to 16 internal LANs. A HiperSockets channel must be spanned in order to communicate between LPARs in different LCSSs.

This support is exclusive on zSeries on z890 and z990. There are no prerequisite software requirements.

HiperSockets broadcast support for IPv4 packets - Linux, z/OS, z/VM: Internet Protocol Version 4 (IPv4) broadcast packets are now supported over HiperSockets internal LANs. TCP/IP applications that support IPv4 broadcast, such as OMPROUTE when running Routing Information Protocol Version 1 (RIPv1), can send and receive broadcast packets over HiperSockets interfaces.

This support is exclusive on zSeries on z890 and z990. Broadcast for IPv4 packets is supported by z/OS V1.5 and later, z/VM V4.4 and later, as well as Linux on zSeries.

HiperSockets spanned channels: As previously mentioned, HiperSockets (CHPID type IQD) can be configured to multiple Channel SubSystems and transparently shared by any or all configured LPARs without regard to the LCSS to which the LPAR is configured. Refer to the Software Requirements section.

HiperSockets Network Concentrator simplifying network addressing: HiperSockets Network Concentrator simplifies network addressing between HiperSockets and OSA-Express, allowing seamless integration of HiperSockets-connected operating systems into external networks, without requiring intervening network routing overhead, thus helping to increase performance and simplify configuration.

HiperSockets Network Concentrator is implemented between HiperSockets, OSA-Express, and Linux on zSeries. HiperSockets Network Concentrator provides support for unicast, broadcast, and multicast. There is no z/VM guest LAN support planned for HiperSockets Network Concentrator.

HiperSockets Network Concentrator was previously referred to as HiperSockets Linux Layer 2 Switch support when it was announced on z990. HiperSockets Network Concentrator is exclusive on zSeries on z890 and z990.

A 75% increase in ESCON connectivity

With the introduction of two Logical Channel SubSystems (LCSSs), it is now possible to define up to a maximum of 420 ESCON channels on your z890 (240 on the smallest sub-uniprocessor equipped capacity setting), up to a maximum of 28 features. This can facilitate server consolidation. The maximum number of configurable CHPIDs is 256 per LCSS and per operating system image.

The high-density, 16-port Enterprise Systems CONnection (ESCON) feature can have 15 active channels. One is always reserved as a spare in the event of a failure of one of the other channels. When four channels are ordered, two 16-port ESCON features are installed and two channels are activated on each feature. After the first pair, ESCON features are installed in increments of one. ESCON channels continue to be ordered in increments of four.

ESCON supports five operating system environments: Enterprise Systems Connection (ESCON) is supported by OS/390, z/OS, and z/OS.e as well as z/VM, VSE/ESA, TPF, and Linux on zSeries. Refer to the

Fiber Quick Connect, an integrated "quick" connect for ESCON channels

Fiber Quick Connect (FQC), coupled with the IBM Fiber Transport System (FTS) from IBM Network Integration and Deployment Services for enterprise fiber cabling, delivers a solution designed to help reduce the amount of time required for on-site installation and setup of cabling, to help minimize disruptions, and to isolate the activity away from the active server as much as possible. FQC facilitates adds, moves, and changes of ESCON multimode fiber optic cables in the data center.

The Fiber Quick Connect feature, for factory installation of IBM Fiber Transport System (FTS) direct-attach fiber harnesses, may be the right answer for your installation, to help minimize the number of jumper cables exiting the server and residing under the floor. FQC supports all installed ESCON features in all installed I/O cages.

Cabling is a customer responsibility. Refer to the IBM Networking Services section for information on fiber optic cabling available from IBM Global Services.

Parallel channels no longer supported

Parallel channels features are not supported on z890, just as they are not supported on z800 or z990.

Customers who are still using parallel-attached devices can obtain a parallel channel converter product:

  • The IBM ESCON Converter Model 1, 9034-001, which may be available through IBM Global Financing (IGF).

  • A third-party parallel channel converter product such as the Optica 34600 FXBT.

FICON Express(TM) update

A 25% increase in the number of FICON Express channels: z890 supports up to a maximum of 20 FICON Express features, a total of 40 FICON channels (32 on the smallest sub-uniprocesor equipped capacity setting). This is a 25% growth over what was available on z800. Fibre Connection (FICON) Express continues to be a high-performance I/O channel optimized for efficient, high-speed communication. The FICON Express SX and LX features are capable of supporting an average of 3600 start I/Os per second on a channel that is 50% utilized. The FICON Express features (CHPID types FC and FCP) can be defined as a spanned channel and can be shared among LPARs within and across LCSSs.

The FICON Express features offer multiple I/O connectivity options:

      Function          CHPID Type             Connectivity
----------------------  ----------   --------------------------------
FICON Bridge              FCV        ESCON devices
FICON Native              FC         FICON devices
FICON CTC                 FC         Server-to-Server or LPAR-to-LPAR
Fibre Channel Protocol    FCP        SCSI disks / Linux
 

The FICON Express features support a 1 Gigabit per second (Gbps) or 2 Gbps link data rate, auto-negotiating the speed, point-to-point, without application or end-user intervention. Two features continue to be available -- FICON Express LX (long wavelength) for use with 9 micron single mode fiber optic cabling, and FICON Express SX (short wavelength) for use with 50 or 62.5 micron multimode fiber optic cabling.

The most common use of these features continues to be FICON Native with large infrastructures often feeding terabytes of storage.

FICON natively supports five operating system environments: FICON (CHPID type FC) is supported natively by OS/390, z/OS, z/OS.e as well as z/VM, VSE/ESA, TPF, and Linux on zSeries.

Fiber optic cabling is a customer responsibility.

Cascaded Director support: FICON Cascading enables two FICON Directors to be interconnected, or cascaded. FICON Cascading, used for cross-site connectivity, can help minimize the number of channels and cross-site connections helping to reduce implementation costs for disaster recovery applications such as Geographically Dispersed Parallel Sysplex(TM) (GDPS)(R) and Remote Copy. This support is applicable to z800, z900, z890, and z990. Support is offered in z/OS V1.3 with PTFs or later releases. Support is also available with z/VM V4.4, and later.

For more information on Cascaded Directors, consult the I/O Connectivity Web site at:

http://www.ibm.com/servers/eserver/zseries/ connectivity/ficoncascaded.html

Maximum unrepeated distance between cascaded directors: For information regarding the maximum unrepeated distance supported between cascaded directors, refer to the following Web site and select the specific director product of interest:

FCP for attachment to SCSI disks in Linux environments: The Fibre Channel Protocol (FCP) capability, supporting attachment to Small Computer Systems Interface (SCSI) disks in Linux on zSeries environments, was made available on z800 and z900 February 20, 2003. This support is also available on the z890. This support is applicable to all of the FICON Express features supported on z890 when configured as CHPID type FCP.

Refer to the connectivity Web site listed at the end of this section for updated information on supported devices.

For Linux on zSeries using FCP-attached SCSI disks and operating as a guest under z/VM, z/VM V4.3, and later, is required.

z/VM V5.1 supports SCSI-attached disks to be used for installation, IPL, and operation such as storing guest dumps, and other functions, while continuing to provide support for ESCON-or FICON-attached disk or tape.

z/VM SCSI support can allow a Linux server farm to be deployed on z/VM in a configuration that includes only SCSI disks.

FICON/FCP intermix: FICON/FCP intermix is supported on the McDATA Intrepid 6000 Series Directors and CNT FC/9000 Directors. Now a single director may be shared, on a port-by-port basis, between FICON-capable servers/devices and FCP-capable servers/devices.

FICON/FCP Intermix facilitates asset utilization. If you have chosen to implement small director footprints which can scale up over time, this may be of assistance as you pursue that strategy.

The Control Unit Port (CUP) continues to be used to communicate with operating systems, including Linux.

For additional details, refer to FICON/FCP White Papers which are available at the following Web sites.

FCP SAN management support: The zSeries 890 FICON Express features, when configured as FCP CHPID type, support the industry-standard interface for Storage Area Network (SAN) management tools. The FICON Express features may be used with industry-standard SAN management tools which leverage the Common Host Bus Adapter (HBA) Applications Programming Interface (API). The HBA API is used by management application programs to request SAN management services, enabling the management of Fibre Channel Host Bus Adapters (FC HBAs) and the discovery of SAN resources.

SAN management software tool support for exploiting the z890 function of FCP SAN Management is to be delivered by software vendors. Software vendors are now welcome to include the Linux on zSeries FICON Express features as an additional platform for SAN management tool development and exploitation.

Fibre Channel Protocol SCSI Initial Program Load: Small Computer System Interface (SCSI) Initial Program Load (IPL) allows the IPL of an operating system from a SCSI-type device attached via the zSeries FICON Express features when configured as a Fibre Channel Protocol channel (CHPID type FCP).

You may also IPL a standalone-dump program from a SCSI-type device attached via the zSeries FCP channel. The standalone dump program may also store the generated dump data on such a disk. Thus, the Linux-based LPARs may be started and operated completely from their FCP-attached disks in your hardware configuration. To use this function, a no-charge orderable platform feature (#9904) is required.

z/VM V4.4, and later, support of SCSI IPL allows Linux and other guest operating systems that support SCSI IPL to be IPLed from FCP-attached SCSI disks when z/VM is running on a z800, z900, z890, z990, or equivalent server equipped with the SCSI IPL function. Thus, Linux guests may be started and run completely from FCP disks on your hardware configuration. z/VM V5.1 plans to provide support that can allow z/VM to be IPLed from SCSI-attached FCP disks. Refer to the z/VM subset of the 2086DEVICE Preventive Service Planning (PSP) bucket for any service required for z/VM support for SCSI IPL.

FICON Express performance improvement: Relative to the FICON Express performance documented in the White Paper FICON and FICON Express Channel Performance Version 2.0, a customer may see an increase of up to 15% in the maximum of 4K I/O operations per second. This improvement is based on laboratory measurements. The actual I/O rate a customer may see will vary with factors such as the I/O configuration used and the level of the channel LIC installed. This performance improvement was achieved with the FICON Express LX feature (#2319) and the FICON Express SX feature (#2320) on z890 using the May 2004 level of LIC with measurements averaged over four channels.

