Overview

The newest additions to the IBM eServer z800 family of servers consist of eight general-purpose models and a Coupling Facility only model.

The z800 family uses key functional characteristics of IBM eServer z900 in a package that delivers excellent price/performance for those requiring zSeries functionality with total capacity less than that currently offered by the z900. The z800 is intended to provide a transition into the new world of e-business servers exploiting z/Architecture, and is intended to take full advantage of the IBM Framework for e-business. These new models of the z800 family, along with the IBM eServer zSeries Offering for Linux announced on January 29, 2002, which uses the z800 0LF model as its foundation, and the new z/OS™.e operating system software being announced today, are intended to satisfy mission-critical enterprise server requirements for e-business transaction processing and data management with the same qualities of service as the IBM eServer z900 while helping customers to exploit the fast-growing world of e-business and new workload data management applications on the IBM eServer z800. These new models of the z800 family, when used in concert with the IBM Framework for e-business, are designed to help you build the innovative infrastructure required for the transition into the new world of e-business.

z800 is:

  • An ideal lower-entry-point, new workload platform for those who want the zSeries qualities of service using Linux or z/OS.e
  • Ideal for VSE customers who have growing traditional S/390® workloads, have growing new Linux workloads due to e-business applications or server consolidation, or are migrating to z/OS
  • Ideal for z/VM™ customers who want to consolidate Linux workloads onto a single zSeries server or who require support for varied operating system environments
  • An excellent choice to meet the application development needs of those who require a 64-bit target platform

A new optional offering introduced January 29, 2002, IBM Network Integration and Deployment Services for zSeries Fiber Cabling, is also available on z800 servers. The zSeries Fiber Cabling Service is intended to provide personalized, scalable, flexible cabling options for the z800 to support your current system environment, with the future in mind.

Also being announced today is zSeries Entry Licensing Charge (zELC), a new, attractive software pricing structure for the z800.

Performance for Your e-business Advantage

The IBM eServer z800 brings 64-bit architecture capability and key functional characteristics of the IBM eServer z900 to customers requiring zSeries functionality with total capacity less than z900.

The IBM eServer z/800 combined with z/OS.e is intended to bring increased flexibility, choice, and capacity to you for adding new workloads and for running a mix of new and traditional work. A few examples of the potential capacity increases available to you are:

  • The z/800 Model 001 is expected to support up to 25% more SAP throughput or up to 25% more Lotus Notes® users as compared to the G5 9672 Model T16.
  • The z/800 Model 001 is expected to support up to 25% more throughput in Web-based transactions as compared to the G5 9672 Model T16. IBM's eServer z/800, with its z/Architecture, is expected to enable additional transactions to be executed, and, with the workload manager part of z/OS.e or z/OS in combination with balanced hardware, it is also expected to be well suited to contain and manage the spikes generated by Web transactions.

64-bit architecture, compared with the architecture available on many of the systems currently in use in this performance range, should offer improvements beyond those stated below for the processor comparisons. Not all comparisons are listed here. For more detailed information, including Large System Performance Reference (LSPR) information, contact your IBM representative.

When comparing the z800 family to many of the currently used systems in the same performance category, the following performance improvements may be possible:

  • Improvements in batch elapsed time through the use of FICON™ Express
  • Performance improvements for data compression and Crypto functions

Performance Processor Comparison Estimates with OS/390® Version 2 Release 10: Compared to some of the 9672 Generation 4 servers, the z800 server is expected to offer the following performance advantage:

   2066-0A1   1.1 -- 1.4   times 9672-R15
   2066-0B1   1.6 -- 2.0   times 9672-R15
   2066-0C1   1.7 -- 2.4   times 9672-R15
   2066-0A2   1.9 -- 2.4   times 9672-R25
   2066-0A2   1.3 -- 1.7   times 9672-R35

Relative to the following 9672 G5 models, the expected performance of the selected z800 server models is:

   2066-0A1   0.9 -- 1.0   times 9672-RA6
   2066-0B1   1.2 -- 1.4   times 9672-RA6
   2066-0C1   1.1 -- 1.3   times 9672-R16
   2066-001   1.4 -- 1.7   times 9672-T16
   2066-0A2   1.0 -- 1.3   times 9672-R26
   2066-002   0.9 -- 1.2   times 9672-R36
   2066-003   1.0 -- 1.3   times 9672-R46
   2066-004   1.1 -- 1.3   times 9672-R56

Relative to the following MP3000 servers, the expected performance ratios to selected z800 server models is:

   2066-0A1   1.2 -- 1.5   times 7060-H30
   2066-0B1   0.9 -- 1.1   times 7060-H50
   2066-0A2   1.1 -- 1.3   times 7060-H70

The above performance estimates are Internal Throughput Rate Ratios (ITRR) based on measurements and projections using standard IBM benchmarks in a controlled environment and are subject to change without notice. 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. Such performance estimates are provided "AS IS" and no warranties or guarantees are expressed or implied by IBM. Software licenses that are based on machine performance will be billed based on these estimates until such time that IBM determines and publishes final performance measurements, at which time appropriate billing adjustments may be made as determined by IBM.

