Overview

IBM is introducing 16 new Generation 5 S/390 (R) Parallel Enterprise Server models. Fifteen general purpose and one Coupling Facility model exploit the latest IBM Complementary Metal Oxide Semiconductor (CMOS) technology yielding up to 2x the performance of the corresponding G4 models. The 9672 R06 is a more powerful Coupling Facility which can be upgraded to other G5 models. 9674 C04 and C05 CF's can upgrade to 9672 R06's. All G5's offer substantial performance and functional and feature options over previous generations of CMOS and bipolar Systems.

New functions and features such as IEEE Floating Point, TDES cryptography with dual path cryptographic coprocessors, FIbre CONnection channels (FICON (TM)), Internal Coupling channels, Integrated Cluster Bus coupling connections and Fast Ethernet connections are available on G5 models. G5's design excellence balances processors, memory and I/O connectivity, optimizing them for Enterprise computing. Memory and I/O bandwidth has increased over 100% from previous CMOS servers. New architecture, tailored to TCP/IP performance improvements, makes G5 servers extremely powerful and scalable commercial Web Servers. In addition to the new optional Fibre Channel, G5 Servers will also support Geoplexes and new Open Systems Adapter-2 technology. Parallel Sysplex (R) cluster technologies also have added flexibility, performance and connectivity.

The new models provide the Parallel Sysplex customer more Single Systems Image (SSI) capacity, continuous availability, scalability and performance, while providing the single system customer with the upgradeability, performance and functionality to increase existing workload capability, and provide increased capacity for the new workloads every enterprise has witnessed. G5 has significant improvements for decimal instructions compared to G4. The S/390 G5 Parallel Enterprise Server models also provide increased performance and throughput for customers who have substantial floating point arithmetic calculations and other types of numerically intensive workloads. Furthermore, the S/390 G5 Parallel Enterprise Server models also offer new instructions to further enable C/C++, and Java (TM).



Intended Customers

The new S/390 G5 Parallel Enterprise Server models' customer segment includes the existing S/390 processor inventory up through the ES/9000 (R) 9021 711-based processors, upgrades from 9672 model R2, R3, G3 and G4 servers, and 9674 Model C04 & C05 coupling facilities as well as equivalent Plug Compatible Machine (PCM) inventory.

Both existing traditional and new workloads will benefit from the G5 server's robust performance, scalability and improved availability.

Performance Information

LSPR Measurements will be available September 1998.

Preliminary performance measurements on a limited model set confirm up to 2X performance improvement, compared to G4 models.



S/390 Parallel Enterprise Generation 5 Server -- Design Excellence

Enhanced Generation 5 CMOS Bi-nodal Processor Sets: G5 processors utilize CMOS 6X technology to pack approximately 4 million circuits on a 14.6mm chip. G5 processor sets have 6 Processor Units supported by a Storage Control chip, 4 Storage Data chips and 2 Memory Bus Adapter chips. The largest models have 2 sets of 6 PUs each which can support up to a 10 Way Multi-Processor and 2 System-Assist Processors (SAPs) -- dedicated I/O processors.

The chip count on the Generation 5 MultiChip Module (MCM) was reduced from Generation 4 from 30 to 29. Securely enclosed within the module are two dual path Crypto Chips and the System Clock (Clk) chip. These 3 chips, along with the 13 (1 processor set) or 26 chips (2 processor sets) are mounted using IBM's Controlled Collapse Chip Connection (C4) technology on advanced ceramic substrates.

The G5 processor set design eliminates bottlenecks and contention of previous CMOS and BiPolar designs. G5 has a new System "nest" structure that uses three system busses an improvement over G4's single system bus that handles address, data and controls for memory fetches. The cache structure of G5 is also improved. G5 has 256 KB of Level 1 cache on each PU. G5's large on chip L1 cache increases the L1 cache hit success ratio for most workloads. Backing G5's larger L1's is a larger and improved Level 2 cache located on the SD chips. The Processor sets have 4 MB of shared Level 2 cache, 1 MB on each of the SD chips in a processor set. L2 cache is shared on 6 PU's in two G5 sets, an improvement over the G4 design of sharing L2 across 3 PU's in 4 sets. The G5 System design having up to 8 Mbytes of L2 cache (2 sets) eliminates the need for Bus Switching Network (BSN) chips that comprised an additional cache level (sometimes called an L 2.5) that was part of CMOS G3-G4 System designs. The G5 memory line size has also been increased to 256 bytes to allow additional prefetching. G5's cache access improvements, contention elimination and cycle time improvements (approximately 20% over G4 models) combine to increase performance over G4 and 711 based models (refer to previous section -- Performance Advantages).

The use of a Branch History Table (BHT) enables G5s to have more throughput than G4s. CMOS integration and the integration of processor elements in the single PU chip, with a larger balanced cache structure enables G5 Systems to have more throughput than 9021 711 based processors. G5 processors have much less variability of throughput for different workloads than G4 processors. The streamlined balanced design of G5 processor sets significantly reduces queing effects that limits BiPolar or CMOS (high end) processor performance.

Generation 5 Processor sets can utilize up to 24 Self Timed Interconnect (STI) busses to gather or send data. The STI bandwidth of 333 MB/sec bidirectional allows data to be moved to and from the System in a fast and efficient manner. G5's can have up to 24 GB of storage, giving customers the ability of having large amounts of central memory (Level 3) to support up to 15 LPARS.

Reduced Cost of Computing

The new S/390 G5 Parallel Enterprise Server models continue to enable significant savings with respect to energy, facilities overhead, and maintenance costs when compared to older technology processors. Customers who migrate from ES/9000 or comparable non-IBM systems can see up to 97% savings in energy costs (including power and cooling), up to 65% in service and maintenance costs, and more than 91% in floor space requirements. Low energy requirements leads to economies in facilities infrastructure. This may avoid machine room expansion, additional power distribution retrofits, and additional heat exchanger burden. The universal electrical primary source capability of IBM's new servers accommodate direct attachment to any electrical utility worldwide.

Increased Server Storage Capability to 24 GB: IBM leads the industry by offering up to 24 GBs of server storage capability on the new S/390 G5 Servers and Coupling Facility R06 model. This enhances the ability to balance S/390 G5 system resources with the performance of the processor sets. In PR/SM (TM) LPAR mode, models with greater than 2 GBs installed storage can configure some or all of the installed storage as central storage. Each individual logical partition is limited to a maximum of 2 GBs of central storage. The sum total of all logical partition central storage can exceed 2 GBs up to the limit of processor storage.



Generation 5 Memory Structure -- Capacity and Additions

Generation 5 models use 1 GB, 2 GB, 3 GB, 4 GB and 6 GB memory cards. Models RA6, R16, RB6, R26, RC6 and RD6 always have 2 cards. Models R36, R46, R56, R66, R76, R86, R96, RX6 and YX6 have 4 cards. Model R06 has either 2 or 4 cards depending on the number of CF engines or ICF's. Model R06 with 1 to 4 ICF's has 2 cards and an R06 with 5 to 10 ICF's has 4 cards. Models R16 and R26 normally have 2 cards.

The maximum memory for any G5 model is achieved using 6 GB cards. Systems with 2 cards have a 12 GB maximum; those with 4 cards have a 24 GB maximum.

Minimum memory configuration is determined by using one half of the smallest memory increment (the 1 GB card) capacity. Systems with 2 cards have a 1 GB minimum and systems with 4 cards have a 2 GB minimum.

Memory granularity has been increased; when a maximum memory option of a physical card is reached, cards must be swapped out for larger capacity cards. LIC upgrades require an IML to initialize the new increment of memory and identify the feature properly in the Vital Product Data.

The following table identifies memory increments and physical boundaries. All values are in GBs.

Total System Memory Capacity of 2 Card Models:

| Capacity of | Amount of | (NOTE) | | Physical Card | Memory available | | | (GB) | | | | 1 | 1.0 | | | 1 | 1.5 | | | 1 | 2.0 | (1) | | 2 | 2.5 | | | 2 | 3.0 | | | 2 | 3.5 | | | 2 | 4.0 | (1) | | 3 | 5 | | | 3 | 6 | (1) | | 4 | 7 | | | 4 | 8 | (1) | | 6 | 10 | | | 6 | 12 | (1) | | | | | ------------------------------------------------- | Total System Memory Capacity of 4 Card Models: | | | | | Capacity of | Amount of | (NOTE) | | Physical Card | Memory available | | | (GB) | | | | 1 | 2.0 | | | 1 | 2.5 | | | 1 | 3.0 | | | 1 | 3.5 | | | 1 | 4.0 | (1) | | 2 | 5 | | | 2 | 6 | | | 2 | 7 | | | 2 | 8 | (1) | | 3 | 10 | | | 3 | 12 | (1) | | 4 | 16 | (1) | | 6 | 20 | | | 6 | 24 | (1) |

(1) Boundary point: additional memory capacity requires a hardware replacement.

For stocking and service flexibility a larger memory card may be used to replace a smaller one; Licensed Internal Code (LIC) establishes a logical equivalent. This Generation 5 memory design is new to 9672's (which previously required identical memory cards to be in all positions). Upgrades from 2 card models to 4 card models may have cards of equal physical size if a memory upgrade is required or cards of 2 different sizes if the total system memory is to remain the same.

All Generation 5 models can use the same memory cards. G5 memory cards have an improved design over any previous S/390 memory cards and use the latest fast 64Mb Synchronous DRAMs.