FCP availability enhancement - FCP concurrent patch: FICON, when configured as CHPID type FCP, supports concurrent patch allowing application of Licensed Internal Code without requiring a configuration on / off. This is an exclusive FCP availability feature on zSeries offered on the z890 and z990 FICON Express features (#2319, 2320) when configured as CHPID type FCP. This concurrent patch capability requires the zSeries 890 May 2004, level of Licensed Internal Code.

Adding to the family of Directors supported by FICON: The FICON Express features now support attachment to the IBM M12 Director (2109-M12). A no-charge upgrade, Enterprise Operating System 4.1.2, is required for the IBM M12 Director.

The IBM M12 Director supports attachment of FICON Express channels on z890 via native FICON (CHPID type FC) and Fibre Channel Protocol (CHPID type FCP) supporting attachment to SCSI disks in Linux environments.

The FICON Express channels on the z890 continue to support attachment to McDATA Intrepid 6000 Series Directors and the CNT FC/9000 Directors.

The OSA-Express family of LAN adapters

Now 40 connections to your network - a 67% increase over z800 With the introduction of z890, its increased processing capacity, and the availability of two Logical Channel Subsystems, the Open Systems Adapter family of Local Area Network (LAN) adapters is also expanding by offering up to a maximum of 40 ports of LAN connectivity per z890 (24 ports on the smallest sub-uniprocessor equipped capacity setting). You can choose any combination of OSA-Express features: the OSA-Express Gigabit Ethernet LX (#1364), the OSA-Express Gigabit Ethernet SX (#1365), the OSA-Express 1000BASE-T Ethernet (#1366), and the current OSA-Express Token Ring (#2367). You can also carry forward on an upgrade from z800, OSA-Express Gigabit Ethernet LX (#2364), OSA-Express Gigabit Ethernet SX (#2365), OSA-Express Fast Ethernet (#2366), and OSA-Express Token Ring (#2367). There are no unique software requirements to support 40 connections.

OSA-Express Gigabit Ethernet features on z890: A new generation of Open Systems Adapter-Express (OSA-Express) Gigabit Ethernet (GbE) features first offered on zSeries with z990 is now also available on z890. New feature codes have also been introduced. These features are offered on new builds and replace the current OSA-Express GbE features (#2364, 2365) which can also be brought forward to z890 on an upgrade from z800. OSA-Express Gigabit Ethernet (CHPID type OSD) can be defined as a spanned channel and can be shared among LPARs within and across LCSSs.

The new OSA-Express Gigabit Ethernet SX (short wavelength) and OSA-Express Gigabit Ethernet LX (long wavelength) features support Checksum Offload, and have a new connector type, LC Duplex, replacing the current SC Duplex connector. This conforms to the fiber optic connectors currently in use for ISC-3 and the FICON Express features which began shipping October 31, 2001.

The new OSA-Express GbE features continue to be dual-port features occupying a single I/O slot, and utilize one CHPID per port, two CHPIDs per feature. The OSA-Express GbE features continue to support Queued Direct Input/Output (QDIO) mode only, full-duplex operation, and jumbo frames.

The current OSA-Express GbE features are supported on z890 on an upgrade from z800, OSA-Express Gigabit Ethernet LX (#2364) and OSA-Express Gigabit Ethernet SX (#2365). The connector remains the same, SC Duplex.

These new features on zSeries are exclusive to z890 and z990. There are no unique software dependencies for the new OSA-Express Gigabit Ethernet features, with the exception of the Checksum Offload support.

1000BASE-T Ethernet - a copper Ethernet: A copper Ethernet feature is being introduced on z890. This feature is offered on new builds and replaces the current OSA-Express Fast Ethernet (#2366) which can also be brought forward to z890 on an upgrade from z800. OSA-Express 1000BASE-T Ethernet (CHPID types OSC, OSD, OSE) can be defined as a spanned channel and can be shared among LPARs within and across LCSSs.

This new feature, 1000BASE-T Ethernet, is capable of operating at 10, 100, or 1000 Mbps (1 Gbps) using the same Category 5 Unshielded Twisted Pair (UTP) cabling infrastructure that is utilized for Fast Ethernet. The new Gigabit over copper adapter allows a migration to gigabit speeds wherever there is a copper cabling infrastructure instead of a fiber optic cabling infrastructure.

The new 1000BASE-T Ethernet feature supports:

  • Auto-negotiation (the target device must also be set to auto-negotiate)

  • A QDIO and a non-QDIO environment allowing you to make the most of your TCP/IP and SNA/APPN/HPR environments at up to gigabit speeds

  • Checksum Offload when in QDIO mode

When configured at 1 Gbps (1000 Mbps), the 1000BASE-T Ethernet feature has the following attributes:

  • Operates in QDIO mode or non-QDIO mode
  • Carries SNA (non-QDIO mode) and TCP/IP packets (QDIO or non-QDIO mode)
  • Operates in full-duplex mode only
  • Supports jumbo frames in QDIO mode

There are no unique software dependencies for the 1000BASE-T Ethernet feature, with the exception of the Checksum Offload support.

OSA-Express Integrated Console Controller: IBM is introducing a new function for the Open Systems Adapter-Express 1000BASE-T Ethernet feature and a new Channel Path Identifier (CHPID) type, OSC. The Open Systems Adapter-Express Integrated Console Controller (OSA-ICC) function supports TN3270E (RFC 2355) and non-SNA DFT 3270 emulation. Now, 3270 emulation for console session connections is integrated in the zSeries 890 via a port on the OSA-Express 1000BASE-T Ethernet feature. This can eliminate the requirement for external console controllers (2074, 3174), helping to reduce cost and complexity. Each port can support up to 120 console session connections.

OSA-ICC support on zSeries is exclusive to z890 and z990 and is available via the OSA-Express 1000BASE-T Ethernet feature, only. OSA-ICC can be configured on a port-by-port basis; a port on the 1000BASE-T Ethernet feature can be configured as CHPID type OSC, OSD, or OSE.

Refer to "IBM eServer zSeries 990 and 890 Open Systems Adapter-Express Integrated Console Controller User's Guide" (SA22-7990) for installation and setup assistance.

Checksum Offload for IPv4 packets when in QDIO mode - z/OS and Linux: A new function, Checksum Offload, offered for the new OSA-Express GbE and 1000BASE-T Ethernet features, is being introduced for the Linux on zSeries and z/OS environments. Checksum Offload provides the capability of calculating the Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Protocol (IP) header checksums. Checksum verifies the correctness of files. Because the checksum calculations are moved to a Gigabit or 1000BASE-T Ethernet feature, host CPU cycles are reduced and performance is improved.

When checksum is offloaded, the OSA-Express feature performs the checksum calculations for Internet Protocol Version 4 (IPv4) packets. This function applies to packets which actually go onto the Local Area Network (LAN) or come in from the LAN. When multiple IP stacks share an OSA-Express, and an IP stack sends a packet to a next hop address owned by another IP stack sharing the OSA-Express, OSA-Express sends the IP packet directly to the other IP stack without placing it out on the LAN. Checksum Offload does not apply to such IP packets. This function does not apply to IPv6 packets. TCP/IP will continue to perform all checksum processing for IPv6 packets. This function also does not apply to ICMP checksum processing. TCP/IP will continue to perform processing for ICMP checksum.

Checksum Offload is supported by the OSA-Express GbE features (#1364, 1365) and the 1000BASE-T Ethernet feature (#1366) when operating at 1000 Mbps (1 Gbps). This is applicable to the QDIO mode only.

Checksum offload support is available with z/OS V1.5. Refer to Software Announcement 203-131, dated May 13, 2003.

Full VLAN support for z/OS to increase traffic flow when in QDIO mode: z/OS Communications Server (CS) now supports Virtual Local Area Network Identifications (VLAN IDs). Support is offered for one global VLAN (ID) per Internet Protocol (IP) version per TCP/IP stack:

  • One global VLAN (ID) for IPv4 and
  • One global VLAN (ID) for IPv6

Previously CS supported VLAN priority tagging. CS will support both priority tagging and VLAN IDs.

VLAN support conforms to the IEEE 802.1q standard which defines a VLAN as a subset of the active topology of the LAN. VLANs ease the administration of logical groups of users so that they can communicate as if they were on the same LAN. VLANs can increase traffic flow and reduce overhead by allowing the organization of networks by traffic patterns rather than by physical location.

Full VLAN support is offered in z/OS V1.5 Communications Server. Full VLAN support is available on the following OSA-Express features: 1000BASE-T Ethernet (#1366), Fast Ethernet (#2366), and Gigabit Ethernet (#2364, 2365, 1364, 1365) when in QDIO mode. This support is applicable to z800, z900, z890, and z990. Refer to Software Announcement 203-131, dated May 13, 2003.

Virtual Local Area Network (VLAN) support for z/VM: z/VM V4.4, and later, exploits the VLAN technology and implements the IEEE 802.1q standard. TCP/IP for z/VM supports Virtual Local Area Network Identifications (VLAN IDs). In z/VM V4.4, support is offered for one global VLAN ID for IPv4. In z/VM V5.1, support is offered for one global VLAN ID for IPv6. The z/VM TCP/IP stack supports one VLAN ID per OSA-Express port. Each port can be configured with a different VLAN ID.

Support is offered for the following OSA-Express features: 1000BASE-T Ethernet (#1366), Fast Ethernet (#2366), and Gigabit Ethernet (#2364, 2365, 1364, 1365) when in QDIO mode. This support is applicable to z800, z900, z890, and z990.

Virtual Local Area Network (VLAN) support for Linux on zSeries: VLAN (IEEE 802.1q) support in a Linux on zSeries environment is supported for the OSA-Express Gigabit Ethernet, 1000BASE-T Ethernet, and Fast Ethernet features when in QDIO mode.