For more detailed performance information, including Large System Performance Reference (LSPR) information, contact your IBM representative.

Technical Description/High-Level Design

The z800 is a stand-alone single-frame package, designed such that all of the system configurations fit into one frame. The z800 frame holds the following subsystems:

  • Processor Subsystem
  • I/O Subsystem
  • Power, Packaging, and Cooling Subsystem
  • Service Element Subsystem

Processor Subsystem: The Processor Subsystem for the z800 is provided on one unique building block, the Basic Processor Unit (BPU) card, which is similar to the processor card in the Multiprise 3000. The processor MCM carries five Processor Unit chips, memory, and optional Cryptographic Co-processors.

I/O Subsystem: The I/O Subsystem of the z/800 supports the new I/O features common with the z/900 and provides a plugging capability for up to 16 I/O Books integrated in the frame.

  • Channels: 16-Port ESCON, FICON Express
  • OSA-Express, Gb Ethernet, Fast Ethernet, Token Ring, 155-ATM
  • PCI Cryptographic Coprocessor (PCI-CC), and PCI Cryptographic Accelerator (PCI-CA)
  • Coupling links: ISC-3 (CFP)

The system provides hot plug and concurrent upgrade/repair capabilities for these attachments, just as in the z900. FICON Express hardware provides native FICON or FICON Bridge support.

Power Packaging and Cooling (PPC) Subsystem: The PPC Subsystem provides the mechanical, power, and cooling support for the z800 system as a dense, cost-efficient, self-contained package for entry offerings.

Service Element (SE) Subsystem: The SE Subsystem is based on IBM's standard SE design of the z900 server family, also packaged on a ThinkPad® inside the frame. Just like the z900, two SEs are standard on the z800 and the z800 system requires a connection to a Hardware Management Console. The code package includes a Repair & Verify package with online guided repair procedures.

ESAME 64-bit Architecture: ESAME is a 64-bit architecture mode that is a superset of ESA/390. The ESAME architecture was first exploited in the z900 and is now available to customers requiring zSeries functionality with total capacity less than that currently offered by the z900.

ESAME has:

  • 64-bit general registers.
  • New 64-bit integer instructions. Many ESA/390 instructions with 32-bit operands have new 64-bit and 32-to-64-bit analogs.
  • New 64-bit branch instructions. 64-bit addressing is supported for both operands and instructions.
  • 64-bit address generation. ESAME provides 64-bit virtual addressing in an address space, and 64-bit real addressing. Addressing is expanded from 2 gigabytes to 16 exabytes.
  • Exploitation of access registers to allow use of 2K multiple 64-bit address spaces.
  • 64-bit control registers. ESAME control registers can specify regions or segments, or can force virtual addresses to be treated as real addresses.
  • An expanded prefix area, from 4K to 8K bytes.
  • New instructions that provide quad word storage consistency.

The 64-bit I/O architecture offers an Indirect Address List, which allows all programs to designate data addresses for I/O. Use of 64-bit operands and general registers for all I/O instructions is added. Gigabit Ethernet architecture is expanded to allow 64-bit Queued I/O queuing structures, in addition to the 64-bit Indirect Addressing List for data addresses for I/O. IEEE Floating Point architecture adds 12 new instructions for 64-bit integer conversion. The Coupling architecture allows CFCC to drive the ISC3 and ICB3 channels and allows full CFCC 64-bit addressing. 64-bit addressing CFCC can be loaded into VM guest storage. The 64-bit SIE architecture allows an ESAME host to have an ESA/390 or ESAME guest. Zone Relocation is expanded to 64-bit for LPAR and z/VM. Use of 64-bit operands and general registers for all Crypto Coprocessor instructions and PCI Crypto instructions is added.

Hardware Offering Assumptions

Multi Chip Module (MCM): The MCM Part Number is fully populated with five Processor Units. Model granularity is delivered via Licensed Internal Code Control Code (LICCC). The largest model (4+1) does not include a spare PU, similar to G5 and G6 offerings but different than the z900.

Memory: Minimum physical memory is 8 GB with additional offerings of 16 GB, 24 GB, and 32 GB in 8 GB increments. The z800 also contains one keystore DIMM, which will support all memory configurations. Each DIMM pair is a Field Replaceable Unit (FRU).