G5 Memory Value and Improved Design: G5 memory scales with the number of processors supported. Models RA6-RD6 are configured with 2 memory cards and hence are known as a 2 bus, or 2 card system. Models R36-YX6 are configured with 4 memory cards and are called 4 bus (or 4 card) systems. Model R06 is configured with 2 cards for configurations with 1-4 ICF's and 4 cards for 5-10 ICF's. Cards have various amounts of memory which can be flexibly used for System memory granularity. Total memory can be ordered in the following GB increments: 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 20, 24. G5 memory card sizes are 1,2,3,4 and 6 GB. Memory can be upgraded in many cases by microcode. It is only when the maximum size of System memory supported by a given card size is exceeded that an upgrade which swaps out cards for higher capacity cards is required. All memory cards are high performance cards. Each card or Primary Memory Array (PMA) contains 8 CMOS 5S memory adapters, 2 CMOS 6S Redrive chips and 64 MB Synchronous DRAM technology. The minimum amount of memory provided with G5 models is 2 to 4 times more than G4 models.

G5 memory design has removed potential bottlenecks which improves throughput and reduces workload variability when compared to G4. The memory interface now handles 4 independent memory requests, one per address bank on the Processor Memory Array (PMA is a card). This speeds data flow. Also by separating the address/command from the data bus potential contention is reduced. Hierarchical Storage Control with the 4 MB L2 in the System Storage Controller (SC) enhances direct controlled memory operations. The SC is designed to support up to 32 GB of main store. This allows expansion of G5's present memory maximum, 24 GB, when required in the future.

The G5 System has approximately 6 GB/sec, 12 GB/sec or 15 GB/sec of memory bandwidth depending on the system model. Models with one processor set (RA6 -RD6) have 6 GB/sec of memory bandwidth. Models with two processor sets (R36 -- RX6) have 12 GB/sec of memory bandwidth. The YX6 model, which runs at the fastest cycle time, is supported by 15 GB/sec of memory bandwidth. Advanced 64 Mb memory technology, multiple memory paths, innovative processor design, advanced memory redrive chips, and fast cycle time combine to give the G5 memory superior performance. Processor design innovations include non-blocking cross-point switching and a dedicated Move Page engine, which significantly improves Main-to-Expanded paging performance.

In addition to improvements for performance, G5 memory has reliability and availability improvements compared to either CMOS or bipolar processors. These improvements include the data bus being Error Checking and Correcting (ECC) protected. G5 memory also has the ability to delete and relocate L1 and L2 data. G5 Main Store and Expanded Store has ECC, background scrubbing, and dynamic sparing of L3/L4 memory which provides memory capable of supporting the extremely reliable CMOS PU sets.



I/O Infrastructure

The Generation 5 models all have been designed to eliminate present and future I/O constraints to running intensive workloads. Given the new milestone in CMOS Server performance, Parallel Sysplex installations should insure maximum data rate capability by installation of full speed InterSystem Coupling (ICS) fiber optic links (100 Mbytes/second). These links exploit full configuration ability and maximum flexibility in conformance to world-wide telecommunications standards. The ISC link uses Long Wavelength laser (1300 nm.) Single-mode fiber (SMF) and operates at 106.5 Mbit/second. This technology enables parallel sysplex configurations connections from several meters to distances up to 10 km.

G5's I/O infrastructure's bandwidth has been increased by over 100%.

  • G5's number of STI connections has doubled from G4 with up to 24 STIs now available.

  • The bandwidth of each STI has increased from G4's 250 MB/sec to 333 MB/sec (bidirectional).
G5 is designed to handle the higher bandwidth of the future.

Introducing the S/390 FIbre CONnection (FICON) Channel: FICON brings to the customer a new High-performance I/O channel, optimized for efficiency at high-speed. At the same time, it provides customers with investment protection, system balance, and coexistence with today's parallel, ESCON TM, OSA, and clustering link technologies. This is an evolutionary step for S/390 -- not one of revolution. FICON takes advantage of the ANSI Fibre Channel Standard transport with the introduction of a performance-enhanced S/390 layer.

FICON's high performance can help meet the needs of evolving workloads of network computing, business intelligence, and other new applications. The high performance also supports the improvements in device transfer rates when future FICON-compatible devices are natively-attached to a FICON channel.

Each FICON channel is capable of supporting more than 4000 I/O operations per second, which allows each channel to support the same capacity as up to 8 ESCON channels. The channel link speed is 100 MB per second full duplex compared with 17 MB per second simplex with ESCON links. The full duplex nature of FICON channels permits them to read and write data concurrently on the same link.

FICON channels achieve these capabilities in a manner which also permits intermixing of large and small I/O operations on the same link, a significant enhancement compared with ESCON channels. Configurations can be thought about in a different manner because of the increased I/O rate, increased bandwidth, and multiplexing of mixed workloads.

FICON's high I/O rate and bandwidth permits channel consolidation by increasing total system I/O capacity. This I/O capacity increase permits growth of single images and logical partitions. Up to 12 FICON channel cards are initially supported on G5.

The 9032 Model 005 Director will be the first product to support FICON through the use of a bridge card and is intended to provide investment protection for currently installed ESCON control units. Up to 16 bridge cards will be supported on a single 9032 Model 005, with each card capable of supporting up to 8 concurrent ESCON control unit connections. Control units can be connected to the system using both FICON (through the bridge card) and ESCON, preserving the customer's investment in all ESCON Directors, as well as the investment in the existing fiber infrastructure. In addition, the performance-enhanced S/390 layer preserves the investment in software which creates channel programs, for control units attached through the bridge card and future natively-attached FICON control units.

The new FICON channels are bigger and faster, supporting the characteristics of both existing and evolving workloads as well as the higher-speeds of new and future devices. But FICON is not just a bigger, faster channel. FICON doesn't provide you with more channels, it provides you with better channels that improve system balance while permitting single image or partition growth, and support mixed workloads on the same channel.

With their improved capabilities, the new FICON channels enable easier Server Consolidation, New Application Growth, large Business Intelligence queries, and exploitation of Network Computing.



G5 Parallel Sysplex Improvements

The Generation 5 CMOS Servers offer the most substantial cluster technology enhancements of any IBM S/390 server introduced to date. The G5 Server Internal Coupling Facility (ICF) is the most powerful CF Uni- processor yet and is key to the Parallel Sysplex technology integration strategy. The new 9672 R06 standalone coupling facility is the most is the most powerful CF in terms of uni-processor and CEC capacity, as it supports up to 10 ICF processors. The R06 is directly upgradeable to 9672 G5 Server models; it also supports the new Integrated Cluster Bus (ICB). The ICB is the core of the Parallel Sysplex Integrated Cluster, offering both improved CF interconnect bandwidth and dramatically reduced command latency to/from the CF. With the ICB technology, IBM S/390 clustered systems will be able to scale in capacity without incurring additional overhead as the individual processors increase in engine speed with each successive processor generation. The G5 Server also introduces support for the Internal Coupling channel (IC), which is a Licensed Internal Code supported "linkless" coupling channel between CF LPARs and OS/390 (TM) LPARs on the same CEC. The IC eliminates the overhead associated with LPAR-simulation of CF Coupling links previously supported via the Internal Coupling Migration Facility (ICMF). Other significant Parallel Sysplex enhancements introduced on the G5 Servers include the Enhanced Parallel Sysplex Clock functions, introducing new instructions supporting a sysplex-wide unique store clock function and support for setting different local TOD values on separate sysplexes connected to the same ETR enabling Multi-CEC Year 2000 Sysplex testing.

Internal Coupling Channels: In March 1999, the ICF or a coupling partition in G5 servers will be able to use the Internal Coupling (IC) channel to communicate between CF and ICF logical partitions and an OS/390 logical partition within a system. Model G5s using an IC channel instead of a HiPerLink channel, installations may improve overall performance of workloads in a Parallel Sysplex by up to 5%. The IC function is implemented in Licensed Internal Code (LIC) to improves reliability while reducing configuration complexity. Each IC channel is identified by 2 CHPIDs, one for sending and one for receiving. ICs have excellent performance, of up to 6 GB/sec, and can run both test and production workloads. The IC is not limited to ICFs, and can also reduce the dependency on the Integrated Coupling Migration Facility (ICMF). Up to 32 coupling connections can be supported by G5 models. ICs can use heretofore hidden CHPIDs (physically blocked), a significant value and benefit to customers nearing the 256 CHPID limit.

Finally, the IC has significant value beyond its performance characteristics; LPARs using ICs to communicate internally within a CEC (either CR LPARs or OS/390 partitions) can simultaneously use External Coupling Links or ICBs to communicate with CFs or OS/390 systems external to the CEC. This flexibility eliminates the need to "wrap" a coupling link to the same CEC to communicate internally, if external communication from the same partition is also required. This capability removes the restrictions associated with ICMF, and improves internal communication performance to the CFCC LPAR, or ICF.

Inter System Channel (HiPerLink) Enhancements: Single mode (SM) HiPerLinks have now been qualified to be used up to 10 km, (equivalent to FICON). An RPQ is available for distances up to 20 km. HiperLinks can pass data up to 100 MB/sec.



Enhanced Parallel Sysplex Clock Function:

Effective March 31, 1999, the Enhanced Parallel Sysplex Clock function will be available, including:

  1. A 128 bit TIME OF DAY (TOD) clock, which enables sufficient clock resolution for future servers; without this facility, future servers would be constrained in how fast they are allowed to process instructions which return a TOD clock value. Another benefit of the 128-bit TOD is A Sysplex unique store clock, useful to applications requiring a unique value, such as a time stamp, across the sysplex.

    Note: 64 bit TOD continues to be supported (existing applications will not be impacted by this improvement).

  2. LPAR Sysplex ETR support, to enable customers to run different sysplexes on the same hardware platform with each sysplex using a different time zone. This capability enables Year 2000 testing on multiple CEC Sysplexes. Also, via a common ETR, this function allows customers to attach separate CECs operating at different local TODs, to operate off the same ETR.