Intrusion Detection Services (IDS) enhancements: In z/OS V1.5 Communications Server, interface flood detection (Denial of Service - DoS) was added to the current IDS support. In the case where the interface flood is occurring on an OSA-Express QDIO interface, the source MAC address of packets can be identified. Intrusion Detection Services can help detect attacks on the TCP/IP stack that would potentially harm its ability to function normally and cause a misuse of server resources.

The source MAC identification feature on zSeries is exclusive to z890 and z990 and supported by all of the OSA-Express features on z890 when in QDIO mode (CHPID type OSD). Refer to Software Announcement 203-131, dated May 13, 2003.

Now 160 TCP/IP stacks per OSA-Express port when in QDIO mode: TCP/IP connectivity is now increased with the capability to allow up to a maximum of 160 IP stacks per OSA-Express port and 480 devices. There is up to a maximum of 84 IP stacks and 254 devices per LPAR. There continue to be four QDIO priorities. Previously, the OSA-Express features, when configured for QDIO, had been capable of supporting up to 80 IP stacks and 240 devices.

This support is applicable to all of the OSA-Express features available on z890, either as a new build z890 or on an upgrade from z800 when using QDIO mode (CHPID type OSD). This support is offered in the z890 Licensed Internal Code (LIC). There are no prerequisite software requirements.

OSA/SF Java GUI for client operating system independence: A new version of the Open Systems Adapter/Support Facility (OSA/SF) is available and includes a Java language-based Graphical User Interface (GUI) in support of the client application. The Java GUI is independent of any operating system/server (transparent to operating system), and is expected to operate wherever the Java 1.4 runtimes are available. Interoperability testing has been performed for Windows 2000, Windows XP, and Linux on zSeries. In the past, workstation support was downloaded to a client supporting Windows NT, Windows 95, or OS/2. Use of the GUI is optional; a REXX command interface is also included with OSA/SF. OSA/SF is not required to set up the OSA-Express features in QDIO mode (CHPID type OSD).

OSA/SF has been, and continues to be, integrated in z/OS (R), z/OS.e, OS/390(R), z/VM(TM), and VSE/ESA(TM) and runs as a host application. For OSA/SF, Java GUI communication is supported via TCP/IP only. In the past, communication was supported via EHLLAPI (3270), APPC, and TCP/IP.

This integrated version of OSA/SF is a complete replacement for the currently integrated versions in z/OS, z/OS.e, OS/390, and VSE/ESA. This version of OSA/SF is not being offered as a separately orderable program product.

The Open Systems Adapter/Support Facility (OSA/SF) is used primarily to:

  • Manage all OSA ports
  • Configure all OSA non-QDIO ports
  • Configure ATM LANE ports on G3 - G6 Servers, z800, and z900
  • Configure local MAC

This deliverable is a complete replacement for OSA/SF V2.1 (5655-B57). A separately orderable program product is no longer available. This integrated version is applicable to all in service releases of z/OS, z/OS.e, OS/390, z/VM, and VSE/ESA.

In the z/OS and z/OS.e environments, delivery will be via the z/OS V1.4 z990 Exploitation Support feature and the z/OS.e V1.4 z990 Coexistence Update feature and z990 Compatibility for Selected Releases Web deliverable (for releases OS/390 V2.10, z/OS V1.2, z/OS V1.3, and z/OS.e V1.3).

This version of OSA/SF is integrated in z/VM V4.4, and later, and replaces OSA/SF V2.1. In currently supported versions/releases of z/VM and VSE/ESA, the new version will be delivered as a PTF and will overlay OSA/SF V2.1.

This support is applicable to all OSA-Express and OSA-2 features on all supported servers.

Note: The OSA-2 features are not available on z890 nor z990.

OSA-Express SNMP update

The Simple Network Management Protocol (SNMP) allows network managers to monitor network devices and their functions, and identify problems in a TCP/IP environment. A separate standard, Management Information Base (MIB), defines the set of variables that SNMP servers maintain. The OSA-Express features support SNMP.

The OSA-Express Direct SNMP subagent and the OSA-Express Direct SNMP subagent MIB were first introduced for the QDIO mode only (CHPID type OSD). Prior to the introduction of the OSA-Express Direct SNMP subagent, OSA-Express management data was only available with the z/OS Communications Server TCP/IP subagent which required the Open Systems Adapter/Support Facility (OSA/SF) to obtain the data.

With the release of the OSA-Express Direct SNMP subagent, OSA/SF was no longer required to manage SNMP data for the OSA-Express features when configured in QDIO mode. With the introduction of Direct SNMP subagent support for LCS (see below), Direct SNMP subagent supported has been expanded to include TCP/IP when configuring a LAN Channel Station (LCS) connection when in non-QDIO mode (CHPID type OSE).

Traps and Set now supported: Enhanced support for the OSA-Express Direct SNMP subagent to include Traps and Set, is available, in addition to the previously released Get and GetNext support. Support for Traps and Set helps network managers to seamlessly integrate the zSeries OSA-Express features with the overall SNMP management strategy.

Trap support allows the SNMP manager to asynchronously receive an alert when one or more conditions are met, thus enabling a central source access to all information relating to the network connections. Direct SNMP users may configure the manager to send a Trap notification when the status of an OSA-Express port has changed.

Set support allows an SNMP manager to change a value identified by an Object Identifier (OID) in the OSA-Express Management Information Base (MIB). The initial object made settable in this implementation is the ability to set Traps on/off. Setting Traps "off" can be helpful if excessive Traps are being reported at the SNMP console.

Trap and Set support applies to all of the OSA-Express features supported on z890 and z990 when configured in QDIO mode (CHPID type OSD).

OSA-Express Direct SNMP subagent support for LCS: Expanded support for Direct Simple Network Management Protocol (SNMP) to now include TCP/IP when configuring a LAN Channel Station (LCS) connection is available. This applies to the non-QDIO mode (CHPID type OSE) when carrying TCP/IP traffic.

This support applies to all of the OSA-Express features supported on z890, and z990 and at availability will be exclusive in z/OS to z/OS V1.6. Direct SNMP for LCS when configured in non-QDIO mode supports the same SNMP requests and alerts offered in QDIO mode - Get, GetNext, Trap, Set.

In the past, Direct SNMP subagent support was exclusive to the QDIO mode (CHPID type OSD).

Performance data reflecting OSA-Express utilization: Usability enhancement via the Direct SNMP subagent to return performance data, in individual objects, for each image reflecting OSA-Express utilization without the need to "decode" a larger object that previously contained all of the information. The information returned includes the percentage of time the microprocessor was utilized to transfer data, as well as the number of inbound and outbound packets.

This support applies to all of the OSA-Express features supported on z800, z900, z890 and z990 when configured in QDIO mode (CHPID type OSD).

Summarizing the OSA-Express Direct SNMP subagent support offered via the OSA-Express features that is available via zSeries 890 Licensed Internal Code (LIC):

  • Get and GetNext requests

    • Applies to all of the OSA-Express features supported on z800, z900, z890, and z990 when configured in QDIO mode (CHPID type OSD).

  • dot3StatsTable applies to the SNMP EtherLike Management Information Base (MIB) module in RFC 2665 which provides statistics for Ethernet interfaces. These statistics can assist in the analysis of network traffic congestion.

    • Applies to all of the Ethernet features supported on z800, z900, z890, and z990 when configured in QDIO mode (CHPID type OSD).

    • Applies to all of the OSA-Express features supported on z800, z900, z890, and z990 when configured in QDIO mode (CHPID type OSD).

  • Traps and Set

    • Applies to all of the OSA-Express features supported on z890 and z990 when configured in QDIO mode (CHPID type OSD).

    • Applies to all of the OSA-Express features supported on z890 and z990 when configured in non-QDIO mode (CHPID type OSE) supporting TCP/IP applications only and the same SNMP requests and alerts offered in QDIO mode - Get, GetNext, Trap, Set.

    • Applies in z/OS exclusively to the z/OS V1.6 environment.

For more information on SNMP support as well as the applicable features and modes of operation, refer to the "Open Systems Adapter-Express Customer's Guide and Reference" (SA22-7935).

The zSeries 890 May 2004, Licensed Internal Code includes support for the following:

  • Get and GetNext
  • dot3StatsTable
  • New Gigabit Ethernet features
  • New 1000BASE-T Ethernet feature
  • Logical Channel SubSystems (LCSSs)
  • Updated performance table with more detailed information
  • Traps and Set
  • Direct SNMP for LCS when configured in non-QDIO mode

Note: Direct SNMP for LCS when configured in non-QDIO mode is planned to be available in the z/OS V1.6 timeframe.

The OSA-Express Direct SNMP subagent MIB information can be found on Resource Link.

If you subscribe to the document, OSA-Express Direct SNMP subagent MIB module, you will receive e-mail notification of document changes.

OSA-Express usability enhancement - Port name relief: When configuring an OSA-Express feature in QDIO mode (CHPID type OSD), specification of a PORTNAME is no longer required as part of the operating system configuration and can be omitted if not needed by the operating system. For compatibility purposes, OSA-Express will now permit activation with or without a PORTNAME.

Prior to this change, operating system administrators that wished to share an OSA-Express were required to coordinate the configuration of the PORTNAME (configure matching names). If a mismatch occurred, activation would fail. To avoid the coordination effort when multiple operating systems share an OSA-Express, this usability enhancement has been introduced.

Operating Systems notes:

  1. z/OS

    z/OS Communications Server (z/OS CS) still requires the use of the OSA-Express PORTNAME. The PORTNAME must be the same among all z/OS systems (or any operating system that still uses PORTNAME) sharing the OSA-Express CHPID.

  2. z/VM

    In a z/VM environment when using a guest LAN with a simulated OSA-Express QDIO feature, the PORTNAME may now be omitted when configuring the device. For example, in z/VM TCPIP the PORTNAME is specified on the OSD DEVICE statement and now may be omitted. Linux on zSeries guests may now omit the PORTNAME in the add_parms command of the qeth interface parameters.

    For z/VM V4.3 co-requisites refer to the z/VM subset of the 2086DEVICE Preventive Service Planning (PSP) bucket. This function is integrated in z/VM V4.4.