Cryptography (Crypto): The Crypto coprocessor hardware is optional on the z800. Two Crypto chips (packaged as SCMs) can be plugged onto the processor card. The Crypto SCMs are FRUs which can be plugged in the field. The PCI-Crypto cards, PCI-CC and PCI-CA, are available on all eight general-purpose models. PCI-CA only is available on the Linux only model (0LF). The Crypto coprocessor is a prerequisite for the PCI-CC and PCI-CA.

Balanced utilization of all hardware cryptographic engines is the key to the performance achievements of zSeries servers. z/OS transparently routes requests for cryptographic services to an appropriate, available engine and in the case of Secure Sockets Layer (SSL) transactions, cryptographic requests are load-balanced across all available engines, taking maximum advantage of zSeries scalability.

z800 cryptographic functions are intended to include the full range of cryptographic operations used for e-business, e-commerce, and financial institution applications.

Configuration Capabilities: The Channel Subsystem provides six 1 gigabyte/second STI links for I/O and Coupling Facility connectivity. Of these six I/O domains, four can have their Gigabyte STI links be multiplexed to four 333 megabyte/second I/O slots. These 16 I/O slots are intended to provide ample I/O connectivity capabilities. Each of these slots can drive one of the new I/O features common with the z/900 (15-ESCON, FICON Express, OSA-E channels, and so on) such that 240 ESCON channels can be provided. The remaining two I/O domains can be used to drive ICB Peer CF links (CBP), IC links (ICP), and other devices that require CHPID numbers.

Geographically Dispersed Parallel Sysplex™ (GDPS™): The IBM eServer z800 is intended to support the GDPS in the same way the IBM eServer z900 does.

In e-business, two of the most stringent demands for survival are continuous availability and near-transparent disaster recovery (D/R). Systems that deliver continuous availability combine the characteristics of high availability and continuous operations to deliver high levels of service (24x7x52). To attain the highest levels of continuous availability and near-transparent D/R, the solution should be based on geographical clusters and data mirroring. These technologies are the backbone of the GDPS solution.

Since IBM Parallel Sysplex® clustering technology enables resource sharing and dynamic workload balancing, enterprises are now able to dynamically manage workloads across multiple sites to achieve high levels of availability. GDPS complements a multisite Parallel Sysplex implementation, and is intended to provide a single, automated solution to dynamically manage storage subsystem mirroring (disk and tape), processors, and network resources to allow a business to attain continuous availability and near-transparent business continuity (disaster recovery) without data loss. GDPS is intended to minimize and potentially eliminate the impact of any failure, including disasters or a planned outage. It is intended to provide the ability to perform a controlled site switch for both planned and unplanned site outages, with no data loss, maintaining full data integrity across multiple volumes and storage subsystems and the ability to perform a normal Data Base Management System (DBMS) restart — not DBMS recovery — at the opposite site. GDPS is application independent (covers your complete application environment) and supports both the synchronous (PPRC) as well as the asynchronous (XRC) forms of remote copy.

GDPS is intended to provide the following functions:

  • PPRC and XRC configuration management, which automates the management of the remote copy infrastructure
  • Planned reconfiguration support, which automates operational tasks from a single point of control
  • Unplanned reconfiguration support, which automates recovery from a z/OS, OS/390, software subsystem, processor, Coupling Facility, storage subsystem, or site failure
  • Automatic enablement of Capacity Back Up (CBU)
  • FlashCopy exploitation
  • Coupled XRC (CXRC) support
  • Peer to Peer Virtual Tape Server support
  • Management of Linux for zSeries images

For a more detailed description of GDPS, refer to the white paper available at:

Coupling Considerations: The z800 system includes the technology intended to support Parallel Sysplex environments. If z800 systems are coupled with other z800 or z900 systems in a Parallel Sysplex cluster, it is recommended that Peer Mode ISC or ICB (CFP, CBP) links be configured for the coupling links.

Coupling connections to non-z/Architecture systems such as G5 and G6 servers can be provided via the ISC-3 (CFP) links configured as Compatibility Mode (CFS, CFR) links, if necessary. There will be no ICB Compatibility Mode links offered.

The z800 also supports the Internal Coupling links (ICP) for connectivity to Coupling Facilities within the same server.

The required external time reference (ETR) for Parallel Sysplex is provided via an ETR connection to a Sysplex Timer® via an OSC/ETR card (which contains one port per card). This connection is included in the optional zSeries Fiber Cabling Service.

The 0CF Coupling Facility models of the z800 are intended to initially support the Coupling Facility Control Code (CFCC) level 12, which includes 64-bit addressing, thus eliminating the 2 GB control store limit.

