IBM announces new features and functions for the 9672 Parallel Enterprise Server G5 and G6 models, assisting your enterprise with new: capacity planning options, PCI Cryptographic Coprocessor features, and Queued Direct Input/Output support for OSA-Express Fast Ethernet and 155 ATM Ethernet LAN emulation to reduce CPU cycle consumption and improve ease of use. Thirty-six FICON channels are now orderable on G6 models. For Parallel Sysplex® users, we offer new G5/G6 function and new software support in conjunction with OS/390® Version 2 Release 9.
S/390® Proof Points: Why You Want the G5/G6 Server
Mission-Critical Availability: S/390 availability is the envy of the server industry as the standard for "mainframe"-like qualities, providing a "highly available, manageable, shared resource." Today IBM announces enhanced Capacity Upgrade on Demand (CUoD) functions on G5 and G6 servers to further assist capacity planning for successful e-business workloads.
Data Protection: New G5/G6 PCI Cryptographic Coprocessor support, with new technology, continues IBM's recognized legacy as the vendor with the most secure server technology. IBM's Capacity BackUp capability, together with the Geographically Dispersed Parallel Sysplex, further enhances recovery from disaster events.
Interoperability: DB2® and S/390 connect to everything, enabling e-business! S/390 users benefit from two- and three-tier solutions to leverage the strengths of the IBM server family, S/390's ability to support diverse workloads (unpredictable volumes and application mixes), and S/390's ability to operate at high levels of utilization with mixed workloads and yet continue to provide consistent response times. These strengths extend the life of existing traditional applications into the rapidly expanding world of e-business, Web-enabling existing applications without rewriting.
Query Responsiveness: The one-two punch of powerful S/390 G5/G6 servers along with IBM's Enterprise Storage Server (ESS) offers fast disk access and contention-reducing features such as Parallel Access Volumes and Multiple Allegiance, and delivers data at blistering speeds. The IBM Enterprise Storage Server is the ultimate Storage Area Network (SAN) appliance, providing the information fuel that runs your e-business engine.
Tools to Leverage Your Investment: S/390 shops already have what they need: high ROI, rapid start-up, integration with the operational environment. We put people in the center of the business, by providing ease-of-use within the platform to make life easier for the end user, managing applications to achieve business goals through workload management, and offering support for leading-edge application areas like Customer Relationship Management (CRM). IBM's Parallel Sysplex workload balancing with Cisco's multi-node load balancing, routers, and switches provides an end-to-end solution for your environment.
Incremental Growth: Start small, and add capacity as you need it. S/390 scales "linearly" and provides scalability (within the platform range and Parallel Sysplex clusters) with increased availability and responsiveness.

Capacity Upgrade on Demand Capacity Planning for e-business
Your new e-business application on the Web...it's dynamite, and it's getting the traffic that you hoped for. Your system has a reserve of power offline to handle all the hits. Or picture this. You've told your business analysts that they now have access to all the company's business intelligence data. They're ecstatic. Response time could slow to a crawl in the present configuration. You knew you might need processing power to meet demands of your success and you didn't want to disrupt current operations when you wanted more horsepower. How did you do this? The answer is simple. You used IBM's Capacity Upgrade on Demand (CUoD). It enabled you to start small, then increase processing capacity without disrupting any of your current operations. You've faced your worst fear unsatisfied processing demand and solved it with CUoD.
IBM's Capacity Upgrade on Demand One Year's Experience: A series of recent announcements by other server vendors concerning their versions of processor capacity-on-demand have prompted comparisons to IBM's Capacity Upgrade on Demand, announced early last year (January 1999). Your IBM representative can more fully describe how IBM's basic CUoD is unparalleled in offering flexibility and latent capacity implementation, especially with the following benefits:
All of IBM's G5/G6 servers (installed and new shipments) support CUoD. There is no premium at initial purchase of the G5 or G6 server, or at subsequent activation via CUoD. Customers obtain the price at the time of the upgrade rather than being locked into a predetermined price at initial acquisition.
S/390's Logical Partition manager, PR/SM, permits reassignment of dedicated CPs between logical partitions by varying off a CP in one partition and reassigning it to another. In this case, the same physical CP resource is reassigned and there is no cost penalty for the flexibility. The IBM G5/G6 offline CPs also provide a hot and dynamic spare substitution benefit in case of an active CP failure.
IBM's CUoD does not require the bureaucracy of tracking RTU licenses or a special maintenance contract for inactive CPUs. IBM has provided a special instruction that enables ISVs to monitor capacity increase and maintain the automated management of software licenses. CUoD upgrades use the standard upgrade order process. Required code for the upgrade can be delivered in as little as one day. IBM Service can install the code for concurrent and immediate activation (presence of a trained IBM Service Representative during the upgrade can further mitigate outage risks). We now have available exciting new customer options in the United States and Canada:
These RPQs are administered as attachments to the "IBM Customer Agreement" and enable reduced implementation time of an enterprise's activation request, from the former cycle of one to five days, to minutes. Contact your IBM representative for details, and for availability outside of North America.