  3. Linux on zSeries images may now omit the PORTNAME in the add_parms command of the qeth interface parameters.

This usability enhancement is supported on all of the OSA-Express features offered on z800, z900, z890, and z990. This support is applicable to all of the OSA-Express features in QDIO mode (CHPID type OSD).

Introducing new OSA-Express GbE features on z800: New OSA-Express Gigabit Ethernet (GbE) features are being introduced on z800, to replace the currently available OSA-Express GbE features. OSA-Express Gigabit Ethernet LX feature #1364 replaces #2364. OSA-Express Gigabit Ethernet SX featue #1365 replaces #2365. The functions of these OSA-Express Gigabit Ethernet features are equal to the functions currently available on z800. There are no changes. There are no unique software requirements.

These new GbE features have a new connector type, LC Duplex, replacing the current SC Duplex connector. This conforms to the fiber optic connectors currently in use for the ISC-3 and FICON Express features on z800.

When #1364 and 1365 are made available third quarter, 2004, #2364 and 2365 will no longer be orderable. There are no unique software dependencies for the OSA-Express Gigabit Ethernet features on z800.

OSA-Express Token Ring outlook:

The demand for Token Ring in mainframe environments continues to decline. IBM zSeries is seeing an increasing shortage of Token Ring components as suppliers discontinue the manufacture of Token Ring.

A migration from a Token Ring to an Ethernet environment should be a part of all long-term LAN planning.

OSA-Express ATM no longer supported:

The OSA-Express Asynchronous Transfer Mode (ATM) features are not supported on z890. ATM is not offered as a new build option on z890 and ATM is not offered on an upgrade from z800.

If ATM connectivity is still desired, a multiprotocol switch or router with the appropriate network interface (for example, 1000BASE-T Ethernet, Gigabit Ethernet) can be used to provide connectivity between the z890 and an ATM network.

Further integration of cryptographic support with z890

New cryptographic function on every Central Processor (CP): To achieve the required throughput and implement new functions while maintaining balanced usage of server resources, integrated hardware is key. zSeries introduces the Message Security Assist Architecture along with the CP Assist for Cryptographic Function (CPACF) delivering cryptographic support on every Central Processor (CP) -- data encryption and decryption with support of Data Encryption Standard (DES), Triple Data Encryption Standard (TDES), and Secure Hash Algorithm-1 (SHA-1). This offers balanced use of server resources and is designed to provide unprecedented scalability -- a z890 can have from one to four CPs, depending upon capacity setting, and data rates at up to 1.8X or more faster than the CMOS Cryptographic Coprocessor Facility (CCF). Since these cryptographic functions are implemented in each and every CP, the association of cryptographic functions to specific CPs, as was done with previous generations of zSeries, is eliminated.

The DES and TDES functions use clear key values. The SHA-1 function is shipped enabled. However, DES and TDES functions require enablement of the CPACF function (#3863) for export control.

For IBM and customer-written programs, the CPACF for DES, TDES, and SHA-1 functions can be invoked by five problem state instructions as defined by an extension to the zSeries architecture.

PCIXCC for more secure encrypted transactions with higher performance: The PCIX Cryptographic Coprocessor (PCIXCC) (#0868) is a replacement for the PCI Cryptographic Coprocessor (PCICC) (#0861) and the CMOS Cryptographic Coprocessor Facility that were offered on z800. All of the equivalent PCICC functions that are implemented are designed to offer higher performance. In addition, the functions on the CMOS Cryptographic Coprocessor Facility used by known applications have also been implemented in the PCIXCC feature. All LPARs in all LCSSs have access to the PCIXCC, up to 16 LPARs per feature. While a PCIXCC feature occupies an I/O slot it does not use CHPIDs.

The PCIXCC feature supports:

  • Cryptographic functions
  • Use of encrypted key values
  • User-Defined Extensions

The CPACF feature (#3863) must be enabled to use the PCIXCC feature.

z/VM V5.1 provides dedicated-queue support for secure key and clear key cryptographic functions for z/OS guests and shared-queue and dedicated-queue support for clear key cryptographic functions for Linux guests, with up to 256 dedicated queues, using the PCIXCC feature.

Linux on zSeries support for the PCIXCC feature was delivered as an Open Source contribution via:

http://www10.software.ibm.com/developerworks/ opensource/linux390

PCIXCC User-Defined Extensions to support unique requirements: User-Defined Extensions to the Common Cryptographic Architecture (CCA) support program that executes within the PCIX Cryptographic Coprocessor are expected to be supported via an IBM Service Offering. For unique customer applications, the PCIX Cryptographic Coprocessor will support the loading of customized cryptographic functions on z890. Support is available via ICSF and the z990 and z890 Enhancements to Cryptographic Support Web deliverable.

Under a special contract with IBM, PCIX Cryptographic Coprocessor customers will gain the flexibility to define and load custom cryptographic functions themselves. This service offering can be requested via the IBM 'Cryptocards' Web site by selecting the 'Custom Programming' option.

The Web site will direct your request to an IBM Global Services (IGS) location appropriate for your geographic location. A special contract will be negotiated between you and IGS, covering development of the UDX by IGS per your specifications as well as an agreed-upon level of the UDX. The contract may also include e-mail, telephone, or on-site support if s negotiated (IGS may subcontract any piece of this work to a third-party vendor).

The CP Assist for Cryptographic function (#3863) is a prerequisite when ordering the PCICA and PCIXCC features and utilizing any of the functions/enhancements identified here.

PCIXCC support for double length DUKPT: Derived Unique Key Per Transaction (DUKPT) is a key management method that allows you to write applications that implement the DUKPT algorithm as defined by the ANSI X9.24 standard, providing added security for point of sale transactions. At introduction, IBM supported single length DUKPT on zSeries 990. Now, IBM is introducing support for double length DUKPT on the z890 and z990 for the PCIXCC feature. This support on OS/390 and z/OS is exclusive to the OS/390 V2.10, z/OS, and z/OS.e environments and is part of the ICSF Web deliverable z990 and z890 Enhancements to Cryptographic Support. Refer to the Software Requirements for further information.

PCIXCC support for EMV 2000 Standard: Europay Mastercard and Visa (EMV) support allows you to write applications that comply with the EMV 2000 standard, which is used for financial transactions among heterogeneous hardware and software. Support for the EMV 2000 standard applies only to the PCIXCC feature and to z890 and z990. This support on OS/390 and z/OS is exclusive to the OS/390 V2.10, z/OS, and z/OS.e environments and is part of the ICSF Web deliverable z990 and z890 Enhancements to Cryptographic Support.

PCICA and PCIXCC support for PKD service enhancement: The Public Key Decrypt (PKD) service has been upgraded to support a Zero-Pad option for clear RSA private keys. With this support, PKD can be used as an accelerator for raw RSA private operations, including the use of CRT format keys. This enhancement applies to z890 and z990, to the OS/390 V2.10, z/OS, and z/OS.e environments, and is part of the ICSF Web deliverable z990 and z890 Enhancements to Cryptographic Support.

PCICA and PCIXCC support for PKE service enhancement: The Public Key Encrypt (PKE) service has been enhanced to support the Mod_Raised_to Power (MRP) function. The MRP function can be used to offload the compute-intensive portion of the Diffie-Hellman protocol for both the PCICA and PCIXCC features for improved performance and more efficient use of CP resources. This enhancement on OS/390 and z/OS, applies to z890 and z990, and is exclusive to the OS/390 V2.10, z/OS, and z/OS.e environments, and is part of the ICSF Web deliverable z990 and z890 Enhancements to Cryptographic Support.

PCICA - Continued cryptographic support for e-business environments: The PCI Cryptographic Accelerator (PCICA) feature, supported on z800, is available on z890 and may be carried forward on upgrades from z800 to z890. This hardware-based cryptographic solution continues to address the Secure Sockets Layer (SSL) performance needs of on demand businesses. The SSL and Transport Layer Security (TLS) protocols are essential and widely used protocols to help support secure e-business applications. Compute-intensive public key cryptographic processes as used by SSL/TLS can be offloaded from the host to the PCICA feature to help reduce CP usage and to increase system throughput. All LPARs in all LCSSs have access to the PCICA, up to 30 LPARs per feature. While a PCICA feature occupies an I/O slot it does not use CHPIDs.

The z890 server is designed to provide increased secure Web transaction performance by supporting up to 2,900 SSL handshakes per second when running on a properly configured system. The SSL rate was achieved with a z890 with 4 processors and 4 PCICA cards (2 features), May 2004 licensed internal code, z/OS V1R5 with z890 support, ICSF FMID HCR 770A, and SSL R14 driver. These measurements are examples of the maximum transactions per second achieved in a lab environment with no other processing occurring and do not represent actual field measurements. Details are available upon request. To enable the use of the PCICA feature, the CPACF feature (#3863) must be installed.

Beginning with z/VM V4.2, z/VM support of PCICA provides clear key RSA support for a considerably large number of Linux guests enabling hardware Secure Sockets Layer (SSL) acceleration. z/VM V5.1 will provide dedicated-queue support for clear key cryptographic functions for z/OS guests and shared-queue support for clear key cryptographic functions for Linux guests.

With VSE/ESA V2.7 and IBM TCP/IP for VSE/ESA V1.5, support is offered for the PCICA feature.

Trusted Key Entry (TKE) 4.1 code level workstation: The TKE 4.1 code level workstation is an optionally priced feature that provides a basic key management system. The key management system allows an authorized person a method for key identification, exchange, separation, update, backup, and management. The TKE workstation is a tool for security administrators to use in setting up and establishing the security policy and placing it into production. The TKE feature is a combination of workstation hardware and software networked-connected to z890. The TKE workstation and 4.1 code level are designed to provide a security-rich, flexible method of providing master key entry (and now operational key entry), and to locally and remotely manage Cryptographic Coprocessor features.