Integrated Cluster Bus (ICB)

The ICB is the core of the Parallel Sysplex Integrated Cluster, offering both improved CF interconnect bandwidth and dramatically reduced command latency to/from the CF. With the ICB technology, IBM S/390 clustered systems will be able to scale in capacity without incurring additional overhead as the individual processors increase in engine speed with each successive processor generation. This feat is accomplished by implementing the coupling link protocols directly in hardware and exploiting an Self Timed Interconnect (STI) to STI memory bus interconnect between G5 CECs in the Integrated Cluster.

Next to the data rate of the linkless IC is the ICB. The ICB uses G5's 333 MB/sec STI to perform the S/390 coupling communication between G5 Servers. Highly integrated with very few parts the ICB is extremely reliable. Compared to a HiPerLink the ICB is a higher performing link. The 10 meter ICB cable can be used between G5 systems up to approximately 7 meters. By enabling data packets to efficiently be identified, processed and stored directly into memory the ICB is able to effectively utilize most of the high bandwidth of the STI bus (effectively 280 MB/sec of the 333 MB/sec bandwidth). The data rate improves performance by reducing the latency of synchronous send messages. This reduction in latency reduces the time a processor is idle and improves Parallel Sysplex performance, resulting in improved workload throughput. When compared to HiPerLinks ICB's, may reduce the overhead associated with coupling Systems in a Parallel Sysplex up to 3%. For example, a Parallel Sysplex incorporating a G5, with the majority of applications participating in data sharing with HiPerLinks running at 90% efficiency may be improved to 92% by use of ICB's, compared to HiPerLinks on G5. ICBs are bi-directional. ICBs will significantly reduce the cost of entry and improve the scaling of capacity in Parallel Sysplexes.

Model R06 has up to 24 STIs to connect ICBs, with a resultant reduction in the available number of channels, as ICB usage increases. The following tables identify the use of ICB's, the number of CHPID's that are reserved by their use, the remaining STI's that can be used to connect to I/O cages, and the ESCON channel maximum.

Maximum Configurations with ICB Connections: Models RA6-RD6: Models RA6, R16, RB6, R26, RC6 and RD6 have 12 STIs. Six STIs are reserved for channels, allowing these models a maximum of six ICBs.

Maximum Configurations with ICB Connections: Models R36-YX6: Models R36, R46, R56, R66, R76, R86, R96, RX6 and YX6 have 24 STIs. Six STIs are reserved for channels, allowing these models a maximum of 18 ICBs.

To summarize this section, all Generation 5 models can have up to 32 coupling connections. Models RA6-RD6 can have up to a maximum of 6 ICB's. Models R36-YX6 can have up to 18 ICB's. Model R06, a dedicated coupling model with no ESCON, FICON, Parallel, or OSA-2 channels, can have up to 24 ICB's. A total of 32 links in combination of HiPerLinks, ICB's and IC's is possible on any G5.



Coupling Facility -- Options

An IBM Coupling Facility (CF) is always defined as a PR/SM LPAR partition. For a 9674 or a 9672-R06, only coupling-facility partitions may be defined. For all other 9672 machine types, both OS/390 and CF (that is, sender and receiver) partitions may be defined on the same machine. Sender and receiver partitions may additionally be defined as enabled for the Integration Coupling Migration Facility (ICMF).

Depending on the 9672 model, the CF processors defined to a particular CF partition may be dedicated internal-coupling-facility (ICF) processors, dedicated central processors (CPs), shared CPs, or dedicated ICF processors and shared CPs (dynamic ICF expansion). When CPs are defined, the customer is subject to software charges for all MSUs or the models software group, including the engines which may be doing the coupling activity. ICF processors are not subject to this charge.

There are four types of coupling links available, depending on the machine type and model: ISC, HiPerLink, ICBs, and ICMF links. The choice of links is dependent on configuration, distance, and performance requirements. ICMF links may only be used when the sender and receiver partitions are both enabled for ICMF and they are on the same physical machine. In this configuration, no other coupling links are available for these partitions.



Internal Coupling Facility (ICF) Value, (Feature #0991)

The ICF, which utilizes a spare Processor Unit (PU), can be a Coupling Facility option. ICF, introduced on G3, extended on G4 in quantity and function, grows in value with its implementation on G5. Most G5 models will be able to configure ICF's on them. Only on G5 models that do not have any extra spare PUs is the ICF feature not offered (models RD6, R96, RX6, YX6 have 0 ICF's). In April of 1998 the maximum number of ICFs on G3/G4 was increased to 4 (based on number of PU's not used). G5 can have more ICFs than either G3 or G4. Up to 7 ICFs in the R36 and up to 10 on the R06 can be configured. Effective March 1999, the maximum number of ICFs will be increased to 8; models RD6 and R96 will have the option of being configured with 1 ICF (no spare PU).

As an option to reduce Coupling Facility cost of ownership, the ICF has both characteristics of a 9672 CF and a stand alone CF. Because the ICF is a CF partition configured to run on only the spare processor(s) of a 9672, it shares the exclusion of software license charges like the R06 or a 9674. Coupling capacity that does not incur software charges lowers the cost of configuring systems in a Parallel Sysplex. By using the Server's infrastructure (power, cooling, mechanical, memory, logic, service element) for coupling, an ICF reduces the power, cooling and space costs versus what a standalone Coupling Facility such as a 9674 or a R06 would be. An ICF also has reduced maintenance charges over a standalone Coupling Facility which has thousands of parts to maintain in addition to the Coupling Facility Control Code. The reduced maintenance price of an ICF reflects the lower maintenance required by an ICF, over a Stand Alone Coupling Facility (9674 or R06).

When using an ICF as a Coupling Facility, it is advantageous to have 2 or more OS/390 partitions to take advantage of continuous operations protection from software outages. Individual OS/390 partitions can be taken down for maintenance or OS/390 release upgrade, without suffering application outage. This is done through data sharing provided by the remaining LPARS in the System.

Dynamic ICF expansion allows an ICF logical partition to acquire additional processing power from a pool of shared CP's executing normal OS/390 production or test work for the system. This has been called an L shaped LPAR for CF's. This capability makes the ICF an ideal backup for either a standalone coupling facility or another Systems ICF(s) which may have more coupling capacity. If an ICF processor fails, even running dedicated, a spare PU can be dynamically switched in to substitute for the failed processor, transparent to the CFCC Licensed Internal Code running on that processor.

G5's ICF is attractive for both test and production workloads. G5 has improved coupling connections. One in particular, the Internal Coupling (IC) channel is ideal for an ICF's coupling to the OS/390 partition(s) inside the same CEC with more efficiency than any other coupling link. The linkless IC couples with more efficiency and in a more cost-effective manner than physical channels because there is no set up for LPAR code or coupling links. The IC reduces the cost of Parallel Sysplex while improving its performance. G5's other new coupling connection, the Integrated Cluster Bus (ICB), has approximately 280 MB/sec bandwidth or 3 times the maximum bandwidth of the improved coupling links on G3 and G4, HiPerLinks. ICB's connecting G5's and the use of ICF's reduce the cost and complexity of Parallel Sysplexes while improving performance.

ICF's are ideal for coupling Resource Sharing, or Systems Enabled Parallel Sysplexes; sysplexes that are not in production data sharing with IMS (TM), DB2 (R) or VSAM/RLS. Simplified systems management can be achieved by using XCF structures versus ESCON Channel to Channel connections. Improved scalability is possible while Systems Enabled when either GRS STAR or RACF (R) is used. With GRS Star, the traditional ring mode protocol for enqueue propagation is replaced by a star topology where the CF (or ICF) is the hub. By using the ICF and GRS STAR, enqueue service times can be reduced up to 10X. RACF can leverage command propagation in a Sysplex to refresh each System's copy of the RACF database. One step further is when RACF caches its entire database in the CF. This provides high speed access to security profiles.

ICF's such as either a standalone R06 or a 9674 Coupling Facility need configuration planning must still account for memory and links. ICF's will likely increase memory requirements, especially if software exploits the CF to provide additional function not available except when running a CF in a Parallel Sysplex.

A production Systems Enabled environment with 2 ICF's will not compromise sysplex availability or integrity. The following is an example or 2 systems each with an ICF:

| System 1                       System 2     |
|----------------.             .--------------|

| JES2           |             |              |

The combination of an ICF and the following software in a Systems Enabled (Resource Sharing) Parallel Sysplex produces significant benefits to customers without full datasharing as noted in the following table:

For the present, 2 ICF's are the preferred solution for Resource Sharing Parallel Sysplexes and either 2 Standalone CF's or 1 Standalone CF and an ICF for backup are the preferred solution for full data sharing (IMS, DB2, VSAM/RLS) Parallel Sysplexes.

One of the latest innovations is the G5 capability to upgrade a coupling ICF to an Application CP. This chargeable PU upgrade has the effect of "removing the ICF": it allows a customer to buy to buy another ICF on a different system, at standard pricing, to effectively remove an ICF and install an ICF on another machine. Conversely, the G5 has the capability to convert an Application CP to an ICF via an MES, when CF consumption of the Application CP is high enough to warrant conversion to a dedicated ICF processor (this action may avoid on-going software license charges on that processor).



9672 Model R06 Value

The R06 is an option that a customer may use to define Coupling Facility partition in a standalone environment. For Application Enabled (data sharing) Parallel Sysplexes it is strongly recommended that one or two R06's be utilized. The 9672 R06 has the flexibility of operating similar to a 9674 dedicated coupling facility today and in March 1999, upgrading to another Generation 5 Server. The R06 uses the latest level of Coupling Facility Control Code, CFCC.