Clustering Architecture — The Intelligent Resource Director: Several architecture features are provided that enable the z/OS Workload Manager (WLM) to interact with the I/O Supervisor and with the channel subsystem which is intended to provide more efficient use of the system's resources. These new facilities allow the central processors, channels, and associated DASD I/O resources to be managed by z/OS WLM on a policy basis for the LPARs within the cluster. They are intended to provide z/OS WLM with the ability to dynamically interact with PR/SM™ in order to control the use of CPU and channel path resources within the Intelligent Resource Director. Additionally, they allow z/OS WLM to prioritize the execution of queued I/O operations at the channel subsystem.

LPAR CPU Management: This architecture facility is intended to provide z/OS WLM with the ability to dynamically alter the logical partition (LP) weights for each of the logical partitions within the LPAR cluster, thereby influencing PR/SM to help each logical partition receive the percentage of shared CPU resources necessary to meet its workload goals.

Dynamic Channel Path Management (DCM): These interfaces allow z/OS WLM to dynamically reconfigure channel path resources within the cluster and are intended to help ensure that a business-critical application's I/O processing requirements, necessary to meet its workload goals, are not being delayed due to the unavailability or overutilization of channel path resources.

Channel Subsystem Priority Queuing: This facility provides z/OS's WLM with the ability to prioritize and thereby influence the channel subsystem's execution of queued I/O requests. The benefit is intended to ensure that the most important I/O across all LPARs will be handled before less important I/O requests that are waiting to use some channel.

Performance: The performance design of the z/Architecture helps to enable the entire server to support a new standard of performance for all applications by expanding upon the balanced system approach. As CMOS technology has been enhanced to support additional processing power and more engines, the IBM eServer z800 was designed to support the increase in processing power. The I/O subsystem supports greater bandwidth through the use of FICON Express and associated DASD, thus providing for larger and quicker data movement into the server. Support of larger amounts of data within the server required improved management of storage configurations made available through combination of the software operating system and hardware support of 64-bit for real and virtual storage. New coupling links in the architecture allow customers to continue to exploit the advantage of the leading clustering solution in the industry, Parallel Sysplex. The combined balanced system effect allows for dramatic increases in performance across a broad spectrum of applications.

Subchannel Constraint Relief: As users see their I/O configurations grow, and in order to meet the high storage and high availability demands of their workloads, they must define more and more devices and subchannels to their system. Moreover, users that exploit the Parallel Access Volumes (PAV) or Peer-to-Peer Remote Copy features, including the PPRC Dynamic Address Switching (P/DAS) capability, of the IBM Enterprise Storage Server™ may require additional subchannel growth for improved performance and continuous availability.

The z800 supports 512K HSA subchannels, the maximum for all logical partitions (LPs) and up to 63K in basic mode and for each logical partition (LP) in LPAR mode.

Capacity Upgrade on Demand (CUoD): Improving on IBM's G6 CUoD capability, the z800 offers more flexible concurrent upgrades. If an installation projects that their present capacity would be satisfied by a small z800 model, but envisions growth to a larger model, CUoD allows concurrent upgrade capability. By planning ahead, your installation can react quickly to increased capacity demands.

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

Network Connectivity — OSA-Express Features: The Open Systems Adapter-Express (OSA-Express) features in combination with the z800 continue to offer you an open platform delivering integrated, direct connectivity to the Local Area Network (LAN) and Asynchronous Transfer Mode (ATM) network, intended to reduce overhead and latency and to continue to reduce the total cost of computing across your enterprise.

The dual-port OSA-Express features support the Gigabit Ethernet, Fast Ethernet, ATM, and Token Ring environments and are all capable of achieving line speed. Results will vary depending upon customer environment and applications.

All of the OSA-Express features can be configured to utilize Queued Direct Input/Output (QDIO), a highly efficient data transfer architecture that breaks many of the barriers associated with the Channel Control Word (CCW) architecture. QDIO supports TCP/IP environments only.

The OSA-Express Fast Ethernet, ATM, and Token Ring features can also be configured to support non-QDIO environments, either TCP/IP passthru (LCS — LAN Channel Station) or Systems Network Architecture/Advanced Peer-to-Peer Networking®/High Performance Routing (SNA/APPN®/HPR) environments.

The software requirements for the OSA-Express features are dependent upon the operating mode and media type. Refer to the Software Requirements section of this announcement, or to the Open Systems Adapter-Express Customer's Guide and Reference (SA22-7476).