TKE 4.1 code level for secure operational key entry: The Trusted Key Entry (TKE) 4.1 code now provides a security-rich local and remote method of providing operational key entry, along with the master key entry that was previously announced. This support applies to the Cryptographic Coprocessor features and is exclusive to z890 and z990.

Operational key entry via the TKE workstation satisfies the Statement of General Direction in Hardware Announcement 103-142, dated May 13, 2003. Customers with TKE 3.X installed workstations may carry them forward to control legacy systems only. An update from TKE 3.0 or TKE 3.1 code levels to TKE 4.1 code level is required to control the z890. To use the TKE function, the PCIX Cryptographic Coprocessor (PCIXCC) feature, the TKE 4.1 code level, and the CP Assist for Cryptographic Function (CPACF) must be installed.

z890 cryptographic migration: The IBM PCI Cryptographic Accelerator (#0862) is supported on z890, and can be carried forward on an upgrade from z800.

Fiber optic cabling services from IBM Networking Services

Fiber optic cabling complexity continues to be a reality of the Information Technology (IT) infrastructure as diverse protocols (ESCON, FICON, FCP, Gigabit Ethernet) and industry-standard small form factor (SFF) connectors continue to proliferate in the enterprise. If your enterprise has multiple generations of products, the problem can be exacerbated. Even more critical is the availability of skills and dedicated personnel tasked to support the short-term as well as the long-term requirements of the IT infrastructure in addition to supporting the open systems e-business environment.

To satisfy the cabling requirements of z800, z900, z890, and z990, IBM Networking Services has fiber optic cabling services. IBM Network Integration and Deployment Services for zSeries fiber cabling provides planning and installation services for individual fiber optic connections. IBM Network Integration and Deployment Services for enterprise fiber cabling provides planning for IBM Fiber Transport System trunking components and installation services for small, medium, and large enterprises.

IBM Networking Services is continually working to help ensure IBM has a comprehensive set of services geared for today and tomorrow. These services take into consideration the requirements for all of the protocols and media types supported on zSeries (for example, ESCON, FICON, Coupling Links, OSA), whether the focus is the data center, the Storage Area Network (SAN), the Local Area Network (LAN), or the end-to-end enterprise.

Fiber optic cabling services from IBM Networking Services makes the most of your cabling investments. IBM has the skills to facilitate the design and installation of your cabling with the consulting services so critical when the clock matters. Knowing that new installations, upgrades, and relocations require intelligent execution, IBM offers comprehensive solutions to help reduce the complexity and simplify the process. The zSeries fiber cabling services and enterprise fiber cabling services have been designed to solve the IT infrastructure dilemmas at the product level and the enterprise level.

These services can meet the needs of your server configurations be they small, medium, or large. IBM connectivity experts will help you select the option that is best suited to achieve your business goals, and to simplify the zSeries deployment with effective on-site fiber optic cable planning and installation support.

Fiber optic cables, cable planning, labeling, and installation are all customer responsibilities for new z890 installations and upgrades. Fiber optic conversion kits and Mode Conditioning Patch (MCP) cables are not orderable as features on z890. Installation Planning Representatives (IPRs) and System Service Representatives (SSRs) will not perform the fiber optic cabling tasks without a services contract.

Under the zSeries fiber cabling services umbrella there are three options to provide individual fiber optic cables (jumper cables, conversion kits, MCP cables) for connecting to z800, z900, z990, or z890.

  • Option 1 - Fiber optic jumper cabling package: IBM does the detailed planning. This option includes planning, new cables, installation, and documentation. An analysis of the zSeries channel configuration, I/O devices, and any existing fiber optic cabling is required to determine the appropriate fiber optic cables.

  • Option 2 - Fiber optic jumper cable migration and reuse for a zSeries upgrade. This option includes planning, reuse of existing cables, and documentation. IBM organizes the existing fiber optic cables based upon the new z890 connection details. Relabeling, rerouting, and reconnection to the appropriate z890 channels are performed. New cables are not offered as a part of this option.

  • Option 3 - Fiber optic jumper cables and installation. You tell us what you need. You do the detailed planning. The service includes cables, installation, and documentation. Planning and providing the list of required cables are customer responsibilities.

Options 1 and 2 can be combined within one statement of work to provide comprehensive upgrade coverage.

Under the enterprise fiber cabling services umbrella there are two options to provide fiber optic trunk cables (fiber optic trunk cables, fiber harnesses, panel-mount boxes) for connecting to the z800, z900, z890, and z990.

  • Option 1 - zSeries fiber optic trunk cabling package: IBM can reduce the cable clutter under the floor. An analysis of the zSeries (z800, z900, z890, and z990) channel configuration and any existing fiber optic cabling is performed to determine the required FTS fiber optic trunking commodities (trunk cables, harnesses, panel-mount boxes). This option includes zSeries planning, FTS fiber optic trunking commodities, installation, and documentation. This option does not include enterpise-level planning.

  • Option 2 - Enterprise fiber cabling services. IBM organizes the entire enterprise zSeries cabling. This option includes enterprise planning, new cables, fiber optic trunking commodities, installation, and documentation. This is the most comprehensive set of services of the two options.

A comprehensive evaluation of the enterprise helps to ensure your long-term planning goals can be achieved.

Enterprise fiber cabling services employ the use of a proven modular cabling system, the Fiber Transport System (FTS), which includes trunk cables, zone cabinets, and panels for your servers, directors, and storage devices.

FTS supports Fiber Quick Connect (FQC), a fiber harness integrated in the zSeries frame for "quick" connect, which is offered as a feature on zSeries for connection to ESCON channels.

Whether you choose a packaged service or a custom service, high-quality components are used to facilitate moves, adds, and changes in the enterprise to help prevent extending your maintenance "window."

Parallel Sysplex Marches On

Enhancing the scalability of Parallel Sysplex

Coupling Facility Control Code (CFCC) Level 13: A new CFCC level available for the z890, CFCC level 13 provides Parallel Sysplex availability and performance enhancements.

Coupling Facility Control Code (CFCC) enhanced patch apply: The CFCC patch apply process has been enhanced to eliminate the need for a power on reset (POR) of the z890 to apply a "disruptive" CFCC patch. This enhancement provides you the ability to:

  • Selectively apply the new patch to one of possibly several CFs running on a z890. For example, if you have a CF that supports a test Parallel Sysplex and a CF that supports a production Parallel Sysplex on the same z890, you now have the ability to apply a "disruptive" patch to only the test CF without affecting the production CF. After you have completed testing of the patch, it can be applied to the production CF as identified in the example.

  • Allows all other LPARs on the z990 where a "disruptive" CFCC patch will be applied to continue to run without being impacted by the application of the "disruptive" CFCC patch.

This enhancement does not change the characteristics of a "concurrent" CFCC patch, but does significantly enhance the availability characteristics of a "disruptive" CFCC patch by making it much less disruptive.

Previously, small enhancements or "fixes" to the CFCC were usually distributed as a "concurrent" patch that could be applied while the CF was running. Occasionally, a CFCC patch was "disruptive." When such a "disruptive" change needed to be applied to a CF, it required a POR of the server where the CF was running. This was especially disruptive for those enterprises that had chosen to use internal CFs, because a POR of the server affects the CF where the change was to be applied and all other LPARs running on the same server. Further, if an enterprise was using multiple internal CFs on the same server (to support both a test and production configurations, for example), there was no way to selectively apply the "disruptive" patch to just one of the CFs - once applied, all the CFs on the server had the change. Consequently, the application of the "disruptive" CFCC patch was very disruptive from an operations and availability perspective.

Additional CFCC Enhancements:

CFCC level 13 also provides changes that will affect different software environments that run within a Parallel Sysplex. For example, DB2 data sharing is expected to see a performance improvement, especially for cast-out processing against very large DB2 group buffer pool structures.

Enhancing the availability of Parallel Sysplex

z890 fully supports System-Managed CF Structure Duplexing. This is a set of architectural extensions to Parallel Sysplex in support of duplexing of Coupling Facility structures for high availability. All three structure types -- cache structures, list structures, and locking structures -- can be duplexed using this architecture.

The IBM technical paper, System Managed CF Structure Duplexing (GM13-0103) includes information about:

  • The cost/benefit trade-offs in duplexing
  • Determining which structures should be duplexed in a specific Parallel Sysplex

z890 Coupling Link options for Parallel Sysplex

ICs, ICBs, and ISC-3 on z890: Like its predecessor, z890 supports Internal Coupling Channels (ICs), Integrated Cluster Bus (ICB), and InterSystem Channel-3 (ISC-3) for passing information back and forth in a Parallel Sysplex environment. These technologies are all members of the family of Coupling connectivity options available on z890.

Internal Coupling Channels (ICs) are for internal communication between Coupling Facilities and to other CFs or to z/OS images on the same server. ICs (CHPID type ICP) can be defined as spanned channels and can be shared among LPARs within and across LCSSs.

Integrated Cluster Buses (ICBs) are used for server-to-server communication over short distances. The newest ICB member, ICB-4, supports a link data rate of 2 gigabytes per second (GBps), compared to ICB-3, which supports a link data rate of 1 GBps. ICBs carry traffic over 10 meter (33 feet) copper cables, of which 3 meters is reserved for intra-server connection. ICB-3s and ICB-4s (CHPID type CBP) can be defined as spanned channels and can be shared among LPARs within and across LCSSs. z890 supports ICB-3 and ICB-4. z890 does not support ICB-2.

InterSystem Channel-3s (ISC-3s) are used for server-to-server communication over long distances -- up to an unrepeated distance of 20 kilometers. ISC-3 supports a link data rate of 2 gigabits per second (Gbps) and carries traffic over 9 micron single mode fiber optic cabling. If the ISC-3 link is connected to another zSeries server and defined as a peer (CFP) mode channel, the link operates in peer mode, and the link is capable of 2 Gbps. The peer mode is used between zSeries servers only. If the link is connected to a coupling-capable server (G5/G6) which is not a zSeries and is defined as a sender/receiver (CHPID types CFS/CFR) channel, the link operates in compatibility mode, and the link is capable of 1 Gbps. The compatibility mode is used between a zSeries server and 9672 coupling-capable servers. ISC-3s (CHPID type CFS - Coupling Sender, compatibility mode, or CHPID type CFP - peer) can be defined as spanned channels and can be shared among LPARs within and across LCSSs.