Additional CUoD Enhancements
Reserved CP Support in LPAR Mode: S/390's PR/SM has been enhanced to further take advantage of CUoD. A Logical Partition (LPAR) may now be defined with the number of logical CPs greater than the number of physical CPs. Reserved CPs can be specified for the logical partition definition beyond the number of physical CPs currently installed on the model. Therefore, an enterprise planning to do a nondisruptive upgrade (with an LPAR defined of logical CPs equal to the number of physical CPs) does not need to deactivate, redefine, then reactivate in order to take advantage of the new CPs that have been installed. The enterprise simply needs to have defined reserved CPs for the LPAR in advance. This enhancement ensures that any planned logical partition can be as large as the possible physical machine configuration, nondisruptively.
R06 Now CUoD-Capable: New Licensed Internal Code (LIC) allows engines to be added dynamically to the R06 and to the LPARs that are running the CFC Code. Prior to the latest Licensed Internal Code, CUoD for R06 models was not supported. One point to remember: more horsepower will also need more link bandwidth. Coupling Facility receiver channels cannot be dynamically added to the system. Therefore, they must be pre-installed (all the receiver links the installation would require in support of more engines).
CUoD Planning Guide: One year's experience with leading-edge customers has helped our account teams to identify the primary planning issues when planning ahead for nondisruptive capacity upgrades. IBM's Account Planning Guide provides S/390 installations with a roadmap to implement Capacity Upgrade on Demand (CUoD). The guide describes model capacity decisions within IBM's G5 and G6 server "tower" philosophy, necessary Licensed Internal Code requirements, PR/SM configuration tips, and many other planning considerations derived from customer "hands-on" planning of CUoD. Be sure to use the Guide's "Summary Final Checklist" as a cross check to your plan. The latest revision of the popular Account Planning Guide for S/390: Capacity Upgrade on Demand may be found at:
New Cryptographic Security Options
Introducing the IBM PCI Cryptographic Coprocessor (PCICC): Events in IBM's support of cryptographic requirements include:
New for 2000, the IBM PCI Cryptographic Coprocessor (PCICC) is an orderable feature that adds additional cryptographic function and cryptographic performance to G5/G6 servers. A fully configured PCICC implementation on the G5 or G6 server can process up to one thousand 1024-bit RSA Private Key Decryptions per second. Each PCICC feature is built around an IBM 4758-2 PCI Cryptographic Coprocessor card embedded in an adapter package for installing within a G5 or G6 server. Support for PCICC will be provided by OS/390 V2R9 with new ICSF functions. The IBM PCI Cryptographic Coprocessor feature coexists with and augments the IBM CMOS Cryptographic Coprocessor, standard on G5 and G6 servers. ICSF will transparently route application requests for cryptographic services. Either a CMOS Cryptographic Coprocessor or a PCICC will be invoked (depending on performance or cryptographic function) to perform the cryptographic operation. For example, the IBM CMOS Cryptographic Coprocessor performs synchronous functions (such as those used in the Triple DES standard) but does not execute certain asynchronous functions such as RSA Key Generation which will be performed on the PCICC. Up to eight PCICC features can be ordered to provide increasing cryptographic processing capacity as customers expand their usage of e-business applications requiring cryptographic processing.
New Functions: PCICC provides several additional functions to enhance the security of public/private key encryption processing:
Capacity BackUp: Enhancements for 2000
The G5/G6 Capacity BackUp capability enables enterprises to provide flexible, cost-effective Disaster Recovery on their S/390 servers. Additional refinements in the CBU verification process, via IBM's Remote Service Facility (RSF), have significantly shortened the CBU Activation time. Where applicable, the CBU authorization turnaround should take approximately five minutes. This process is called CBU Automatic Password Authentication. Upon operator request, the G5/G6 server will call home via RSF, verify authorization, and automatically unlock the increased server capacity. CBU Smart Reactivation reduces potential outage duration, during a disaster event, if an MCM needs to be changed (while CBU is activated). Expedited Install/Bringup Time for CBU Implementation enables installations to copy Activation and SAD profiles at any time and restore them at any time. CBU Licensed Internal Code is now associated to a specific server serial number (to protect the installation from erroneous CBU activation on the wrong server).
New CBU Customer Reference Document: The publication Emergency Backup/Capacity Backup User's Guide (GC38-0612) is an aid for personnel involved in the planning of Emergency Backup (EBU)/Capacity Backup (CBU) function. The document is comprised of two sections: Main and Appendix. The Main section is oriented to IBM's support personnel. The Appendix is provided to IBM customers for EBU/CBU ordering and planning activities. Copies may be ordered through your IBM representative.