HiperSockets: The HiperSockets function provides "Network in the Box" functionality that allows high-speed any-to-any connectivity among OS images within a zSeries server without requiring any physical cabling. This "Network in the Box" concept minimizes network latency and is intended to maximize bandwidth capabilities between z/VM, Linux, and z/OS images (or among combinations of these) to enable optimized e-business and ERP solutions within a single server. Up to four separate "Cluster LANs" can be configured within a server, thereby allowing OS images to be grouped according to the function they provide. These groupings are independent of sysplex affiliation.

Performance is drastically improved over the currently available OSA-Express Gigabit LPAR to LPAR latency, depending upon the workload characteristics. The z800 does a direct move from one LPAR's memory to another's memory using QDIO.

I/O — CHPIDs Assignment: The ability to assign channel paths IDs independent of the installed physical position that channel cards have within the I/O cage is a Customer Engineer-only function on the z800 Support Element that allows the active channels to be assigned CHPID numbers chosen by you. All 256 CHPID numbers may be assigned; no more "blocked CHPIDs."

Availability Mapping Tool: A Web-based tool is available through IBM's Resource Link to enable an installation to remap CHPID assignments after the server is ordered, but before it is installed. If you want to remap CHPID numbers at install time, this tool must be used to create a diskette to be provided to the install team. The tool can also optionally aid an installation in choosing channels for control units that best exploit the reliability, availability, and serviceability characteristics of the system.

Inter-System Channel (ISC-3), Integrated Cluster Bus (ICB-3), and Internal Coupling Channel (IC-3): To help ensure Sysplex environments continue to scale with today's efficiency as IBM eServer zSeries performance grows, the zSeries coupling link design has been improved. To optimize z800 performance either between other IBM eServer zSeries servers, or among S/390 Parallel Enterprise Servers, two modes of coupling links are now available: Peer Mode and Compatibility Mode.

  • Peer Mode supports coupling between IBM eServer zSeries servers and provides benefits of both sender and receiver capability on the same link for reduced link requirements, increasing the amount of buffer sets (subchannels) from 2 to 7, 64 KB data buffers for performance improvements with large messages, protocol changes for better performance, and increased link capacity.

    With these design improvements, the Peer Mode ISC-3 (CFP) connections perform at 200 MB/sec for distances less than 10 km (compared to 100 MB/sec in Compatibility Mode) and, with an RPQ, at 100 MB/sec up to 20 km. Peer Mode ICB-3 (CBP) connections perform at a peak capacity of up to 1000 MB/sec, although effective data rates would be approximately 20% slower. Peer Mode Internal Coupling links (ICP) provide an effective data transfer rate of 1250 MB/sec for connectivity to coupling.

  • ISC-3 links support Compatibility Mode between zSeries and S/390 Parallel Enterprise Servers, or between IBM eServer zSeries servers. ICB-3 are the only ICB links supported on the z800, and thus can be configured only with other IBM eServer zSeries servers.

z800 servers support a maximum of 24 ISC-3 links; five ICB-3 links on a general-purpose z800; or six ICB-3 links on the 0CF model. The z800 general-purpose models and 0CF model also allow the definition of up to 32 internal coupling (IC-3) links.

It is not possible to get the maximum ISC-3 (24) and ICB-3 (5 or 6) on the same machine. Following are examples of combinations that are possible:

  • 24 ISC-3 plus 2 ICB-3
  • 18 ISC-3 plus 3 ICB-3
  • 12 ISC-3 plus 4 ICB-3
  • 6 ISC-3 plus 5 ICB-3

64-bit Architecture (with z/OS): 64-bit architecture is intended to eliminate bottlenecks associated with lack of addressable memory by making the addressing capability nearly unlimited (up to a theoretical 16 exabytes; this limit compares to the prior capability of 2 Gbytes in S/390 systems). As an application's server capacity requirements grow, the requirement for greater addressability increases as well. As addressability begins to be constrained, the lack of real storage increases overhead and ultimately constrains system growth. This situation exacerbates critical situations in which explosive systems growth has been a result of successful e-business implementation.

IBM's zSeries 64-bit architecture is intended to:

  • Enable optimal use of memory resources
  • Provide for migration flexibility
  • Use a single level of operating system for both S/390 and zSeries servers, across the entire enterprise
  • Allow nondisruptive testing and migration and provide for ease of transition for systems support staff
  • Ensure maximum transparency to the operating system and complete transparency to system applications

64-bit Addressing — Memory Constraint Relief: The z800 provides up to 32 GB memory and enables significant paging overhead reduction. 64-bit real addressing is intended to give immediate constraint relief to customers with real memory bottlenecks today. This is intended to benefit DB2®, Domino™, TSO, and other UNIX®-based applications.

z800 Support for Linux: The zSeries Offering for Linux offers a comprehensive server environment for multiple Linux systems on a single z800 server. zSeries Offering for Linux is an easy-to-use, high-performance Linux Offering which has the capability to have one to four enabled engines.