A standalone coupling facility assists configuring a Parallel Sysplex to be resilient to failure. This means that the loss of a Coupling Facility would not force recovery of CF resident data through the use of logs or even lose data where no logs exist. Recovery through use of logs is a lengthy process and may take hours, so a standalone CF (either 1 or 2) are needed for the Application Data Sharing environment.

All of the R06's resources are devoted to coupling. As a standalone CF it can be independently upgraded with minimal planning and not impact production workloads. The R06, not running OS/390 or customer workloads, has value not only in physical isolation that dedicate 100% of its resources to coupling, but it also saves software costs by not being charged for running applications; moreover, the R06 is consistent with the objective for CMOS Servers (with ICF's) being Cross Connected (mutually supporting) and capable of all the functions on today's standalone CF's.

The R06 has more coupling and link capacity than any other CF. R06's can scale to 10 coupling engines, more than the next highest model, the R36's 7 ICF's (increases to 8, effective March 1999). The R06 also can attach up to 24 ICB's and have up to 24 GB of memory (memory capacities in GB are: 1, 1.5, 2. 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 16, 20 and 24 GB). The types of coupling connections on R06 include ICBs and HiPerLinks.

9672 Model R06 Minimums and Maximums: The 9672 R06 model replaces 9674's as a standalone Coupling Facility. R06 hardware is dedicated to the coupling tasks. R06's are not charged for OS/390 or application software. The R06 uses the same technology as other Generation 5 models. Because there is no need for Parallel, ESCON, OSA-2 or FICON Channels, the R06 has the ability to scale Integrated Cluster Busses, the new G5 Coupling connections higher.

The following table compares and contrasts features of the R06 with the other G5 Models:

Note: Although 32 pairs of ICs can be configured (for a total of 64 sending and receiving required) it is not recommended as ICs have high bandwidth and large numbers of ICs are not necessary.

(*) The 3 channel minimum only applies to MES's that bring forward the older 3 port parallel channel card or systems shipped in 1998 prior to availability of feature 2304 (4 port parallel card). All new build G5's have 4 port Parallel and ESCON cards and their minimum is 4 channels. It is important to realize that I/O options are not additive to the 256 channel connections. There is a reduction in 256 ESCON channel maximum for each Parallel channel card, OSA-2, IC, ICB, HiPerLink or FICON connection.

The use of PU's for SAPs and spares is also different for the R06. Every R06, 1way to 10way, has a spare PU; All R06's have a single SAP. Models RX6 and YX6 have no spares. Models R86, R96, RX6 and YX6 have as standard 2 SAP's to drive the larger I/O workloads associated with 8 or more processors. R06's are plugged like other 9672 G5 models to minimize CHPID disruption (changes) when upgrading from an R06 to other Generation 5 models.

Memory increments for R06 and other models are identical. Upgrades to model 9672 R06 from 9674 models C04 and C05 are available September 30, 1998; upgrades of model R06 to the other G5 server models will be available March 31, 1999, introducing new flexibility to preserve asset value. Future upgrades of R06's will be tied to the model structure and option limits of the model the R06 is upgrading to. R06's have their I/O plugged like other 9672 R6's in order to minimize CHPID changes. Deviations to plugging rules require an RPQ.



Significant New S/390 Architecture Instructions

S/390 G5 Parallel Enterprise Server architecture has 121 new hardware instructions beyond prior S/390 CMOS models. Major categories of instructions include:

  • Hardware implementation of IEEE Floating Point Arithmetic: This enhancement supports the common IEEE industry standard*, with 16 floating point registers, compared to the present 4 registers on prior models of S/390 hardware. In conjunction with OS/390 Version 2, Release 6, customers may observe the following benefits:
    • Improved performance for Java applications using floating point operations. With former support provided by software emulation, this new hardware enablement optimizes performance, while remaining compliant with the Java specification for floating point support.

    • Improved performance for C/C++ programs recompiled to allow usage of the additional floating point registers, including programs using current S/390 floating point.

    • Simplified porting of C/C++ applications from other platforms to OS/390.

    • Simplified porting of DOMINO Companion Products to OS/390.

    • Enhanced S/390 support for OPEN Standards.
    Java floating point performance will be improved by the use of the new architecture instructions in new releases of the Java Virtual Machine and "JUST IN TIME" (JIT) Complier available in March 1999.

    Java is a Trademark of Sun Microsystems Inc. (*) ANSI/IEEE Standard 754-1985, IEEE Standard for Binary Floating-Point Arithmetic.

  • Year 2000 Support: Instructions have been added to accelerate execution of:Runtime Analyzer for MVS (TM) and OS/390 and Millennium Runtime Windowing Tool. These application remediation tools help find and fix year 2000 date exposures in: Batch, Started Tasks (STCs), CICS (R) and IMS application code.

The Processor Resource/System Manager* (PR/SM*) facility of the G5 Server family has been submitted for evaluation against the Information Technology Security Evaluation Criteria (ITSEC) at an E4 assurance level. The evaluation is being conducted in Germany by the IABG CLEF.

The E4 level provides a very high degree of assurance that PR/SM can be used in environments where separation of workloads is a requirement, but where the use of a single hardware platform is desirable for reasons of economy, flexibility, security, or management. PR/SM provides for secure isolation by preventing the flow of information among partitions. This isolation may be used where the separation is based on need to know, or where data at differing security classifications must be isolated.

This certification validates the G5 processor as an essential building block for business solutions integrating e-Business applications and traditional corporate workloads on a single platform.

The certification is expected to be completed in fourth quarter 1998.

Cryptographic Coprocessor: IBM's leading edge Cryptographic Coprocessor is the world's fastest dedicated cryptographic engine for scientific and commercial workloads. The highest level of security for protecting information , Triple DES, is now available worldwide using IBM's S/390 CMOS Cryptographic Processor.

The S/390 CMOS Cryptographic Coprocessor is exportable and is enabled by a unique diskette that is linked to the systems's individual serial number. Cryptographic coprocessors are standard on every G5. Every G5 model is built with 2 cryptographic coprocessors. Even model R06 has 2 Cryptographic coprocessor chips which can be enabled if the R06 upgrades to other models. G5's crypto chips are tamper proof. G5's crypto engines support a variety of cryptographic standards including 40, 56, 112 and 168 bit algorithms for protecting information.

Public keys standards RSA and DSS (DSS is used in many U.S. Government bid specifications) are supported.

The following new functions announced on February 24, 1998, for the Generation 4 are also available on Generation 5 to enhance IBM's commitment to Network Computing Framework (NCF) including the security for IBM's Net.commerce initiatives, emphasizing e.commerce.

These new functions available with OS/390 V2R5 are:

  • SET Support

    Secure Electronic Transaction (SET) is a protocol developed jointly by VISA International and MasterCard for safeguarding payment card purchases made over open networks. It has become pervasive in use by e-commerce as a transaction protocol and software vendors are incorporating SET into existing browsers and merchant servers.

    ICSF has been enhanced to include support for SET by implementing RSA-OAEP encryption. This support will enable vendor and user-written applications to take advantage of the integrated crypto capabilities of S/390. This includes:

    • Superior performance from using crypto hardware for hashing, encryption and signature functions.
    • More efficient implementation of OAEP formatting and encryption/decryption (which is required by the SET protocol).
    • Security for DES keys and application RSA keys because they will not appear in the clear.
  • Support for CVV and CVC

    VISA and MasterCard have specified a cryptographic method to calculate a value that relates to information on a payment card such as the personal account number (PAN), the card expiration date, and the service code. The use of card-verification values (CVV) can reduce the risk of losses resulting from alteration/counterfeiting of the card's magnetic stripe.

    ICSF has been enhanced to provide callable services to generate and verify the VISA card-verification value (CVV) as well as the MasterCard card-verification code (CVC) using the track-2 method. This support provides additional card integrity for financial processes involving payment cards. CVV/CVC functions are available on DES (non-CDMF) systems only.

  • PKA Cryptographic Key Data Set

    ICSF now provides a storage data set for Public Key Algorithm (PKA) private and public keys. Storage of PKA keys within a Public Key Data Set (PKDS) allows existing PKA APIs to specify a record label as an alternative to specifying a key token and eliminates the need for PKA applications to provide their own PKA key storage mechanism. Customers will now be provided with the same security, flexibility and efficiency working with public/private keys as they have had with DES keys.

  • Zero Pad for DES Key Exchange with RSA

    Padding using zeroes as an alternative to padding according to Public Key Cryptography Standard (PKCS 1.2) is now available when using the Symmetric Key Generate, Symmetric Key Import, and Symmetric Key Export functions. The services will each allow for and process a new keyword, ZERO-PAD, in the rule array.

  • Double-Key MAC Support

    The ANSI X9.19 Optional Double-MAC Procedure is supported by ICSF. This requires the use of a double-length key for MAC processing. This support addresses customer requirements for enhanced security for message authentication. Emerging VISA International and MasterCard protocols in Europe also call for ANSI X9.19 MAC. Generation of both user derived keys and SESSION MAC keys will be supported.

  • Triple DES (TDES)

    DES encryption for ICSF has been enhanced to now include TDES (168 bits) encryption. This availability of strong encryption provide customers with increased flexibility in choosing the level of data encryption they desire. Finally, the TDES performance of the G5 has been significantly improved over the performance observed on G4 models.