Greater than 3X Increase in Subchannel Addresses for G5/G6 Servers
Another proof point of IBM's balanced system design: Larger disks such as the industry-leading IBM ESS disk subsystem and new disk functions coupled with bigger and faster processors will rapidly utilize all 80 K HSA subchannel addresses that are currently allowed in S/390 systems. To address this potential limit to efficient utilization of the IBM S/390 CMOS servers' power and end-to-end bandwidth capabilities, the current subchannel capability is being increased to 288 K subchannels. This increase will be good news to those customers that are actively engaged in fully exploiting ESS disk subsystems, remote copy technology, "snap" technology (snap copy on RVA and flash copy on ESS), the Parallel Access Volume feature on the ESS disk subsystem, or server consolidation through the use of LPARs. The 288 K HSA subchannel support will provide immediate relief to those customers who are increasing the number of applications within a single system and were previously constrained by the number of subchannels. This increase will also benefit the sharing of channels across LPARs using MIF, which comes into play in Sysplex, GDPS, and ESS almost 4X the previous limit. (The 36K subchannel/LPAR limit remains.) Customers need to consider that when device addressing capabilities are significantly expanded, there may be additional HSA storage required to accommodate the increase in the associated configuration tables. In some instances where the current HSA requirement is near a storage boundary, additional memory may need to be allocated.
FICON Channel Capacity Increased to 36 on G6 Enterprise Servers
Channel requirements for Enterprise Server class systems are driven by several considerations. While an enterprise has historically focused on "channel count," the primary issue is adequate connectivity to provide acceptable performance and availability. Moreover, today's e-business environment (in which workloads may radically deviate from a legacy design concept) may actually exceed the original design point of older channel architectures. Connectivity options then, are:
Increasing the total channel count requires more infrastructure, both within the system and within the data center; this includes power, footprint, cables, patch panels, switch ports, systems management, and configuration management. Moreover, exploitation of new technology, such as link speeds or I/O device capacities, cannot be fully leveraged by new workloads in an old design point environment.
The other two options, more throughput capability and better utilization of existing channels, are the foundation of the FICON strategy. The FICON connectivity solution is based on industry-standard Fibre Channel technology and leverages our exclusive native FICON architecture. FICON has been submitted to the National Committee for Information Technology Standards (NCITS) for consideration and potential adoption as a new industry standard for large-scale data transfer. FICON was specifically created to meet the I/O bandwidth and connectivity demands of today's e-business workloads while also providing significant benefit to more traditional business applications. A quick technology fix may be expedient, but Enterprise Server class customers demand a total solution. IBM is aware of this requirement and has created a complete migration offering with the FICON Bridge feature on the 9032-005 ESCON® Director to allow customers to begin the migration to this new environment, and has introduced leading-edge storage function and performance capabilities with the Enterprise Storage System with more to come! World-class Enterprise Server technology (G5/G6) and storage (ESS) demand a robust I/O connectivity solution that supports fast devices and link speeds, greater addressability, extended distance topology, and increased control unit intelligence. The response to that demand for a more capable channel is FICON.
More capable channels require less physical channels and ease demands on the infrastructure. This can translate into real cost savings, which can be re-allocated from infrastructure overhead to productive, leading-edge application development. In the final analysis, what type of I/O channel technology do you want supporting your mission-critical enterprise business applications now and into the future many "skinny" channels with limited architectural capabilities, or fewer high-capacity channels with robust architecture? Your IBM representative can assist you with your decision.
G5/G6 SAP Measurements Update: The Best Performer Industry-Wide
In a laboratory capacity benchmarking environment where there is no contention for channels, ESCON Directors, control units, or devices, a G5 SAP has the capacity to process 37,000 start subchannels/second (ssch/sec); a G6 SAP in Xn7 models has the capacity to process 50,000 ssch/sec; and a G6 Turbo SAP in Zn7 models has the capacity to process 56,000 ssch/sec. As most G5 models have two SAPs standard and all G6 models have two SAPs standard, they will have two times the capacity, or up to 74,000 ssch/sec for G5s and up to 112,000 ssch/sec for G6.
TPF environments where requests may get queued at the channel instead of the SAP have a SAP capacity for G5 of 20,000 to 24,000 ssch/sec and G6 of 25,000 to 34,000 ssch/sec. As most G5 models have two SAPs standard and all G6 models have two SAPs standard, they will have two times the capacity, or up to 40,000 to 48,000 ssch/sec for G5 and 50,000 to 68,000 ssch/sec for G6 models. Non-TPF environments where ESCON busy path conditions are redriven by the SAP (assume one redrive for each ssch) have a capacity of 12,000 to 15,000 ssch/sec for G5 and 16,000 to 20,000 ssch/sec for G6. As most G5 models have two SAPs standard and all G6 models have two SAPs standard, they will have two times the capacity, or up to 24,000 to 30,000 ssch/sec for G5 and 32,000 to 40,000 ssch/sec for G6 models.
Higher I/O rates are possible with better tuned configurations and if additional SAPs are added. Conversely, lower rates are also possible with poorly tuned environments. Additional SAPs can be added if spare PUs are available and if the number of SAPs does not exceed the number of CPs. On all G6 models the addition of SAPs is a code-only change (no additional hardware required).