The S/390 Integrated Facility for LINUX previously announced for 9672 Parallel Enterprise Servers, G5 and G6, and also for IBM eServer z900 is also available on z800. This feature provides the ability for an independent processing capacity for Linux applications. An installation may purchase additional processing capacity, exclusively for Linux workloads, with no effect on the z800 model designation. No additional IBM operating system or middleware charges will be incurred due to the additional capacity unless the software is actually running in that additional capacity. The hardware feature is isolated from general use, is dedicated for Linux use only, and cannot run other IBM operating systems except z/VM Version 4.

IBM continues to support a full complement of middleware for Linux on zSeries.

New Hardware Functions and Capabilities with the IBM z800: In addition to the traditional functions of S/390 servers, the z800 provides:

  1. Enhanced Storage Protect Keys

    The z800 has enhanced the memory storage protect key design by adding a third key array to the keystore DIMM. The arrays are parity checked and employ a Triple Voting strategy to assure accuracy.

  2. ESCON Port Sparing

    The new ESCON 16-port I/O card is delivered with one unused port dedicated for sparing in the event of a port failure on that card. Other unused ports are available for nondisruptive growth of ESCON channels.

  3. Concurrent Maintenance/Upgrade for Coupling

    The z800 introduces concurrent maintenance for the ISC-3 adapter card. Also, coupling links may now be added concurrently when the new receiver or peer-mode coupling links have been predefined in the IOCDs, prior to an IML. This eliminates the need for scheduled downtime in the demanding sysplex environment.

  4. Crypto Coprocessors

    The Cryptographic Coprocessor is optional on the z800. Two Crypto chips (packaged as SCMs) can be plugged onto the processor card. The Crypto SCMs are FRUs which can be plugged in the field.

  5. Concurrent Service for I/O Cards

    All cards that plug into the I/O cage are able to be added and replaced concurrent with system operation to eliminate any need for scheduled outages to service or upgrade the I/O subsystem.

Reliability

Parts integration reduces the number of parts in the machine, which should lead to higher reliability.

A Systems Assurance Pre-Installation Review is required for the first installation in a location. For details, refer to the z800 Systems Assurance Product Review (SAPR) Guide (SA01-007), available via Resource Link:

Availability

The standard features that are intended to provide a high level of availability include:

  • Enhanced Processor Design

    All z800 servers are provided with an enhanced processor design. Each central processor (CP) contains dual Instruction/Execution Units, which operate simultaneously. Results are compared, and in the event of a miscompare, Instruction Retry is invoked. This design is intended to simplify checking, and reduces CP failures due to soft errors.

  • Alternate Support Element (Standard)
  • Fault Tolerant Design

    Fault tolerant design allows hardware recovery to be performed, in most cases, totally transparent to operation and helps reduce the need for a repair action, or defers a repair action to a convenient time scheduled by you.

  • Processor Unit Sparing

    Spare PUs are provided, whenever the configuration allows, to maintain performance levels should an active CP, Integrated Coupling Facility (ICF) feature, System Assist Processor (SAP), or Integrated Facility for Linux (IFL) feature, fail on a z800 server model. The general philosophy is to provide a spare PU whenever possible; that is, when the number of CPs, ICFs, SAPs, and IFLs is less than the total number of PUs available.

    • Sparing is transparent in all modes of operation and requires no operator intervention to invoke a spare PU (if available).

      As a further enhancement, in most cases, the application that was running on the failed CP will be preserved and will continue processing on a new CP with no customer intervention required. Refer to the Enhanced Application Preservation section below.

    • Dynamic SAP Sparing/Reassignment

      Dynamic recovery is provided for failure of the SAP. In the event of a SAP failure, if a spare PU is available, in most cases the spare PU will be dynamically activated as a new SAP. If there is no spare PU available, and the CPC has more than one CP, an active CP will be reassigned as a SAP. In either case, there is no customer intervention required. This capability helps reduce the occurrence of an unplanned outage and can permit a service action, if necessary, to be deferred to a more convenient time.

  • Enhanced Application Preservation

    Application Preservation captures the machine state in the event of a CP failure and will, in most cases, switch processing to a spare PU or another active CP without intervention. This capability helps reduce unplanned outages, helps reduce intervention in the recovery process, and helps to preserve your application processing environment.