Exploitation

Application and Product Utilization of Hardware Encryption: There are a number of different applications, products and communication protocols which rely on encryption to offer data confidentiality for protecting sensitive information and data integrity for ensuring information accuracy. In addition, many international standards and defacto standards have architected secure communication options based on encryption such as:

  • Secure Electronic Transactions (SET)
  • Secure Sockets Layer (SSL)
  • Secure Hypertext Transfer Protocol (SHTTP)
  • Internet Protocol Security (IPSec)
  • DCE Remote Procedure Call (RPC)
  • SNA Session Level Encryption (SLE)
Exploiters of S/390 hardware encryption include:
  • CommercePOINT (TM) uses encryption to implement Secure Electronic Transactions to protect electronic business credit card communication between consumers, merchants and banks.

  • Domino (TM) Go Webserver (previously known as Internet Connection Secure Web Server ICSS) offers Secure Sockets Layer (SSL) encryption to protect communication between web clients and web servers.

  • OS/390 Firewall Technology supports IPSEC to provide firewall encryption "tunneling" which creates virtual private networks (VPN) in intranet or internet environments using DES or triple-DES.

  • DCE Security Server implements secure Remote Procedure Calls (RPC) using encryption for data integrity and confidentiality in UNIX (R) TCP/IP communications across networks.

  • VTAM supports SNA Session Level Encryption (SLE) which is used by applications such as DB2 and CICS to communicate securely across networks using DES encryption.
IBM has worked with RSA to enhance BSAFE 3 to allow software applications to determine if encryption hardware is available on the runtime platform and invoke the supported encryption calls for DES, random number generation, MD5 and SHA-1 digest, and RSA signature generation and verification. This support allows other vendor applications to easily exploit the faster hardware encryption available on S/390 platforms.

Migration/Coexistence Considerations: When migrating from ICSF V1.1 to ICSF V2.1, one must first migrate the CKDS to the current format. A migration utility called CSFCVR1 is provided. The utility can be run on either ICSF V1.1 or on the latest release.

When migrating from ICSF V1.2 to ICSF V2.1, no migration is necessary but new system keys must be defined for CKDS if new key functions are to be used. Once new system keys are added to CKDS, CKDS is not sharable with ICSF systems which do not support those key types.

ICSF V2.1 PKA implementation differs in some respects from the implementation in the Transaction Security System (475x) products.

  • ICSF does not support PKA92.
  • ICSF does not support RSA Key Generation.
  • TSS does not support the FIPS 186 (DSS) standard.
There are no changes for the Trusted Key Element (TKE) unit.

In the S/390 G5 Server, TDES support is in LIC Driver 10 and beyond. The S/390 G5 Server joins the G4 as the only two processors supporting TDES for privacy.

Requirements: These enhancements require OS/390 V2 R5 and beyond.

Export Considerations: As with the previous announcement in June 1996, regarding the CMOS Cryptographic Coprocessor, an enablement diskette will be shipped with the server to customers who decide to enable the Crypto Coprocessor.

Customers located within the USA and Canada can receive TDES functionality.

Banking and Finance customers located outside the U.S. and Canada can receive TDES under a blanket licensing agreement that IBM has with the U.S. Dept. of Commerce. All other customers outside the USA and Canada must have an export license in order to be given this level of encryption. In all cases, contact your IBM Export Regulations Office for specific guidance.

S/390 Open Systems Adapter 2

One S/390 Open Systems Adapter 2 (OSA-2) is shipped with each S/390 G5 Parallel Enterprise Server providing seamless, scalable connectivity to Local Area Networks (LANs). The OSA-2 feature plugs into an I/O slot and has the same reliability and availability characteristics of a S/390 channel. Any of the media types can be selected up to a maximum of 12 features for each G5 Server. The selectable features are as follows:

  • The Ethernet/Token-Ring (ENTR) feature has two independent ports which can be configured as either Ethernet or Token-Ring. The ENTR feature supports full duplex/switched environments permitting a simultaneous transmit and receive for an effective throughput of up to 20 Mbps (Ethernet) and 32 Mbps (Token-Ring). Implementing a switched infrastructure can solve network capacity problems with minimal disruption to the infrastructure, minimizing changes to the wiring closets, building cabling, and software.

  • The Fast Ethernet feature has a single port that automatically adjusts to 10 or 100 Mbps, auto-sensing/auto-negotiation. This feature supports shared or switched, half or full duplex environments. SNA/APPN (R), TCP/IP, or HPDT MPC (used by HPDT for UDP or High Speed Access Services) are supported concurrently. Fast Ethernet offers familiarity, and coexistence with 10 Mbps Ethernet LANs, while delivering greater bandwidth to the network.

  • The FDDI feature has a single port that supports dual-ring or single-ring attachment as well as attachment to an optical bypass switch. FDDI can be used as a network backbone to connect routers, bridges, and servers. It delivers greater bandwidth than Ethernet or Token-Ring LANs.

  • There are two ATM features supporting attachment to an ATM network; one supporting connectivity to multimode fiber optic cables, and one supporting connectivity to single mode fiber optic cables. The ATM features can be configured in four "modes";
    • ATM Forum-compliant LAN Emulation (ATM LANE) emulating either an Ethernet or a Token-Ring LAN. This allows integration of ATM-based networks and existing Ethernet and Token-Ring LAN networks with as little change as possible while benefiting from the characteristics of ATM technology -- scalability, a consistent protocol across the LAN and WAN, and integration of data, video, and voice traffic

    • ATM IP Forwarding for OS/390 and MVS/ESA (TM) TCP/IP environments, supporting direct connectivity to the Wide Area Network (WAN), allowing consolidation of WAN data traffic and carrying it on a single LAN backbone. This offers more seamless connectivity between the S/390 Server and intranets and the Internet, resulting in faster, less expensive network access to S/390 data and applications.

    • Native ATM for OS/390 High Performance Data Transfer (HPDT) and High Performance Routing (HPR) environments supporting best effort and reserved bandwidth virtual circuits over APPN networks; no changes to applications, reduced management costs, reduced overhead, and the flexibility to negotiate availability, segregate traffic, and provision bandwidth

    • Native ATM for Communications Server OS/390 Version 2 Release 5 environments (classical IP, RFC 1577); IP traffic can be transmitted over ATM networks. Overhead is reduced and administration is less complex compared to running ATM Forum-compliant LAN emulation.

Flexibility to add capacity quickly and efficiently, having a true multiprocessing environment that supports multiple applications and thousands of end users concurrently.
Scalability, Availability, Reliability, Security, Manageability, Data Integrity, and Flexibility combine to define the S/390 state of computing art.



Progress Report: The Transformation of S/390

IBM kept what was right (reliability, scale, availability, security, & manageability), and then shrank it with CMOS, then opened it (UNIX, ATM, CORBA, TCP/IP, IEEE, DCE, Domino, NT, Java, SAP R/3, adapted it Peoplesoft, and so forth), networked it (Domino Go Webserver, NETWORK STATION (TM), and so forth) and clustered it (Parallel Sysplex). We made it self-tuing (Workload Manager) and integrated everything (OS/390) so that it supports the industry growth initiatives (e-business, Server Consolidation, Business Intelligence and Applications. The following sections detail progress:

  • OS/390 -- the flagship operating system for the S/390 platform: Also offers customers the tools they need to conduct business over the Internet. OS/390 is the enabling technology for e-business. OS/390 offers key technologies, including:
    • Domino Go Webserver, is a high performance transaction-processing Web server that works with OS/390's workload manager that delivers just-in-time system resource to address the unpredictable workload demands coming from the Internet. Domino Go Webserver is also the foundation for Net.Commerce V3 for OS/390 e-business application and data connectors to access CICS, IMS and DB2. Java Development Kit (JDK) to address inter/intranet and general business application requirements as well as leveraging current assets, such as existing data and applications.

    • S/390 has a rich set of network connection capabilities that tie internal and external networks directly into the S/390 Parallel Enterprise Server.

    • Open System Adapter supporting multiple network technologies such as: 100 megabit Fast Ethernet support today evolving to Gigabit support; Network load balancing of Internet transactions via ESCON attached 2216 Nways (R), Multiaccess Connector to the S/390 Parallel Sysplex environment to support continuous computing and scalability you can't out grow.

    • More importantly, S/390 and OS/390 offers leading-edge security: OS/390 Firewall Technologies -- provides protection for network applications by controlling user access to specific servers inside and outside a trusted network.

    • Cryptographic Coprocessor -- a hardware-embedded security function for data encryption standards, with the latest models of IBM Parallel Enterprise and S/390 Multiprise (TM) 2000 servers. Transactions secured by the Secure Electronic Transaction (SET) protocol are supported by the S/390 Cryptographic Coprocessor. Digital Certificate support -- part of OS/390 Security Server, helps identify and authenticate users and provide access to OS/390 resources while transacting business over the Internet, intranets and extranets. Auto virus protection mechanisms integrated into OS/390 that protect applications and data from being corrupted.

    • SAP R/3 The database implementation of SAP R/3 on S/390 transparently inherits the datasharing strengths of the parallel sysplex environment. This means that customers can achieve open ended scaling capabilities in the S/390 SAP database environment. In addition to scaling benefits, the availability characteristics of DB2 in a Parallel Sysplex environment are also intrinsically part of the SAP R/3 implementation on S/390. From a flexibility perspective, there are connectivity options of using either OSA-2 or ESCON, and to link in either NT or an AIX (R) application servers. Finally, for existing S/390 customers, the ability to leverage investments in the platform and skills when implementing an SAP solution while gaining the availability and scalability attributes discussed is a very attractive option. A specific example follows: VF Corp, a leading manufacturer of quality apparel products, has completed initial phase one implementation SAP R/3 on DB2 for OS/390.They chose the S/390 platform because: "VF Corp's enterprise are a critical component toward providing quality service to our customers. The reliable and economical support offered by the System/390 (R) with DB2 solution fit well with our requirement for high availability, proven reliability, and flexible scalability. With this solution we have the enterprise-oriented quality and economy of traditional mainframe technologies, as well as the flexibility of client/server technologies to respond quickly and appropriately in the dynamic business environment of today."