S/390 Network Connectivity Update for 2000
e-business Applications May Become Bandwidth-Hungry: To ensure that the G5 and G6 servers can deliver the bandwidth required without requiring an increase in I/O resources, IBM introduced the third generation of the S/390 Open Systems Adapter, OSA-Express. OSA-Express Gigabit Ethernet (GbE) became available in June 1999, and OSA-Express Fast Ethernet, 155 ATM single mode, and 155 ATM multimode became available January 31, 2000.
The OSA-Express Fast Ethernet and 155 ATM features replace the currently available S/390 Open Systems Adapter 2 Fast Ethernet and 155 ATM features on the S/390 Parallel Enterprise Servers Generation 5 and Generation 6.
The new OSA-Express features help to ensure that the increasing high volumes of data traversing the Local Area Network (LAN) do not encounter a bandwidth bottleneck, whether data is exchanged via intranet Web servers, centralized file servers, the Internet, or extranets. The new OSA-Express Fast Ethernet and 155 ATM features are capable of achieving line speed (100 Mbps and 155 Mbps respectively), while functionally equivalent to OSA-2.
Note: Actual throughput is dependent upon many factors, including traffic direction, the pattern of acknowledgment traffic, packet size, the application, TCP/IP, the network, disk subsystems, and number of clients being served. IBM cannot confirm the accuracy of performance, compatibility, or any other claims related to non-IBM products. Questions regarding the performance, compatibility, and attachment capabilities of non-IBM products to the OSA features should be addressed to the suppliers of those products.
The OSA-Express Fast Ethernet and 155 ATM features:
IBM Resource Measurement Facility RMF (5655-084) , an OS/390 optional priced feature, has been enhanced in support of the OSA-Express Fast Ethernet and 155 ATM features. This allows the installation to better understand what is occurring within a feature for:
With this enhanced support, a user can now better understand the possible bandwidth bottlenecks, and can perform root cause analysis. Additional details may be found in the document OS/390 Resource Measurement Facility Report Analysis (SC28-1950-04).
Tivoli® Storage Manager and OSA-Express , the replacement for ADSTAR® Distributed Storage Manager (ADSM), is an advanced storage management solution. It integrates unattended network backup and archive capabilities with storage management and powerful disaster recovery functions. As a client/server storage management product, Tivoli Storage Manager provides administrator-controlled, highly automated, centrally scheduled, network-based backup and archive functions for workstations or LAN file servers.
With recent enhancements to Tivoli Storage Manager on S/390, the advent of the OSA-Express GbE features, and the new Queued Direct I/O (QDIO) architecture available on IBM G5/G6 servers and OS/390 Version 2 Release 7 with PTFs, significant improvements have been observed.
Simulated backup measurements, in a controlled environment, have yielded a throughput of 25 MB/sec per OSA-Express GbE feature, and a throughput of 150 MB/sec using six OSA-Express GbE features. In a separate set of tests, using an RS/6000® S70 as a Tivoli Storage Manager client running 10 Tivoli Storage Manager client sessions to a G5 server backing up to an S/390 Enterprise Storage System over a single OSA-Express GbE feature, a throughput of 68 MB/sec was measured. These rates demonstrate the potential of Tivoli Storage Manager and the underlying software and hardware. These are lab tests in a controlled environment and actual customer results may vary depending on applications, data sizes, storage and network devices, and other factors. A white paper is available from your IBM representative.
Enhancements to Tivoli Storage Manager include the exploitation of OpenEdition® sockets enabling the performance improvements in TCP/IP, a multi-threaded design, asynchronous I/O, and self-tuning algorithms. S/390 G5/G6 servers are excellent performing Tivoli Storage Manager servers.
OSA-Express GbE, New Function for ESS Data Sharing: OSA-Express GbE is now moving to the forefront of the IBM Enterprise Storage Server's data sharing strategy, as a replacement of the IBM InfoSpeed Data Gateway. OSA-Express GbE provides high-speed inter-systems connectivity and data sharing between host and client resources. Since OSA-Express GbE is an industry-standard open interface, the current infrastructure of hubs, switches, and routers can be used. No additional TCP/IP skills are required, since standard TCP/IP and File Transfer Program (FTP) are used. The result: a nondisruptive transition to an industry-standard interface that can deliver significant performance improvements over currently available TCP/IP solutions.
New: QDIO Support for OSA-Express Fast Ethernet and 155 ATM Ethernet LAN Emulation: (Planned Availability: Third Quarter 2000.) Queued Direct Input/Output (QDIO) was implemented and supported by Communications Server for OS/390 Version 2 Release 7 with PTFs (CS OS/390) and OSA-Express GbE. QDIO is now being offered for the OSA-Express Fast Ethernet feature and the OSA-Express 155 ATM features (multimode and single-mode fiber) when configured for Ethernet LAN Emulation.