  • Dynamic ICF Expansion

    Dynamic ICF Expansion is a function that allows a Coupling Facility (CF) logical partition with dedicated ICF processors to acquire additional processing power from the LPAR pool of shared general-purpose CPs or shared ICFs being used to execute production and/or test work on the system. This function is very useful when the CF logical partition in a z800 general-purpose model backs up another CF. In this event, the CF logical partition, using Dynamic ICF Expansion, can acquire additional processing capacity to handle the full CF workload. Also, Dynamic ICF Expansion can be used to handle a peak workload situation when the CF logical partition is being used as the primary CF. This feature adds considerable flexibility to the configurability of the CF logical partition in z800 general-purpose models and optimizes the use of the processing power in the system.

    The Dynamic ICF Expansion feature is available to every CF logical partition with dedicated ICF processors. Each ICF coupling facility partition has its own ability to specify the number of ICF features that are dedicated to that partition and the amount of additional capability it can acquire. The tradeoff between using ICF features and the CPs in the LPAR shared pool is the exemption from software license fees.

    Dynamic ICF Expansion is available on all z800 general-purpose models.

  • Dynamic CF Dispatching

    The Dynamic CF Dispatching function helps enable continuous computing in the event of a CF failure without requiring a stand-alone backup CF. Enhanced dispatching algorithms help you to define a backup CF in a logical partition (LPAR) on your system. While this logical partition is in backup mode, although it is sharing resources with other LPARs running other active workload, it uses very little processor resource. When the backup CF becomes active, only the resource necessary to provide coupling is allocated.

  • Error Correction Code (ECC)

    Memory error checking and correction code is intended to detect and correct single bit errors. Also, because of the memory structure design, errors due to a single memory chip failure are corrected.

  • Dynamic Memory Sparing

    Memory DIMMs are equipped with spare memory chips. During normal operations, the system monitors and records accumulation of failing bits in memory chips that are corrected by ECC. Before a failure threshold is reached, which could result in an error that cannot be corrected, the system invokes a spare memory chip in place of the one with the accumulated failing bits. This action may prevent an unscheduled outage for replacement of memory DIMMs.

  • LPAR Dynamic Storage Reconfiguration (DSR)

    PR/SM LPAR storage reconfigurations can occur, allowing nondisruptive addition or removal to any partition with a cooperating guest.

  • Enhanced LPAR DSR

    This capability removes the restriction of storage reconfigurations being possible only from an adjacent and above logical partition.

  • Single Storage Pool

    The single storage pool function is provided on z800 general-purpose models. With this function, all physical storage is dynamically designated by LPAR as either central storage or expanded storage as requirements of active logical partitions dictate.

    As a result, the need to predesignate storage as either central storage or expanded storage prior to IML into LPAR mode on the Storage Page of the RESET Profile panel is no longer necessary and is no longer provided. The system programmer now has greater flexibility when planning the division of storage in order to satisfy anticipated logical partition definitions.

    Without this function, a non-optimum designation of storage might be made in order to accommodate a range of logical partition definitions that typically vary from time to time. Single storage pool streamlines the planning effort for any configuration as the need arises. This function aids in the migration from 31-bit OS/390 where logical partitions are, at most, 2 GB of central storage plus optional expanded storage, to 64-bit z/OS, where logical partitions use only central storage and no expanded storage.

  • Subsystem Storage Protect

    Subsystem storage protection and subspace group facility support, for use with CICS/ESA®, prevent application software from overwriting CICS system software, control blocks, and address spaces.

  • Scrubbing

    Storage background scrubbing provides continuous monitoring of storage for the correction of detected faults before the storage is used.

  • Dynamic I/O Configuration

    Dynamic I/O configuration enhances system availability by supporting the dynamic addition, removal, or modification of channel paths, control units, I/O devices, and I/O configuration definitions to both hardware and software without requiring a planned outage.

  • Concurrent Channel Upgrade within the I/O cage

    It is possible to concurrently add ESCON, FICON Express, OSA-Express, and OSA channels and Coupling Facility Links, provided an STI is available and there are unused channel positions and channel adapter cards (for channels) or Coupling Links available. This capability may help eliminate an outage to upgrade the channel configuration.

  • Concurrent Channel Maintenance

    Concurrent channel maintenance allows replacement of a channel card without having to take the system or the channel group down. All CHPIDs on the affected card must be configured offline.

  • Dual Power Feeds

    The power system offers dual primary (ac) power feeds. Each feed is electrically isolated and enables redundant power paths to each server. To take full advantage of the redundant power paths built into the z800, it is necessary to provide dual electrical service to the server to minimize any outage due to a single-path power interruption.

  • Redundant Power Thermal Subsystem

    The ac and dc power subsystems are designed with N+1 redundancy. Failure of a single power thermal component does not need to cause a system outage.