    • OS/390 Ease of Use Capabilities for VM and VSE Customers-Future Opportunity for Easy to Use UNIX Application Server

      As a clarification of IBM's October 7, 1997 Medium Sized Enterprise Announced intent to make applications easier to run in a S/390 environment, we are providing the following additional information. Secure Network Computing and e-business, Lotus (R) Domino for S/390, the hottest UNIX based Enterprise Resource Planning (ERP) applications, Server Consolidation of UNIX application workloads, and the ability to run generalized UNIX interactive workloads will now be within easy reach of S/390's Medium Sized Enterprise Customers. This can provide a lower total cost of computing solution for small or departmental solutions in large enterprises.

      For Medium Sized Enterprise Customers, these exciting new capabilities will be enabled and made available via an easy-to-use OS/390 automated UNIX application server which will be available as an additional OS/390 delivery vehicle option. For VM and VSE customers, new offerings similar to the current IBM OS/390 Implementation for VM and VSE Offering will help make this new capability financially attractive. The automated UNIX application server will coexist on the same processor in either an LPAR or as a VM Guest machine with the current VM and/or VSE systems. Existing VM and VSE customer applications can continue to run unchanged. Traditional VM/VSE system programmer and operator skills are required, but, the easy-to-use OS/390 automated UNIX application server's objective is to require no OS/390 (MVS) systems programmer or operator skills to install, maintain or use. UNIX skills for the easy-to-use systems administration interface of the automated UNIX application server, UNIX based ERP applications, and UNIX workloads will be sufficient to manage the applications.

    • G5 Parallel Sysplex Enablement:

      With the Generation 5 CMOS Servers, IBM has improved capabilities of existing Parallel Sysplexes involved in full data sharing of IMS, DB2 and VSAM/RLS workloads as well as migration to Parallel Sysplex.

      Generation 5 coupling engines are larger and have improved price/ performance. R06s and ICF allow granular capacity additions. The new IC and ICB connections, only on G5 models, gives a lower cost of entry to enable Parallel Sysplex configurations in establishments.

      The ICB is the core of the Parallel Sysplex Integrated Cluster, offering both improved CF interconnect bandwidth and dramatically reduced command latency to/from the CF. With the ICB technology, IBM S/390 clustered systems will be able to scale in capacity without incurring additional overhead as the individual processors increase in engine speed with each successive processor generation. Because this combination of ICF/IC performance may be orders of magnitude higher than ICMF, it is recommended that customers use ICF/IC as their entry to Parallel Sysplex configurations, for a smooth transition from test to production.

      Clarified Criteria for Aggregated PSLC pricing

      On January 13, 1998, IBM announced clarified criteria to qualify for aggregated Parallel Sysplex License Charge (PSLC) software pricing. IBM has always required processors to be "actively coupled" to qualify for aggregated PSLC software prices. This announcement adds qualifying criteria to IBM software customer agreements that clarifies what it means to be "actively coupled".

      IBMers and customers have asked for more details of what must be done to qualify for aggregated PSLC prices. The lack of detailed criteria has led to inconsistencies in determining when customers qualify for aggregated PSLC pricing. The objective of this announcement is to clarify the criteria so it can be consistently applied to all customers.

      In addition to having qualifying hardware and software, all processors in a sysplex must be physically attached to a common Coupling Facility and timer. All of the MVS or OS/390 images in the sysplex must have at least one common systems enablement function, of the eleven functions that qualify, activated to use the Coupling Facility across all images in the Sysplex. In addition, this must be the normal mode of operation for the sysplex and the OS/390 and MVS images participating in the above functions must account for at least 50% of the total OS/390 and MVS total workload on each machine.

      Customers currently receiving aggregated PSLC pricing will be given a grace period up to the end of September, 1998 to meet the clarified criteria. Grace periods may be shorter if the customer's implementation is simple. Customers adding new sysplexes must meet the criteria now to qualify. Exceptions to the criteria will be considered for customers committed to a parallel implementation strategy that have valid and compelling reasons for not meeting the criteria. Exceptions will be handled through the software special bids process.

      Scalable price performing coupling engines and connections are part of IBM's commitment to enabling customers to enjoy the benefits of Parallel Sysplex. SOFTWARE LICENSE CHARGES HAVE BEEN MODIFIED TO REFLECT PARALLEL SYSPLEX USEAGE.

  • Network Computing: The IBM S/390 Parallel Enterprise Server is the industry leader for running multiple diverse, mission-critical workloads including online transaction and batch processing, financial and administrative applications, business intelligence and new e-business applications. Industry consultants estimate that more than two thirds of the world's business data resides on IBM Servers, most of it is on S/390.

    S/390 has industry-leading levels of availability, security capacity and reliability for enterprise computing needs. Many of you have heard and know about IBM's e-business strategy. To conduct secure e-business you need:

    • The highest levels of system, network and transaction level security.
    • Quick and accurate delivery of business data and applications.
    • Flexibility to meet unpredictable capacity and performance growth requirements.
    • The highest levels of system availability and reliability.
  • Business Intelligence (BI): is a natural fit for the S/390 platform. The combination of G5 servers and efficient symmetric multiprocessing, along with the scalability of parallel sysplex provides fast parallel performance that grows with a customer's needs. Data mining will benefit greatly from the single CPU performance increases because of the current single process nature of Intelligent Miner (TM) Version 1 . Once we go parallel, the benefit multiplies. One resulting benefit is shorter elapsed time on individual mining runs. Data mining workloads benefit in the same way as other workloads with additional memory capacity. Additional memory above the 2 GB limit is an obvious big benefit; a dedicated Move Page engine in the G5 server will fully exploit large memories.

    BI workloads are resource intensive and at the same time very unpredictable. Short running queries coexist with extremely demanding complex analyses, data mining runs and updates to the warehouse. OS/390 Workload Manager (WLM) is able to manage this diverse workload using business priorities so that the customer service rep's short running query does not wait behind the fraud detection data mining run. WLM is able to deliver guaranteed response time to more important work and distribute the remaining resources among the other work, based upon desired goals and importance. that can terminate important work midstream just because it has exceeded an arbitrary threshold. WLM can be set to automatically downgrade the importance of the work as it ages in the system and prevent it from degrading other queries. Functions like these mentioned enables OS/390 to support many more users than other BI platforms, making its cost /user lower than many UNIX platforms (based on ITG cost of scalability).

    Customers like Edison International are using OS/390 and DB2 to provide themselves with a competitive advantage in the increasingly deregulated utility industry. Edison has been building a warehouse and data marts on OS/390 for a number of years. They have data from many parts of their business (human resources, power usage, customer information, and so forth) in their DB2 BI system. A financial study of one of their data marts (a credit collections data mart) by IDC revealed a return on investment of 662%. Edison makes the BI data available to all their employees using a large variety of tools, both traditional and new (and so forth, SAS) MS Access. They also have web-enabled their warehouse, making it accessible via the intranet. Edison picked S/390 because it enabled them to scale easily while utilizing their existing investment in skills and tools.



S/390 Applications Initiative

The IBM S/390 Applications Initiative is directed toward providing support for customers in three key areas:

  • Enhanced support for existing applications
  • New software technology to enable new applications
  • Applications new to the S/390 platform
Robustness of the S/390 platform is key to success in each of these areas. Following are instances of how OS/390 and the S/390 hardware, including the new G5 processor and I/O enhancements, support these areas.



Enhanced Support for Existing Applications

Support is provided by both hardware and software improvements:

  • G5 functions which improve the performance of key UNIX Services functions: An example is the exploitation of the Perform Locked Operation (PLO) instruction which is used to reduce system contention when operations need to be serialized across several CPUs. UNIX System Services has been able to take advantage of this instruction to improve performance for applications like Domino for S/390. Further use of PLO is being investigated for other aspects of OS/390.

  • Software improvements: With the successful UNIX branding of OS/390, there is now a large scale development effort addressing a wide range of UNIX System Service performance areas. With OS/390 R5 the entire TCP/IP stack has been re-written to dramatically reduce pathlength, improve SMP scalability and overall performance. Enhancements to the Hierarchical File System (HFS) improved small file access and cached read performance in OS/390 R4. Pending in OS/390 development is restructuring to improve all aspects of file performance providing an order of magnitude improvement in response time. Similar efforts are underway with NFS with major performance enhancements being developed in OS/390.

    The C/C++ compiler on OS/390 continues to utilize the latest levels of IBM optimization technology for each of its new releases and improvements have been made to DLL processing. Enhancements in the Kernel and Run Time Library (RTL) have significantly improved the integration of Unix services within the operating system and reduced the overhead to invoke these services by 80% between OS/390 R3 and R4 and by an order of magnitude from the early POSIX releases. Web serving throughput has increased by 100 fold since the first release of the Internet Connection Secure Server (now called Domino Go WebServer) and continued large scale performance enhancements are planned for 1998 and 1999.



New Software Technology to Enable New Applications

The performance of open connectivity to DB2 is greatly improved with DB2 5.1 through the implementation of Store Procedure Calls under Work Load Management (WLM), native TCP/IP sockets, improved dynamic SQL processing, and the avoidance of ASCII/EBCDIC translation. In addition, profiling tools are being created to assist in performance optimization of C/C++ applications.

With the above combination of pathlength scrubbing, reduced layering, component restructures, and new hardware instructions, we anticipate large improvements in overall end-to-end S/390 UNIX performance in 1998 and 1999.