QDIO is a new, highly efficient data transfer architecture introduced to satisfy the increasing volume of TCP/IP applications and the increasing demands for bandwidth. QDIO returns CPU cycles for applications' use, avoids host interrupts by sharing a common storage area with CS OS/390, and minimizes the movement of data. This improves ease-of-use by dynamically defining the address table of the OSA-Express feature, eliminating data entry errors and incompatible tables, and making possible LPAR-to-LPAR communication.
QDIO has three key components:
The TCP/IP profile information is entered once, avoiding duplicate data entry. A dynamic OAT is key for TCP/IP Virtual Internet Protocol Address (VIPA) Takeover, which became available in OS/390 Version 2 Release 8. With VIPA Takeover, when a TCP/IP stack fails, the IP addresses registered to the OSA-Express feature are dynamically changed; thus one TCP/IP stack can take over the work of the failed TCP/IP stack; the IP client is unaware of the activity.
With the introduction of QDIO support for OSA-Express Fast Ethernet and OSA-Express 155 ATM, when configured for Ethernet LAN Emulation, the features now support two Channel Path Identifiers (CHPIDs) types which are mutually exclusive. If the feature is defined in the Hardware Configuration Definition (HCD) as a CHPID type of "OSE," SNA and IP traffic can flow through the port. This requires the OSA Address Table to be built manually using the S/390 Open Systems Adapter Support Facility (OSA/SF). If the feature is defined in the HCD as a CHPID type of "OSD," only IP traffic will flow through the port, and the OAT is built dynamically.
Note: OSA/SF is still needed for the definition of the emulated/logical ports on the OSA-Express 155 ATM feature.
QDIO is an exclusive IBM CMOS S/390 server function that allows the OSA-Express microprocessor to communicate directly with S/390 memory using data queues. Communication remains active and data exchanges are direct and continuous, minimizing I/O interrupts.
QDIO support for OSA-Express Fast Ethernet and 155 ATM Ethernet LAN Emulation is available via a Licensed Internal Code update, and is enabled in CS OS/390 Version 2 Release 8 via a Program Temporary Fix (PTF). Contact your IBM representative for further information.
LPAR-to-LPAR Communication News: Like the OSA-Express GbE features, the OSA-Express Fast Ethernet feature has the ability to send and receive IP traffic between Logical Partitions (LPARs) without sending the IP packets out to the LAN and then back in to the destination LPAR. LPAR-to-LPAR communication makes possible routing of IP packets within the same host system. The OSA-Express Fast Ethernet feature will examine the destination IP address; if the destination is on the same host system, the IP packets will be routed to that IP address without sending the IP packets out to the LAN and then back in again (ignoring the fact that the source and destination hardware address are the same). Any application that requires traffic to flow LPAR-to-LPAR on the same system can benefit from this support. This support became available on the availability date of the OSA-Express Fast Ethernet feature, January 31, 2000.
The S/390 Asynchronous Data Mover Facility, ADMF, was invented to improve storage-to-storage movement of large blocks of data in bipolar machines. It is exploited by DB2 Hiperpools. The continued evolution of CMOS processor and memory technology in G5/G6 has improved synchronous data movement using the Move Page instruction to the point where its performance is on a par with ADMF.
The Fast Sync Data Mover Facility will be implemented on G5/G6 and future processors as an indicator to DB2 that Move Page should be used in place of ADMF. DB2 will be issuing a PTF to check for this indicator and use Move Page instead of ADMF. DB2 will continue to use ADMF on pre-G5 machines. DB2 without the PTF will also continue to use ADMF on G5/G6. IBM however plans to remove ADMF from future servers.
IBM Classes for Unicode for OS/390
On June 18, 1999, IBM made it easier for developers to create multilingual applications by offering free and public access to the source code for software that enables applications to work in different languages and countries. The IBM Classes for Unicode, based on the Unicode industry standard, is the first software package available under a new IBM Public Source License. The license, a direct result of collaboration with the open-source community, allows source code to be downloaded freely off the Web. Developers can use the software, change it, and share their improvements with others.
Using the Unicode classes, developers using a range of operating systems can write applications that support a wide variety of global languages. Applications can be easily localized by changing simple data files to automatically adapt dates, currencies, numbering schemes, and characters to fit an individual country's language format. The Unicode classes will automatically format currencies into yen for Japanese usage, for example, or change date fields to correspond to German formats.
The IBM Classes for Unicode are currently available for the AIX®, Linux, Solaris, and Windows NT operating systems. OS/390 will soon be added to that list. IBM Classes for Unicode for OS/390, including source code, will be available for download from the Web site:
VS FORTRAN Update
VS FORTRAN Now Optimizes Extended Precision Calculations for Improved Execution Performance on G5 and G6 S/390 Parallel Enterprise Servers: (Available Second Quarter 2000.) APAR PQ29366 extends the usage of the Additional Floating Point Registers to calculations that use Extended Precision Floating Point numbers. This new capability also for the first time includes the ability for the VS FORTRAN compiler to optimize computations involving Extended Precision Floating Point operands. This enhancement will provide performance improvement for programs using Extended Precision Floating Point operands. The amount of such improvement will vary and is dependent on the application program, particularly the intensity of such computations in any specific program.