  • Storage Recovery

    z800 servers have error checking and correction of L2 and L3 storage. The servers also have line delete for L1 and L2 Caches and Directories and line relocate for the Caches and L2 Directory. z800 servers perform ECC, background scrubbing, and dynamic sparing of L3, L4 memory, as well as ECC on the system memory buses.

  • External Time Reference (ETR)

    The Sysplex Timer® has been a key element in the Parallel Sysplex® environment since its introduction. It is intended to ensure that multiple z/OS and OS/390 systems can appear as a single system image, synchronizing the Time-of-Day (TOD) clocks of all of the attached systems, helping to ensure a consistent time stamp. When multiple systems update the same database, all updates are time-stamped in sequence.

    The ETR function is now standard on zSeries. There are two ETR cards located in the CEC cage, each with a fiber optic connection to provide the capability to attach to the Sysplex Timers. Previously, the ETR feature was optional.

    The z800 ETR connections have an optical transceiver that supports the ESCON Duplex connector and 62.5/125-multimode fiber.

  • Concurrent Hardware Maintenance

    Concurrent maintenance helps enable the replacement of failed units concurrently with system operation. This enhances the processor availability by reducing the need for a system outage to effect the repair. Concurrent maintenance capability exists for the following elements:

    • Power/Thermal
    • ESCON channels
    • FICON Express
    • Coupling links
    • Integrated cluster bus (STI) cable
    • OSA-Express
    • Hardware Management Console
    • Support Element
    • Concurrent Licensed Internal Code
    • External Time Reference (ETR) — depending on ETR link operation
    • Patch Enhancements

    Concurrent Code Patch allows the activation of a patch concurrent with system operation, thereby increasing the availability of the processor by reducing scheduled outage for LIC maintenance. This capability exists for code for the following elements:

    • CP
    • SAP
    • LPAR
    • Coupling Facility Control Code
    • Power/Thermal
    • ESCON channels
    • FICON Express
    • Coupling links
    • Integrated cluster bus channels
    • Internal coupling channels
    • OSA-Express
    • Hardware Management Console
    • Support Element

Note: Not all patches are nondisruptive. Some patches still require a Power On Reset to be activated.

The optional features that provide a high level of availability include:

  • Redundant Coupling Links

    Redundant Coupling Links can be configured between a processor and the CF. This potentially removes a single point of failure for the processor's data sharing capability in the Parallel Sysplex environment.

  • Capacity Upgrade on Demand (CUoD)

    CUoD is intended to provide the capability to add CPs, ICFs, and IFLs nondisruptively in most cases, eliminating the need for a scheduled outage.

  • Capacity Back Up (CBU)

    CBU can enable automatic management of a reserved processor unit (PU) provided by the CBU feature in the event of a processor failure.

Serviceability

The standard features that are intended to provide a high level of serviceability include:

  • Automatic error detection and fault isolation concurrent with system operation
  • Automatic remote support capability
  • High degree of concurrent maintenance capability in hardware and code
  • Multiple Channel Swap — an enhancement for channel problem determination allowing up to four channels to be swapped
  • Status Panel showing status of N+1 power system
  • Enhanced diagnostics for coupling links

Fiber Quick Connect Delivers!

Fiber Quick Connect (FQC) is an option in the e-configuration tool.

The FQC features are for factory installation of IBM Fiber Transport Services (FTS) fiber harnesses for connection to ESCON channels in the I/O cage of the z800. FTS fiber harnesses enable connection to FTS direct-attach fiber trunk cables from IBM Global Services.

FQC, coupled with IBM FTS from IBM Global Services, delivers a solution to reduce the amount of time required for on-site installation and setup of cabling, to minimize disruptions, and to isolate the activity from the active system as much as possible. FQC facilitates adds, moves, and changes of ESCON multimode fiber optic cables in the data center and can reduce fiber connection time by up to 80%.

IBM Global Services provides the direct-attach trunk cables, patch panels, and Central Patching Location (CPL) hardware, as well as the planning and installation required to complete the total structured connectivity solution. Four trunks, each with 72 fiber pairs, can displace up to 240 fiber optic cables, the maximum quantity of ESCON channels in an I/O cage on the z800. This significantly reduces ESCON cable bulk.

The CPL panels use the small form factor fiber optic connector, called Single Connector-Dual Contact (SC-DC). Use of the SC-DC connectors in the CPL panel instead of the ESCON Duplex connectors has reduced the required floor space by 50%.

CPL planning and layout are done prior to arrival of the server on-site using the default CHannel Path IDentifier (CHPID) placement report, and documentation is provided showing the CHPID layout and how the direct-attach harnesses are plugged.

Note: FQC supports all of the ESCON channels in the I/O cage. FQC cannot be ordered for selected channels.