Applications New to the S/390 Platform

A variety of new applications have become available on S/390 and OS/390 in recent months. Key among these is SAP R/3, which is one of the leading Enterprise Resource Planning (ERP) applications. These enhancements continue to support UNIX applications on OS/390. In particular, the increased capacity of the new G5 processor and its associated I/O subsystems will provide improved performance for SAP R/3.

In addition, the database implementation of SAP R/3 on S/390 transparently inherits the datasharing strengths of the parallel sysplex environment. This means that customers can achieve open ended scaling capabilities in the S/390 SAP database environment. In addition to scaling benefits, the availability characteristics of DB2 in a parallel sysplex environment are also intrinsically part of the SAP R/3 implementation on S/390. From a flexibility perspective, there are connectivity options of using either OSA or ESCON, and to link in either NT or AIX application servers. Finally, for existing S/390 customers, the ability to leverage investments in the platform and skills when implementing an SAP solution, while gaining the availability and scalability attributes previously described make an extremely attractive solution. The IBM S/390 Parallel Enterprise Server (TM) is the industry leader for running multiple diverse, mission-critical workloads including online transaction and batch processing, financial and administrative applications, business intelligence and new e-business applications. Industry consultants estimate that more than two thirds of the world's business data resides on IBM Servers, most of it is on S/390.

S/390 has industry-leading levels of availability, security capacity and reliability for enterprise computing needs. Many of you have heard and know about IBM's e-business strategy. To conduct secure e-business you need:

  • The highest levels of system, network and transaction level security.

  • Quick and accurate delivery of business data and applications.

  • Flexibility to meet unpredictable capacity and performance growth requirements.
Another example of new technology is Component Broker: In May of 1997, IBM announced the plan to deliver its object-oriented application development environment. Component Broker was announced as rolling out over time on multiple platforms.

With OS/390 Version 2, IBM will follow through on that announcement and deliver Component Broker on the S/390 platform. Initially, this will be done for a limited set of customers participating in concept validation on OS/390 Version 2 Release 5. At the conclusion of concept validation, Component Broker for OS/390 will be orderable no-charge for those customers with OS/390 Version 2 Release 5.

Component Broker for OS/390 will provide an environment for the hosting of new business applications on S/390 that, using a new programming model, will enable customers to rapidly design and develop their applications. This programming model will be the same across platforms.

Component Broker for OS/390 will leverage S/390 strengths such as Parallel Sysplex technology for scale and availability, and will exploit the OS/390 Workload Manager for proper workload balancing and management. This will enable Component Broker work to run along with traditional workloads such as IMS and CICS.

The G5 server with its increased I/O bandwidth and the FICON strategy will provide added robustness to the overall object-oriented environment on S/390.

Parallel Sysplex -- Introducing the GEOPLEX

The GEOgraphically dispersed parallel sysPLEX (GEOPLEX) is a parallel sysplex spread across 2 or more sites up to 40 km apart; all critical data is remote copied between the sites. The GEOPLEX provides the capability to manage the remote copy configuration, and storage subsystem, in addition to being able to automate planned reconfigurations or failure recovery from a single point of control. The GEOPLEX supports all TP monitoring (such as, CICS & IMS, and all DB managers (for example, DB2, IMS, & VSAM). In the event of a planned system or site shutdown, GEOPLEX will quiesce affected workload (and optionally restart it elsewhere), while the workload continues to execute on other nodes. In the event of a site or system failure (for example, a disaster), GEOPLEX will restart the failed workload on surviving nodes, while work continues to execute.

IBM has proven this concept with multiple Joint Customer Studies including IT Austria, the newly formed IT Subsidiary of Bank Austria, Creditanstalt, Erstebank, and Spardat in Vienna, Austria, establishing a dispersed, multi-site environment for application programs using facilities enabled with:

  • IBM's Parallel Sysplex

  • Systems Automation for OS/390

  • PPRC (Peer-to-Peer Remote Copy)

  • Model 9729 (for GEOPLEX implementation beyond 20 km).
Note: The IBM 9393 RAMAC (R) Virtual Array model T8L is being significantly enhanced with the addition of Peer-to-Peer Remote Copy (PPRC) support.

A White Paper, "GEOPLEX, a Multi-Site Availability Environment for Application Programs" that details IBM's approach to satisfy continuous availability solutions, is available from your IBM Marketing Representative, or can be downloaded from the Internet URL:

IBM has developed a set of tailored services presently under controlled availability, to customers who have the requirements necessary for evolution to the GEOPLEX environment. Contact your IBM representative for participation details.



STATEMENT OF GENERAL DIRECTION

  • Fiber Optic data throughput, type & quantity of ISC links: IBM intends to offer higher speed links using Single Mode Fiber (SMF) optics, conforming to telecommunication standards, to meet customer requirements of gigabit and multi-gigabit data rates, increased system performance and flexibility of hardware placement. IBM also intends to withdraw from Marketing Multi-mode Fiber (MMF) ISC links.

  • New Open Systems Adapter Feature: High-speed network connections in the server are essential as the quantity and size of data files transmitted over the network increases in support of intranet and Internet traffic, as well as imaging, data warehousing, and backup applications.
    • IBM intends to offer a new feature supporting Gigabit Ethernet (GbE), a 10X increase in media speed over the current 100 Mbps Fast Ethernet OSA-2 feature. This new GbE feature will plug directly into a standard I/O slot, and will be compliant with the IEEE 802.3z standard.

    • IBM also intends for a future release of eNetwork (TM) Communications Server for OS/390 -- IP Services to deliver a new mechanism for network communications, supporting the new GbE OSA feature.

    • In combination with IBM Gigabit Ethernet Switches and the Interactive Network Dispatcher technology, IBM will deliver increased S/390 Server and Parallel Sysplex scalability.

    • With a 10X increase in bandwidth, Gigabit Ethernet enables customers to move data to and from their S/390 G5 Servers with ease, permitting aggregation of TCP/IP traffic, reducing the number of resources that must be managed, and facilitating network growth.
  • Non-disruptive replacement of I/O: In 1999, IBM intends to provide the capability to remove parallel and ESCON channels and replace them with higher bandwidth I/O attachment in a non-disruptive manner. An Initial Machine Load (IML) or a re-Initial Program Load (IPL) will not be required when replacing Parallel or ESCON channels.

  • Increased Memory for Future Servers: In 1999, IBM intends to provide up to 32 GB of memory on its servers.

  • TPF RECORD LEVEL LOCKING in the Coupling Facility: IBM intends to add to the 9674 Coupling Facility models C04, C05 and the 9672 model R06, and to Internal Coupling Facilities (ICF), and to the Coupling Facility Control Code (CFCC), to allow TPF 4.1 customers the capability for record level locking. This enhancement will provide an option to traditional locking mechanisms within DASD control units.

  • FICON control units and FICON director IBM intends to provide direct connect FICON directior and storage control units.

  • DB2 Coupling Facility Cache Duplexing for Group Buffer Pools IBM intends to provide this key availability enhancement for the DB2 datasharing environment, eliminating the need to perform lengthy recovery from DB2 logs in the event of a CF failure containing the DB2 cache structures.

  • Migration from 9674 Model C02 Coupling Facilities IBM intends to offer migration assistance from 9674 C02 and C03, as well as C04 and C05 Coupling Facilities to the new 9672 Generation 5 R06 Coupling Facility. This technology refresh will aid customers running Parallel Sysplex configurations who desire to exploit the enhancements to Parallel Sysplex offered with G5.

For a complete list of the supported I/O for the G5 models, refer to the 9672 Sales Manuals.



Hardware Management Console (HMC)

The Hardware Management Console provides a single point of control and single system image for managing local or remote hardware elements for the 9672 systems. The Hardware Management Console(s) communicate with the 9672 system(s) using either an SNA protocol or TCP/IP protocol flowing over either a Token-Ring LAN or over an Ethernet LAN. The Hardware Management Console employs a state-of-the-art direct-manipulation object-oriented graphical user interface supporting exception based real-time system status reporting via ICONs and colors, consolidated hardware messages, consolidated operating system messages, and consolidated service support (including modems and phone lines), and of course, full operation of the managed systems.

The Hardware Management Consoles ordered with a new S/390 G5 Server will be shipped as feature code #0041. All MES orders will include either replacement of the existing Hardware Management Console by #0041 or an upgrade to #0031, depending upon the level of system in the existing Hardware Management Console. HONE AID (CFSYSTEM) will determine the appropriate shipment content. When upgrading a system which has #0009 installed, that Hardware Management Console will be upgraded to either a #0031 or #0041, depending upon the type of PC in the existing Hardware Management Console (PS/2 (R) based #0009 will be exchanged for #0041; Model 6885 based #0009 will be upgraded to #0031). All upgrades from 9672 G3, 9674 C04 or earlier models, presently using #0021 should confirm order of FC #0031, as a no-charge feature. All upgrades from 9672 R3 as well as 9674 C03 models presently using #0009 should confirm feature exchange for either #0031 or #0041, depending upon the type of PC in the existing Hardware Management Console, as a no-charge feature exchange. #0041 is also available as an optional feature for customers who desire additional Hardware Management Console performance and flexibility, especially in multi-system environments. No upgrade path from #0031 to #0041 is available; #0031 and #0041 are fully compatible and may coexist on the same LAN. #0023 only be ordered if the #0041 Hardware Management Console will be connected to a Token-Ring LAN.

Technical differences between #0031 and #0041 are as follows:

  • #0031 includes the HMC Token-Ring support and HMC 3270 Emulation support, as standard function.