Customers who have FORTRAN programs that use Extended Precision Floating Point computations may wish to consider the benefits of using the Additional Floating Point Registers feature offered by the G5 and G6 servers in conjunction with this enhancement to VS FORTRAN to improve the execution efficiency of these programs.
Customers who have been prevented from using the improved accuracy obtained when using Extended Precision Floating Point calculations because of the lack of optimization available in prior levels of VS FORTRAN may wish to consider potential accuracy improvements in their FORTRAN programs by changing to use this capability now that VS FORTRAN will provide its world-class optimization support for Extended Precision Floating Point calculations for use on the G5 and G6 servers. Recompilation is required to take advantage of these new capabilities.
Parallel Sysplex Update
IBM continues its leadership in technology, software, and services to provide highly scalable capacity, workload balancing, resource sharing, and maximum availability via its Parallel Sysplex technology. IBM's Internal Coupling channels (ICs) and Integrated Cluster Bus (ICB) are exclusives within IBM's G5 and G6 servers, and provide up to 4% better coupling efficiency over HiPerLinks while at the same time reducing the hardware requirements and simplifying the configuration. G5 and G6 ICB technology can provide up to 50% savings for coupling facility operations, when compared to HiPerLinks. The value of these IBM exclusives has not been overlooked by enterprises. Whether the need is to run a Parallel Sysplex cluster in support of e-business, an ERP application, or a data warehouse or online workloads running tens of millions of transactions per day, IBM Parallel Sysplex clustering provides superior technology to handle capacity growth, availability, and system management in the market today. Customer acceptance continues to grow with over 300 new resource sharing and over 100 new data sharing implementations in 1999.
Automatic Enablement of Capacity BackUp (CBU) for the Geographically Dispersed Parallel Sysplex (GDPS): GDPS-CBU enables automatic management of the reserved Central Processors (CPs), provided by the CBU feature. In the event of a server failure and/or a site failure, GDPS automation will:
In the event of a server or site failure, GDPS requires available standby server resources that can be immediately displaced and acquired to restart the mission-critical workloads. Standby server resources are typically used to execute discretionary workloads, such as systems test, or applications development. However, production workload system requirements usually exceed the discretionary workload system requirements; an enterprise without CBU may therefore incur cost of spare processor resources, with associated software license charges. IBM software license temporary license transfer feature allows the software licenses to be temporarily transferred from the production systems to the newly expanded systems. Given the flexibility of the GDPS-CBU implementation, the enterprise has full restart capability, or restart of a critical subset within the production workload whichever best responds to the situation.
Upon detection of a server, or site failure or planned disaster event, GDPS will "call-home" to IBM via IBM's Remote Support Facility (RSF). The call-home will automatically confirm CBU participation, and unlock the target configuration; the reserved CPs are then varied online.
Once the necessary resources have been acquired, the enterprises' critical applications are automatically restarted. This automated recovery process is especially critical in today's competitive e-business world.
IBM's Fiber Saver is another key technology to the GDPS solution. The IBM Fiber Saver (Machine Type 2029) is a Dense Wavelength Division Multiplexor (DWDM) which transports multiple protocols over a single fiber optic cable up to 50 km. Multiple protocols may be multiplexed over a full-duplex cable at up to 1.2 GB/second per channel. Since IBM's Fiber Saver substantially reduces the quantity of cross-site fiber optic cables, fiber lease costs and additional fiber optic runs can be greatly reduced. Moreover, Fiber Saver may obviate additional cable runs to install GDPS. Refer to Hardware Announcement 199-305 , dated November 23, 1999.
S/390 Parallel Sysplex Messaging CFCC Support: IBM's Coupling Facility Control Code has been enhanced to support extensions to the list structure. These enhancements in CFCC Level 9 will support messaging architecture. Message passing is critical for applications that run across multiple systems in a Parallel Sysplex cluster. With the appropriate exploitation, the new list structure enhancements will enable messaging across the Parallel Sysplex cluster transparent to applications (providing improved capacity, availability, and dynamic workload balancing for application servers).
MQSeries® will be looking to exploit these new functions in future releases of the MQSeries for OS/390 product. Refer to the XES Parallel Sysplex Enhancements section of this announcement XES CF List Structure Architecture Extensions.
Model R06 Enhancements More Connectivity: IBM's Order Process system now automatically installs a larger (four bus) Multichip Module (MCM), on 1-ICF through 4-ICF models, if the configuration requires additional connectivity; these models now offer up to 24 ICBs.