Up to a 100% increase in ISC-3 physical connectivity vs z800: To continue to provide "horizontal" growth opportunities for Parallel Sysplex solutions, zSeries 890 is doubling the number of InterSystem Channel-3 (ISC-3) links, now supporting 48 ISC-3 link in peer mode -- 12 features (four links per feature) versus the 24 ISC-3 links in peer mode offered on z800.

The family of Coupling Link options available on z890 is as follows:

Link                                                            Maximum
Type              Name                  Communication Use        Links
-----     ------------------------     --------------------     -------
IC        Internal Coupling channel     Internal between         32
                                        CFs and z/OS LPARs
 
ICB-3     Integrated Cluster Bus-3      Server-to-server         16
                                        z890 to z800, z900
 
ICB-4     Integrated Cluster Bus-4      Server-to-Server          8
                                        z890 to z890, z990
 
ISC-3     InterSystem Channel-3         Server-to-server         48
 

  1. The maximum number of Coupling Links combined (ICs, ICB-3s, ICB-4s, and active ISC-3 links) cannot exceed 64 per server.

  2. A maximum of 48 ISC-3s can be defined in peer mode (operating at a link data rate of 2 Gbps) and a maximum of 32 ISC-3s can be defined in compatibility mode (operating at 1 Gbps, instead of 2 Gbps).

  3. An ISC-3 feature on a z890 can be connected to another zSeries server in peer mode (CHPID type CFP) operating at 2 Gbps or to a HiPerLink (ISC-2) on a G5/G6 in compatibility mode (CHPID type CFS/CFR - sender/receiver) operating at 1 Gbps.

Geographically Dispersed Parallel Sysplex (GDPS) enhancements Geographically Dispersed Parallel Sysplex(TM), (GDPS) (R), an industry-leading e-business continuity solution, is a multisite solution that is designed to provide the capability to manage the remote copy configuration and storage subsystems, automate Parallel Sysplex operational tasks, and perform failure recovery from a single point of control, thereby helping to improve application availability. GDPS supports both the synchronous Peer-to-Peer Remote Copy (PPRC), as well as the asynchronous Extended Remote Copy (XRC) forms of remote copy. Depending on the form of remote copy, the solution is referred to as GDPS/PPRC or GDPS/XRC.

GDPS/PPRC and GDPS/XRC have been enhanced to include new functions.

GDPS/PPRC HyperSwap(TM) function: The GDPS/PPRC HyperSwap function is designed to broaden the availability attributes of GDPS/PPRC by extending the Parallel Sysplex redundancy to disk subsystems.

The Planned HyperSwap function provides the ability to:

  • Transparently switch all primary PPRC disk subsystems with the secondary PPRC disk subsystems for a planned reconfiguration.

  • Perform disk configuration maintenance and planned site maintenance without requiring any applications to be quiesced.

The Unplanned HyperSwap function contains additional function to transparently switch to use secondary PPRC disk subsystems in the event of unplanned outages of the primary PPRC disk subsystems or a failure of the site containing the primary PPRC disk subsystems.

The Unplanned HyperSwap function allows:

  • Production systems to remain active during a disk subsystem failure. Disk subsystem failures will no longer constitute a single point of failure for an entire Parallel Sysplex.

  • Production servers to remain active during a failure of the site containing the primary PPRC disk subsystems if applications are cloned and exploiting data sharing across the two sites. Even though the workload in the second site will need to be restarted, an improvement in the Recovery Time Objective (RTO) can be accomplished.

GDPS/PPRC management for open systems Logical Unit Numbers (LUNs): GDPS/PPRC technology has been extended to manage a heterogeneous environment of z/OS and open systems data. If installations share their disk subsystems between the z/OS and open systems platforms, GDPS/PPRC, running in a z/OS system, can manage the PPRC status of devices that belong to the other platforms and are not even defined to the z/OS platform. GDPS/PPRC will also provide data consistency across both z/OS and open systems data.

GDPS supports PPRC over Fibre Channel links: IBM TotalStorage Enterprise Storage Server (ESS) supports PPRC over Fibre Channel for the ESS Model 800. Refer to Hardware Announcement 103-298, dated October 14, 2003.

This support is designed to provide improved throughput (compared to ESCON), and a reduction in cross-site connectivity (two PPRC Fibre Channel links per ESS are considered sufficient for most customer workloads).

One of the potential benefits of this support is the ability for customers to increase the distance between sites while maintaining acceptable performance. GDPS/PPRC support for PPRC over Fibre Channel became generally available February 2004.

GDPS supports FlashCopy (R) v2 elimination of the LSS constraint: IBM TotalStorage Enterprise Storage Server (ESS) supports of FlashCopy v2. Refer to Hardware Announcement 103-141, dated May 13, 2003. Prior, both source and target volumes had to reside on the same logical subsystem (LSS) within the disksubsystem. Since this constraint has been removed with FlashCopy v2, GDPS will now allow a FlashCopy from a source in one LSS to a target in a different LSS within the same disk subsystem. This new flexibility can help simplify administration and capacity planning for FlashCopy.

GDPS/PPRC and Cross-site Parallel Sysplex distance extended to 100 km: Via a Request for Price Quote (RPQ), the capability to configure GDPS/PPRC or a multi-site Parallel Sysplex up to a distance of 100 kilometers (62 miles) between two sites is available. This extended distance can potentially decrease the risk that the same disaster will affect both sites, thus permitting enterprises to recover production applications at another site.

Support has been extended up to a distance of 100 km from the current capability of 50 km (31 miles) for:

  • External Time Reference (ETR) links
      An ETR link on a zSeries or S/390 server provides attachment to the Sysplex Timer.

  • InterSystem Channel-3 (ISC-3) links operating in peer mode
      ISC-3 links, supported on all zSeries servers, connect z/OS and OS/390 systems to Coupling Facilities in a Parallel Sysplex environment.

The extended distance support for ETR and ISC-3 links is now consistent with other cross-site link technologies that currently support 100 km between two sites (such as FICON, Peer-to-Peer Remote Copy (PPRC), Peer-to-Peer Virtual Tape Server (PtP VTS)).

It should be noted that the maximum fiber optic cable distance between a pair of Sysplex Timers in an Expanded Availability configuration remains at 40 km (25 miles). Therefore, to achieve the extended distance of 100 km between sites, one of the options to be considered is locating one of the Sysplex Timers in an intermediary site that is less than 40 km from one of the two sites. Other potential options can be evaluated when the RPQ request is submitted to IBM for review.

Coordinated near continuous availability and disaster recovery for Linux guests:

GDPS plans to exploit the new z/VM HyperSwap function to provide a coordinated near continuous availability and disaster recovery solution for z/OS and Linux guests running under z/VM. z/VM 5.1 provides a new HyperSwap function, so that the virtual device associated with one real disk can be swapped transparently to another. HyperSwap can be used to switch to secondary disk storage subsystems mirrored by PPRC. This solution is especially valuable for customers who share data and storage subsystems between z/OS and Linux on zSeries - for example, a SAP application server running on Linux on zSeries and a SAP DB server running on z/OS. HyperSwap can also be helpful in data migration scenarios to allow applications to migrate to new disk volumes without requiring them to be quiesced.

GDPS/PPRC will provide the reconfiguration capabilities for the Linux on zSeries systems and data in the same manner it does for z/OS systems and data. To support planned and unplanned outages, GDPS provides the following recovery actions:

  • In place re-IPL of failing operating system images

  • Site takeover/failover of a complete production site

  • Coordinated planned and unplanned HyperSwap of disk subsystems, transparent to the operating system images and applications using the disks.

This innovative continuous availability and disaster recovery solution requires IBM Tivoli System Automation for Linux, and z/VM V5.1 in addition to the other GDPS/PPRC prerequisites.

Performance enhancements for GDPS/PPRC and GDPS/XRC configurations

Concurrent activation of Capacity Backup Upgrade (CBU) can now be performed in parallel across multiple servers, which results in an improved RTO. This improvement applies to both the GDPS/PPRC and GDPS/XRC configurations.

In a GDPS/XRC configuration, it is often necessary to have multiple System Data Movers (SDMs). The number of SDMs is based on many factors, such as the number of volumes being copied and the I/O rate. Functions are now capable of being executed in parallel across multiple SDMs, thus providing improved scalability for a coupled SDM configuration.

Analysis has shown that PPRC commands issued by GDPS will generate a large number of Write to Operator messages (WTOs) that may cause WTO buffer shortages and temporarily adversely impact system performance. The Message Flooding Automation function will substantially reduce the WTO message traffic and improve system performance by suppressing redundant WTOs.

These GDPS enhancements are applicable to z800, z900, z890, and z990.

SNA operations management

With the industry move to TCP/IP networks, Systems Network Architecture (SNA) Operations Management commands will no longer be supported on z890 servers. These commands were previously used by the System Automation for OS/390 product as well as NetView. It is recommended that you now use the Simple Network Management Protocol (SNMP) Application Programming Interfaces (APIs) for your automation needs.

  • If you previously used the System Automation for OS/390 product, you must now use Version 2.2 or later. This will allow you to define an automation policy for SNMP APIs rather than a policy for SNA Operations Management commands.

  • If you directly used the SNA Operations Management commands on NetView, you must now use an SNMP agent and the SNMP APIs for systems automation management.

For detailed information on the SNMP APIs commands and environment requirements, see zSeries Application Programming Interfaces (SB10-7030). For more information on the SNA Operations Management command support that is not offered on z890, see Managing Your Processors (GC38-0452). Both publications are available via IBM Resource Link.

TKE 5.0 workstation to enhance security and convenience:

The Trusted Key Entry (TKE) workstation (#0859) and the TKE 5.0 level of Licensed Internal Code (#0855) are optional features on the z9-109. The TKE 5.0 LIC is loaded on the TKE workstation prior to shipment. The TKE workstation offers security-rich local and remote key management, providing authorized persons a method of operational and master key entry, identification, exchange, separation, and update. The TKE workstation supports connectivity to an Ethernet Local Area Network (LAN) operating at 10, 100, or 1000 Mbps. Up to three TKE workstations can be ordered.

Refer also to the Special Features section. Support for an optional Smart Card Reader attached to the TKE 5.0 workstation allows for the use of smart cards that contain an embedded microprocessor and associated memory for data storage. Access to and the use of confidential data on the smart cards is protected by a user-defined Personal Identification Number (PIN).

Enhanced performance assists for z/VM Linux guests

For HiperSockets, FCP, and OSA:

The z990 and z890 servers introduced an important virtualization technology designed to improve the performance of z/VM guest operating systems (such as Linux on System z9) when Queued Direct Input/Output (QDIO) is used. This virtualization technology is designed to allow QDIO interruptions to be passed directly to guests for HiperSockets, Fibre Channel Protocol (FCP), and OSA on the z9-109, z990, and z890 servers.

A complementary virtualization technology is being introduced for z9-109, z990, and z890:

  • QDIO Enhanced Buffer-State Management (QEBSM) - two new hardware instructions designed to help eliminate the overhead of hypervisor interception
  • Host Page-Management Assist (HPMA) - an interface to the z/VM central storage management function designed to allow the hardware to assign, lock, and unlock page frames without z/VM hypervisor assistance

These new hardware assists can allow a cooperating guest operating system to initiate QDIO operations directly to the applicable channel, without interception by z/VM, thereby helping to provide additional performance improvements. Your z990 and z890 servers will require MCL updates. Support is integrated in the z9-109 LIC. The performance assists are provided on the z9-109, z990, and z890, as follows: HiperSockets (CHPID type IQD), all FICON features (CHPID type FCP), and all OSA features (CHPID type OSD). Refer to the Software Requirements section.

FCP point-to-point attachments:

When a FICON feature is configured as CHPID type FCP, IBM now supports the direct attachment of devices (point-to-point connection), without the need for an intermediate Fibre Channel switch or director. Point-to-point connections may be used to access data stored on these devices, and also to IPL an operating system or other standalone program from such a device, using the SCSI IPL feature. The no-charge SCSI IPL feature (#9904) is required to use the SCSI IPL function.

Note: Point-to-point attachment of devices to an FCP channel, including the capability to IPL from such a device, is also planned to be available for z990 and z890 (MCLs required). N_Port ID Virtualization is not supported for point-to-point attachments.

FCP point-to-point attachments are supported on the z9-109, z990, and z890, by the FICON Express2 and FICON Express features (CHPID type FCP), and by z/VM for guest usage and Linux on System z9. Refer to the Software Requirements section.

Reliability, Availability, and Serviceability

Continuing to provide high availability and reliable operation, z890 delivers features for Reliability, Availability, and Serviceability (RAS).

Processor Unit Sparing: Processor Units (PUs) not purchased by or reserved for a client will be available for transparent sparing and no repair action will be initiated as a result. Reserved, but currently unused PUs may be used for sparing but will generate a repair action. Where there are no available PUs, a failure will cause the client to run degraded by one processor until a repair action can be completed.

Coupling Facility Control Code enhanced patch apply: The Coupling Facility Control Code (CFCC) patch apply process has been enhanced to eliminate the need for a power on reset (POR) of the z890 to apply a "disruptive" CFCC patch.

Concurrent capacity upgrade: At planned availability, a z890 can leverage the inherent zSeries Capacity Upgrade on Demand (CUoD) capability to be upgraded via the concurrent addition of additional Processor Units (PUs) and I/O and limited memory upgrades (24 GB to 32 GB increment) with no disruption to current operations. However, while capacity upgrades to the processor itself are concurrent, your software may not be able to take advantage of the increased capacity without performing an Initial Programming Load (IPL).

Sparing for Storage Protect Keys: The robust configuration of the Storage Protect Keys has been enhanced with chip sparing. Already a triple-array with parity protection and voting, the Key structure for z890 has added sparing, similar to Main Memory chip sparing, to further enhance the availability of this critical function.

Failure containment for the Memory Bus Adapter (MBA): Memory Bus Adapters are designed to provide the critical link between the z890 Processor Units and the I/O subsystem. The Model A04 has two MBAs. In the unlikely event of a catastrophic failure of an MBA chip, the z890 is designed to isolate the failure of that chip such that the remaining MBA chip continues to operate. This helps minimize the impact of a failure and allows for scheduling maintenance. These features give the z890 a very impressive RAS structure.

Other Resource Link functions include the use of Forums to collaborate with fellow product owners, links to hardware and software Fixes, hardware and software Problem solving databases, Services for servers, software and solutions, and Tools designed for specific server and software planning, installation, and configuration. Resource Link content includes:

  • Customized Planning Aids - Allow for the planning, arrival, and installation of IBM eServer hardware on order. All that is needed is an order number and the Configuration Control Number (CCN) to access the planning aids that were customized for a specific order. Included in these planning aids are the feature codes that affect the weight, height, power requirements, cooling, and cables necessary for system installation. The aids also provide customized system information for processor codes and descriptions, system power information, frame requirements, cooling requirements, and hardware management console and support element information.

  • Customer Initiated Upgrade (CIU) and On/Off Capacity on Demand (On/Off CoD)-CIU is an IBM Resource Link Web-based solution that enables customers to set up, order, and download microcode for vertical upgrade of process and/or memory. CIU simplifies planning and installation because no IBM service visit is required to perform the upgrade. With the enhancement of On/Off CoD, customers can add or remove temporary computing capacity as needed, to support fluctuating business cycles, matching computing cost with capacity utilization.

  • CHPID Mapping Tool - Downloadable from Resource Link, this tool allows you to map hardware I/O ports on order to your IOCP CHPID definitions. An availability option automatically maps hardware I/O ports to CHPIDs, minimizing single points of failure. Use of this tool is not mandatory, but recommended for all new z890 hardware builds or for upgrades from a z800 to a z890, as well as for making changes to an already installed machine after hardware upgrades that change or increase the number of channels.

  • Fiber Cabling Service - Provides the cabling connectivity necessary for installing your new z890 server. Because IBM offers a wide range of cables and cabling solutions to meet customer requirements for connecting I/O and networks, this cabling service is available through your IBM service representative from Resource Link.

  • Education - Use this no-charge, online education to train and refresh skills at the convenience of your enterprise. Product education includes planning, introduction, getting started, and 'how to' courses. Learn how to use your IBM server products before your server arrives.

  • Library - View, print, or download documents on IBM hardware and software products. These documents include product overviews, user's guides, planning information, parts catalogs, and safety documentation. Also available are product and description documents, which contain high-level descriptions of specific microcode driver and version levels for each machine family, including EC changes for the associated Hardware Management Console and Support Element.

  • Machine Information - View or search for machine information from reports for machines with IBM maintenance agreements. Simply register for machine information on Resource Link and receive authorization to view reports based on machine serial number as well as links to MES content information. The report data is collected from IBM servers on a weekly basis using the Call Home feature, which transmits critical machine data and also detects failures or pending failures.

Product positioning

The IBM z890 is the latest member of the zSeries family. The z890 servers are intended to provide customers with the power and functionality of the latest zSeries product line, with improved granularity in capacity levels that fit their business. The range of the z890 will be positioned to extend up to 2.2 times higher than our z800 server as well as introducing a lower-capacity entry point than the smallest z800. The z890 is intended to support mission critical enterprise server requirements for e-business transaction processing and data management with the flexibility to respond to changing business demands by allowing it to grow in small or large increments - with your business, run multiple applications - with multiple operating systems if needed, and provide all current zSeries functionality, all on a single server. It is a lower entry price platform for customers who want z/Architecture benefits when running new workloads with Linux or z/OS.e, it is ideal for VSE/ESA customers who have growing traditional workloads along with growing Linux e-business applications, it is ideal for Linux and z/VM customers consolidating workloads onto a single zSeries server. In addition, the z890 offers an excellent application development platform for larger customers or Independent Software Vendors (ISVs) requiring 64-bit z/Architecture and advanced functions like a large number of CHPIDs, LPARs, HiperSockets, or FICON channels.

The z890 will provide a cost-effective and flexible server with the ability to help improve application performance, increase the number of users supported, support more transactions, increase scalability, and consolidate workloads beyond what is available on a z800, in a capacity your business requires.

IBM eServer zSeries Application Assist Processor (zAAP)

(#6520) IBM eServer zSeries Application Assist Processor (zAAP)

The zSeries Application Assist Processor (zAAP) planned to be available on the zSeries 990 (z990) and the zSeries 890 (z890) servers, is an attractively priced specialized processing unit that provides an economical Java execution environment for customers who desire the traditional Qualities of Service and the integration advantages of the zSeries platform.

When configured with central processors (CPs) within logical partitions (LPARs) running z/OS or z/OS.e, zAAPs may help increase CP productivity and may contribute to lowering the overall cost of computing for z/OS and z/OS.e Java technology-based applications. zAAPs are designed to operate asynchronously with the CPs to execute Java programming under control of the IBM Java Virtual Machine (JVM). This can help reduce the demands and capacity requirements on CPs which may then be available for reallocation to other zSeries workloads.

The IBM JVM processing cycles can be executed on the configured zAAPs with no anticipated modifications to the Java applications. Execution of the JVM processing cycles on a zAAP is a function of the Software Developer's Kit (SDK) 1.4.1 for zSeries, z/OS and z/OS.e V1.6, and Processor Resource/Systems Manager (PR/SM).

The amount of CP savings will vary based on the amount of Java application code executed by zAAPs. This is dependent upon the amount of Java cycles used by the relevant applications and on the zAAP execution mode selected by the customer.

Execution of the Java applications on zAAPs (#6520), within the same z/OS or z/OS.e SMP LPAR as their associated database subsystems, can also help simplify the server infrastructures and improve operational efficiencies. For example, use of zAAPs could reduce the number of TCP/IP stacks, firewalls, and physical interconnections (and their associated processing latencies) that might otherwise be required when the application servers and their database servers are deployed on separate physical server platforms.