Software Enhancements for Parallel Sysplex Cluster
Enhanced Contention Analysis (ECA) is available now and is designed to significantly improve multi-system availability and serviceability for both base and Parallel Sysplex cluster environments with commands to provide diagnostic information in the event of a multi-system "hang" condition. ECA is available only with GRS in a Sysplex. Without ECA, if an operator is faced with a multi-system "hang" condition, there is little or no problem determination information, and therefore problem elimination can be questionable.
Today, clusters can only detect hard failures, that is, when a system is already down. Many system failures do not manifest themselves as a hard failure; the system does not actually fail but it ceases processing useful work. These type of failures are the most difficult to detect and can at times cause multi-system outages. Only in a Sysplex with Enhanced Contention Analysis can clusters detect this type of failure and allow actions to be taken before a hard failure or multi-system outage occurs. With ECA, commands can be entered to retrieve and analyze information kept by GRS, to pinpoint the problem task, address space, or system and remove it from the configuration (for example, cancel a job, recycle a subsystem, or partition an image), to avoid a potential multi-system outage condition. ECA is valuable in detecting multi-system "hang" conditions involving components such as Automatic Tape Sharing, JES2, consoles, and RACF®.
The new commands will allow different displays of data:
These command responses can help identify a problem and allow appropriate action to be taken, enabling the Sysplex to continue processing and meet its high availability design objective.
ECA is available now via the PTFs for OW38979, on OS/390 R3 and higher. For more detailed information, visit IBM's Parallel Sysplex Web site:
Shared Hierarchical File Systems (HFS): In OS/390 Version 2 Release 9, Shared HFS support for the Parallel Sysplex environment adds support to the UNIX® System Services file system for simultaneous Read/Write (R/W) access of the same HFS running on different OS/390 images in the Parallel Sysplex cluster. Currently, read/only concurrent access is allowed. This Shared HFS support benefits Web-server applications, Lotus®, the Manufacturing suite, the Content Management Strategy (digital data, multimedia) and others who access the hierarchical file system (HFS). This new support can make data and information residing on the HFS available to your enterprise at any time, no matter where the applications are running in the Parallel Sysplex cluster.

Ease of Use: IBM/390 Parallel Sysplex technology continues to provide enhancements to simplify systems management, reduce costs, and improve overall system performance with such items as:
Two Web-based tools (wizards) have also been recently made available:
Internet-based wizards are innovative approaches used to simplify some of the planning and configuration tasks necessary for OS/390. The Parallel Sysplex Configuration Assistant exploits recommended parameters to guide a systems programmer through the process to define dataset naming conventions and control datasets, for example, to assist creating Parallel Sysplex CFRM, ARM, SFM, and other policies. Moreover, Coupling Facility structure sizes for all resource sharing exploiters may be calculated, based upon built-in recommendations. Finally, the Parallel Sysplex Configuration Assistant will build JCL for parmlib members, and more. The Parallel Sysplex Configuration Assistant allows sessions to be saved, enabling multiple configuration definitions. Sessions can be easily copied into the respective parmlib members and policies that exist on the OS/390 system. The S/390 Parallel Sysplex Configuration Assistant is available at:
S/390 Coupling Facility Structure Sizer can be used to help you estimate your IBM CF structure storage requirements. Without the CF Structure Sizer, S/390 Parallel Sysplex users would need to manually size their Coupling Facility storage consumption. The algorithm to determine storage for each exploiter of the Coupling Facility may vary significantly, from exploiter to exploiter. Although the algorithms and process are well documented, the potential for human error leading to poor system performance (in some cases, outages) does exist. The IBM S/390 Coupling Facility (CF) Structure Sizer provides "one-stop shopping" for any of IBM CF structures' sizing. The S/390 Coupling Facility Structure Sizer uses selected inputs and respective calculations to generate the initial and maximum structure size values for the CFRM policy. The sample CFRM statements that are generated by the tool can then be easily copied into the CFRM policy on the OS/390 system. This Web-based tool supports all IBM structures, (CICS®, DB2, IMS, and S/390 Resource Sharing structures); it can be found at the Parallel Sysplex Web site at:
System Automation for OS/390 Release 1.3 SPE Available Now: Parallel Sysplex automation needs to deal with the resources that are critical to the Parallel Sysplex cluster and application availability. This SPE can help operators to manage critical Sysplex resources like Coupling Facilities and CF structures, coupling data sets, Sysplex messages, and more. Operators will benefit from reduced Sysplex operations complexity. Also, automation routines exist to automate various XCF messages. Routines are available to take Coupling Facilities in and out of the Parallel Sysplex cluster and rebuild structures. In addition, some Parallel Sysplex resources are highlighted if they appear to be in an exception state (to help identify a problem before it becomes severe). This SPE is available via APAR OW39485/PTF UW99278. More information can be found on the System Automation Web site:
Today, System Automation for OS/390 already helps you automate a Sysplex by offering a broad range of functions. Marion Diederichs from Victoria Insurance says, "Without System Automation for OS/390, we would be not able to manage our Parallel Sysplexes."