IBM does not impose software charges on zAAP capacity. Additional IBM software charges will apply when additional CP capacity is used.

Customers are encouraged to contact their specific ISVs/USVs directly to determine if their charges will be affected.

  • Minimum: None.
  • Maximum: Two.
  • Prerequisites: For each zAAP engine installed there must be a corresponding CP engine permanently purchased and installed.
  • Corequisites: None.
  • Compatibility Conflicts: None.
  • Customer Setup: No.

(#0993) ICB-3 link

The Integrated Cluster Bus-3 (ICB-3) link is a member of the family of Coupling Link options. ICB-3 supports a link data rate of 1 GByte per second and is used by coupled servers to pass information back and forth over high speed connections in a Parallel Sysplex environment when the distance between servers is no greater than 7 meters (23 feet). See the cable order section below. ICB-3 is used to connect z800, z900, z890, and z990 servers (2066, 2064, 2086 2084) to z890 servers. Even though ICB-3 is supported for connection to z890 and z990, the recommended ICB connection to these servers is ICB-4. ICB-3s (CHPID type CBP) can be defined as a spanned channel and can be shared among LPARs within and across LCSSs.

There is an STI-3 card (#3993) which resides in the I/O cage to support the ICB-3 connections. The STI-3 card converts the STI input into two 1 GByte/sec ICB-3 outputs. One ICB-3 feature is required for each end of the link. If the ICB-3 feature already exists on the other server, it does not need to be reordered.

  • Minimum: None. At least one I/O feature or Coupling Link feature must be present in a server - ESCON/FICON or ICB/ISC.
  • Maximum: 16 ICB-3 links, 8 STI-3s with two ports on each STI-3 distribution card.
  • Prerequisites: None.
  • Corequisites: STI-3 #3993. ETR #6154. An ICB-3 feature is required for each end of the link.

A 10 meter (33 feet) ICB-3 cable (#0227) is used with the ICB-3 link -- 3 meters (10 feet) is used for internal pathing and strain relief and 7 meters (23 feet) is available for server-to-server connection. Existing 10 meter ICB-3 cables can be reused. This cable is unique to ICB-3. See #0227 ICB-3 cable below.

(#3393) ICB-4 link

The Integrated Cluster Bus-4 (ICB-4) link is a member of the family of Coupling Link options. ICB-4 operates at STI speeds, and like ICB-3, it is used by coupled servers to pass information back and forth over high speed connections in a Parallel Sysplex environment when the distance between servers is no greater than 7 meters (23 feet). See the cable order section below. ICB-4 is a "native" connection used between z890s or between z890 and z990. This is the recommended connection between z890s and z990s. ICB-4s (CHPID type CBP) can be defined as a spanned channel and can be shared among LPARs within and across LCSSs.

An ICB-4 connection consists of one link that attaches directly to an STI port in the server, does not require connectivity to a card in the I/O cage, and provides one output port to support ICB-4 to ICB-4 connectivity. One ICB-4 connection is required for each end of the link.

  • Minimum: None. At least one I/O feature or Coupling Link feature must be present in a server; ESCON/FICON or ICB/ISC.
  • Maximum: 8 ICB-4 links. There is one link on each ICB-4.

This cable is unique to ICB-4. See #0228 ICB-4 cable below.

(#0217, #0218, #0219) InterSystem Channel-3 (ISC-3)

The InterSystem Channel-3 (ISC-3) feature is a member of the family of Coupling Link options. An ISC-3 feature can have up to four links per feature. With the introduction of Server Time Protocol (STP), the ISC-3 feature can be used to transport both Coupling Facility (CF) and STP messages over 2 Gigabits per second (Gbps) links in a Parallel Sysplex environment.

The ISC-3 feature is compatible with ISC-3 features on z9 EC, z9 BC, z990, z890, z900, and z800 servers. While ICB-3 and ICB-4 are used for short distances between servers (7 meters - 23 feet), ISC-3 supports an unrepeated distance of up to 10 kilometers (6.2 miles) between servers when operating at 2 Gbps. Extended distance for ISC-3 is available through RPQ. ISC-3 (CHPID type CFP - peer) can be defined as a spanned channel and can be shared among LPARs within and across LCSSs.

The ISC-3 feature is composed of a Mother card (ISC-M #0217) and two Daughter cards (ISC-D #0218). Each daughter card has two ports or links, for a total of four links per feature. Each link is activated using Licensed Internal Code, Configuration Control (LICCC) with ISC links (#0219). The ISC-D is not orderable. When the quantity of ISC links (#0219) is selected, the appropriate number of ISC-Ms and ISC-Ds is selected by the configuration tool. Additional ISC-Ms may be ordered up to the maximum of ISC-Ds required or twelve (12), whichever is the smaller number. The link is defined in peer (CHPID type CFP) mode only. Compatibility mode is not supported.

Each link utilizes a Long Wavelength (LX) laser as the optical transceiver, and supports use of a 9 micron single mode fiber optic cable terminated with an industry standard small form factor LC Duplex connector. The ISC-3 feature accommodates reuse (at reduced distances) of 50 micron multimode fiber optic cables when the link data rate does not exceed 1 Gbps. A pair of Mode Conditioning Patch cables are then required, one for each end of the link.

  • Minimum: None. Links are ordered in increments of one. It is recommended that initial orders include two links. At least one I/O feature (ESCON or FICON) or Coupling Link feature (ICB or ISC-3) must be present in a System z9.
  • Maximum: 12 features, 48 links (4 links per feature).
  • Prerequisites: None.
  • Corequisites: ETR feature (#6155) or Server Time Protocol (STP) feature (#1021). If a 9 micron single mode fiber optic cable terminated with an SC Duplex connector is being reused, a 9 SM LC to SC Duplex Conversion Kit may be needed.
  • Compatibility Conflicts: The ISC-3 feature has an optical transceiver that supports an LC Duplex connector only. A single mode fiber optic cable with an SC Duplex connector is not supported with this feature.
  • Customer Setup: No.
  • Limitations:
    • The maximum number of Coupling Links combined (ICs, ICB-3s, ICB-4s, and active ISC-3 links) cannot exceed 64 per server.
    • The unrepeated distance between 2 Gbps ISC-3 links is limited to 10 kilometers (6.2 miles). If greater distances are desired, an RPQ request should be submitted.
  • Field Installable: Yes.
  • Cable Order: A customer-supplied 9 micron single mode fiber optic cable terminated with an LC Duplex connector is required for ISC-3. This cable may also be used to carry STP traffic. In the event that the target link does not support an LC connector, a 9 SM LC to SC Duplex Conversion Kit may be needed. If 50 micron multimode fiber optic cables are being reused with the ISC-3 feature, a pair of Mode Conditioning Patch (MCPs) cables are required, one for each end of the link. MCP cables are only supported for 1 Gbps links.

(#1021) Server Time Protocol (STP)

STP, which provides a similar timing function to ETR, changes the current rule for ETR that requires feature code 6155 (ETR) to be configured when an ISC or ICB feature is ordered.

  • Limitations: STP requires a Next Generation HMC and z/OS V1.7 with PTFs.

Cables for ICB links

(#0227) ICB-3 cable

The Integrated Cluster Bus-3 (ICB-3) cable is a unique 10 meter (33 feet) copper cable to be used with ICB-3 links (#0993). With the introduction of Server Time Protocol (STP), the ICB-3 feature can be used to transport both Coupling Facility (CF) and STP messages over 1 GigaByte per second (GBps) links in a Parallel Sysplex environment. Existing 10 meter ICB-3 cables can be reused.

ICB-3 cables are automatically ordered to match the quantity of ICB-3 links (#0993) on order. The quantity of ICB-3 cables can be reduced, but cannot exceed the quantity of ICB-3 links on order.

(#0228) ICB-4 cable

The Integrated Cluster Bus-4 (ICB-4) cable is a unique 10 meter (33 feet) copper cable to be used with ICB-4 links (#3393). With the introduction of Server Time Protocol (STP), the ICB-4 feature can be used to transport both Coupling Facility (CF) and STP messages over 2 GigaByte per second (GBps) links in a Parallel Sysplex environment. Existing 10 meter ICB-4 cables can be reused.

ICB-4 cables are automatically ordered to match the quantity of ICB-4 links (#3393) on order. The quantity of ICB-4 cables can be reduced, but cannot exceed the quantity of ICB-4 links on order.

When connecting a non-raised-floor z9 BC to a z890 using ICB-4, an ICB-4 Cable for NRF (#0232) is needed.

Note: When ordering ICB cables, planning for the required number of cables should consider the total number of servers and ICB features to be ordered and enabled in calculating the number of cables to be ordered. As an example, if two servers with four features are being ordered and enabled, the total number of cables required is two. Proper planning will prevent over-ordering the number of cables.

  • Limitations: While the ICB-4 cable is 10 meters in length, 3 meters (10 feet) is used for internal routing and strain relief - 7 meters (23 feet) is available for server-to-server connection.

Attaching the Sysplex Timer to the zSeries 890

(#6154) ETR feature

The External Time Reference (ETR) feature is optional, supports attachment to the Sysplex Timer (9037) at an unrepeated distance of up to three kilometers (1.86 miles) and a link data rate of 8 Megabits per second. The ETR feature utilizes 62.5/125 micrometer multimode fiber optic cabling terminated with an MTRJ connector. The Sysplex Timer is the centralized time source that sets the Time-Of-Day (TOD) clocks in all attached servers to maintain synchronization. The Sysplex Timer provides the stepping signal that helps ensure that all TOD clocks in a multiserver environment increment in unison to permit full read/write data sharing with integrity. The Sysplex Timer is a key component of an IBM Parallel Sysplex environment and a Geographically Dispersed Parallel Sysplex (GDPS) e-business availability solution.

The ETR features do not reside in the I/O cage and do not require connectivity to a card in the I/O cage.