System Automation for OS/390 also is the automation platform for GDPS; refer to the GDPS-CBU section in this announcement.
System-Managed Rebuild Available with OS/390 Version 2 Release 8 and Higher: Prior to OS/390 R8, only "user-managed" structure rebuilds have been available. The challenge for the "user," that is, the active connector set, was that it needed to be involved directly in rebuilding of the structure (participate in event exit protocols, explicitly allow or disallow XES rebuild process depending on code to support the necessary protocols). When the rebuild is system-managed instead of user-managed, the system performs all of the significant steps in the overall rebuild process on behalf of the connectors, with minimal participation by the connectors. System-Managed Rebuild provides to system operations:
Early exploiters of System-Managed Rebuild include the JES2 Checkpoint and WLM multisystem enclaves, as described later. Other exploiters are planned and will use the new API/protocols, to provide rebuild process, and further minimize Parallel Sysplex operations complexity. Software vendors who do not presently support rebuild for their structures may also exploit this improvement. To benefit from System-Managed Rebuild, at least two Coupling Facilities must be at CF level 8 or higher (the one in which a structure exists prior to rebuild, and the one in which it exists after the rebuild). All systems in the Sysplex must be running at least OS/390 R8 or later releases.
Workload Manager (WLM) Multisystem Enclaves support in OS/390 Release 9 provides the capability to manage and report on parallel work requests that are executed on multiple OS/390 images (for example, span a Parallel Sysplex cluster) as a single entity. This support extends the scope of an WLM enclave to include dispatchable units running on different OS/390 images in a Parallel Sysplex cluster, perform period switch based on a transaction's overall consumption of resources on all systems, and report a single completed transaction per parallel unit-of-work.
For example, work that begins as a part of a job on one system can be split into parallel tasks that can then be exported to other systems for parallel processing. This function will simplify customer exploitation of applications/subsystem function in a Parallel Sysplex cluster such as DB2 Intelligent Miner for Data for OS/390 V6.1 (available September 1999). This WLM enhancement:
Enclaves can be managed across the Sysplex with the new function. Workload Manager is able to change the resource allocations as the units of work change. You can ensure the work receives appropriate resources no matter where it is running. OS/390 V2R7 Resource Measurement Facility (RMF) offers this support through an APAR (OW41317). This support requires CFCC Level 9 with OS/390 Release 9 and introduces a Workload Manager structure.
OS/390 XES Parallel Sysplex Enhancements: The following Parallel Sysplex enhancements are available in OS/390 Version Release 9, or SPE, and will aid IT staff to trouble-shoot, as well as run a more efficient Parallel Sysplex configuration.

Data Warehousing Solutions
Using S/390 G5/G6 Servers and the Enterprise Storage Server: As we move into the twenty-first century, businesses facing the challenges of e-business and competing in a global marketplace are increasingly turning to business intelligence technologies to help them gain a competitive edge. The powerful combination of IBM's S/390 G5/G6 servers with DB2 for OS/390, and the newly announced Enterprise Storage Server (ESS), is unsurpassed for delivering fully integrated business intelligence/data warehousing solutions across all industries. The cornerstones of how these solutions drive business value are:
In Review: IBM's S/390 Solution for e-business
Companies today are no longer asking if they should have an e-business strategy, but rather how to make all of the pieces of their strategy fit together in the most cost-effective and intelligent manner. The IBM S/390 Solution for e-business will solve this challenge with an integrated e-business services solution approach.
The three major areas of e-business are: content hosting and Web integration, collaborative groupware computing, and e-commerce.
In addition to preconfigured solutions, it makes sense in an e-business environment to develop new, dynamic applications that can be accessed by any network client. On S/390, this is accomplished through the use of the Java programming language developed by Sun Microsystems, Inc.
The true value of Java for OS/390 is in the application execution. A commercial application typically involves the access of data, the transaction, and the processing of the resulting data. OS/390 is positioned to perform this end-to-end processing better than alternative platforms.
IBM's first network computer, the IBM Network Station, combines the simplicity and low cost of nonprogrammable terminals with leading-edge application technologies by attaching to any type of IBM server. It is ideal for multi-platform computing environments. You have access to all kinds of applications running on one server or many servers, to the worldwide resources of the Internet (or a private intranet), and to the fast-emerging world of Java applets and applications downloaded on demand from Internet or intranet servers.
The IBM Network Station Series 1000 extends the IBM Network Station family of network computers by delivering robust support for business applications written in Java while effectively meeting all of your other desktop computing demands, from accessing traditional business applications to accessing your corporate intranet and the Internet.
The IBM S/390 Solution for e-business (formerly the e-business Server Offering [ebSO]), has been created to provide an attractively priced services package to migrate S/390 customers to an e-business environment. IBM's implementation services will help customers identify and plan for the right e-business solution, perform product installation, and provide skills transfer to the customer's support staff. It is the intent of the services to enable and integrate the selected e-business application into a production environment within one year. For details, see your IBM representative.