  • #0041 includes the HMC Ethernet support as standard function. HMC Token-Ring support is optional as #0023; HMC 3270 emulation support is optional as #0026. #0041 allows (2) of (3) options to be installed as follows:
    • HMC/SE ISDN (Integrated Services Digital Network) Feature (#0022)

    • HMC/Standalone SE Token Ring Feature (#0023)

    • HMC/Standalone SE 3270 Emulation Feature (#0026)
9672 or 9674 installations require at least one (1) local token-ring attached HMC for LIC updates (either #0031 or #0041) at this time; the HMC code senses installation of the token-ring hardware and assumes that token-ring is the protocol to be used.

Support Element: The G5 server models contain an integrated Support Element (SE) which provides distributed hardware operations and management. The SE controls and monitors the operation of the 9672 and sends status, hardware messages, and operating system (console integration) messages to the Hardware Management Console(s) for consolidation and exception processing.

Remote Operations: The System/390 (R) Parallel Enterprise Server and Coupling Facility hardware systems management products support remote operations in a variety of ways over a variety of communications connections. In each case, the objective is to enable a human or programmed operator to monitor or control a remote system in essentially the same manner as if the operator were at the same site as the remote system. Remote operations include:

  • Hardware Management Console Operation of S/390 Parallel Enterprise Server -- Generation 5, using:
    • An SNA protocol flowing over either a Token-Ring or Ethernet LAN, or

    • A TCP/IP protocol flowing over either a Token-Ring or Ethernet LAN.
    The systems connected by these LANs may be distributed over any geographic extent supported by interconnected LANs. This provides ideal support for consolidating the operation of remote data centers using existing networks. This is the suggested option for continuous remote operation of S/390 Parallel Enterprise Server -- Generation 5 systems.

  • Remote manual operation of a Hardware Management Console: The Hardware Management Console may be remotely operated over SDLC, Token-Ring, or Ethernet connections using either SNA or TCP/IP protocols, by utilizing the target portion of the integrated Distributed Console Access Facility (DCAF) product. To use this option, a personal computer is required with OS/2 (R), Communications Manager/2 (CM/2) or TCP/IP support, and the controller portion of the DCAF product. note that the DCAF product can no longer be ordered and is no longer supported, but existing DCAF controllers can still be used.

  • Remote Web browser operation of the Hardware Management Console The Hardware Management Console may be remotely operated using a Web browser. For each of the systems being managed by the Hardware Management Console, the user can:
    • Monitor the status
    • Monitor and handle hardware messages
    • Monitor and handle (console integration) operating system messages
    • Perform the following tasks: Activate, Deactivate, Load, Reset Normal and Reset Clear, PSW Restart, System Activity, Change LPAR Controls, Configure Channel Path On/Off, and Reassign CHPIDs between LPAR partitions.
    To use this option, a personal computer or other system with a Web browser is required as well as TCP/IP connectivity from the Hardware Management Console to this system via either a Token-Ring or an Ethernet LAN. This is intended for occasional remote operation of the systems being managed by the HMC.

  • Remote operation of the 9672 G5 Servers from other platforms

    Several facilities and Application Programming Interfaces (APIs) are available to other management applications to allow for remote operations and monitoring. These APIs support TCP/IP and SNA based remote management applications which may be provided by IBM, other software vendors, or the enterprise.

  • Hardware Management Console SNMP based Management

    The Hardware Management Console provides a system management set of APIs by means of the TCP/IP SNMP protocol.

  • Support Element SNMP based Management

    The Support Element provides a system management set of APIs by means of the TCP/IP SNMP protocol.

  • Support Element SNA based Management

    The Support Element provides a SNA based interface supporting SNA based management applications such as IBM NetView (R) and IBM TSCF.

RETAIN (R) support of Hardware Management Console-attached processors will be via SDLC links on the Hardware Management Console to an IBM RETAIN system.

HWMCA Programming Interfaces: In addition to providing an end-user with the ability to view and manipulate managed objects, the Hardware Management Console also provides APIs. The APIs are:

  1. User interface transitioning APIs
  2. Management APIs
The user interface transitioning API provides a local application with the ability to transfer into the Hardware Management Console user interface in context. This will be exploited by IBM's ESCON manager Release 3 product. The management APIs contain the ability to get/set a Hardware Management Console managed object's attributes, issue commands to be performed on a managed object from a local or remote application, and receive asynchronous event notifications. The management APIs provide a mechanism to IBM, independent system management vendors, and an enterprise, to integrate with the HWMCA.

Customization: The HMC can be tailored to the specific needs of each individual user. The variety of ways that the HMC can be customized include:

  • Security

    Access to the OS/2 desktop and other applications residing on the HMC can be limited for individual users.

  • Managed Objects

    Control of which managed objects, such as hardware elements, operating system images, and groups, that are accessible for individual users.

  • Tasks

    Control of which HMC tasks that are accessible for individual users.

The Coupling Facility can either be a 9674, a 9672 R06, an Internal Coupling Facility (ICF), or a coupling-capable server running Coupling Facility Control Code (CFCC). Two types of links have been in use on CMOS systems and must match at both the Coupling Facility (sender) end and the attached processor (receiver) end.

One HiPerLink adapter (#0216) is required for every two Coupling Links. The Intersystem Channel Adapter is not hot pluggable, but the Coupling Links are. Additional Intersystem Channel Adapters and Coupling Links can be ordered to reduce outages. Two types of Coupling Links are available on the G5 Models:

  • Coupling Link (#0007): Uses a multi-mode 50 micron fiber optic cable and has a full duplex connector that is Fibre Channel Standard (FCS) level 0 compliant. The link uses a short wave laser light source and can support distances of up to 1 kilometer between the Coupling Facility and attached systems. Existing installations using #0007 need to be advised of the following phase-out of multi-mode fiber optic: #0007 is not orderable with new build G5 orders: If an installation requires coupling between a G5 model, and existing multimode fiber (MMF) coupling links (#0007), contact your IBM Representative.

  • Coupling Link (#0008): Uses a 9 micron single-mode fiber optic cable and has a full duplex connector that is Fibre Channel Standard (FCS) level 0 compliant. This link uses a long wave laser light source and can support distances of up to 10 kilometers, and up to 20 km using an optional RPQ.
One standard length IBM fiber optic jumper cable will be provided at no additional charge for the connection between two Coupling Link features. Refer to the 9672 Sales Manual pages for jumper cable ordering information.

IBM's Fiber Transport Services (FTS)

IBM's Global Services FTS-III Direct Attach fiber optic trunk offering is now available for the 9672 G5 Models.

FTS-III Direct Attach fiber optic trunk cables support ESCON , Parallel Sysplex (R) and Open Systems Adapter-2 (OSA-2) fiber optic link connections. Direct Attach trunk cables allow trunk cable connections directly from a S/390 9672 processor, S/390 Coupling Facility 9674 and the 9032 ESCON Director Models 002, 003, and 005 into a main patch panel facility or directly to each other. Direct Attach trunk cables for the 9672 OSA fiber links allow trunk cable connections directly from the 9672 to a patch panel box located in the customer's wiring closet.

FTS-III Direct Attach fiber trunk cables and harnesses are the foundation for a highly organized, protected (eliminates the need for a fiber conveyance system), and easily movable fiber connectivity solution. By utilizing FTS-III structured cabling system, significant cost savings can be realized when relocating, reconfiguring, or adding additional hardware to the customer's ESCON, Parallel Sysplex and OSA installations.

The trunk cables are all plenum-rated OFNP (Optical Fiber Non-conductive Plenum) and are UL-910 approved. Charges are provided by Global Services on a per-contractual basis. Contact your Global Services representative for details. For more information, refer to Hardware Announcement 195-326 dated October 31, 1995, IBM Enhances Fiber Transport Services (FTS) and Services Announcement 696-025 dated September 10, 1996, Fiber Optic Trunk Cables for S/390 Processors and Coupling Facilities.

Fiber Quick Connect

IBM is now offering factory installation of direct-attach fiber optic trunking harnesses as an option with the G5 Servers. Direct-attach trunking eliminates the requirement for individual jumper cable connections to each ESCON or FICON channel, Coupling Link, HiPerlink, or Fast Ethernet, FDDI, or 155 ATM OSA-2 feature. Instead of up to 72 jumper cables exiting the server frame, one 72 channel trunk cable exits the G5 server. Fiber cable bulk is reduced both inside the server and under the raised floor.

With direct-attach trunking, individual channel ports can be quickly connected to a Main Distribution Facility (MDF) where the ports are arranged in patch panel boxes. Access to the I/O features in your S/390 G5 Server for configuration changes is no longer required. The server remains secure. Configuration changes are simplified and are made in one controlled area, the MDF, by authorized personnel moving short jumper cables between patch panels instead of moving long jumper cables under the raised floor. This reduces the scheduled outage times associated with moves, adds and changes.

IBM's structured fiber optic trunking system (Fiber Transport Services) utilizes the latest fiber optic technology to improve installation and configuration management. The Fiber Quick Connect feature enables the trunk harnesses to be installed at the factory so your server can be quickly connected to trunk cables pre-installed at your site. IBM's new MDF patch panels use the Small Form Factor (SFF) fiber optic connector called the DC (Dual Connection). This smaller sized duplex connector reduces the required MDF floor space by 50% when compared to current duplex connectors. The DC patch panels also enable your server CHPIDs to be arranged in sequential order with their CHPID addresses factory-labeled. Two DC patch panels support up to 256 CHPID addresses, so planning for future growth is made easy as well.

When the Fiber Quick Connect feature is selected for factory installation, the G5 server will arrive on site with the direct-attach trunk harnesses already installed. The trunks and patch panels can be installed prior to the arrival of the G5 Server and with the factory installation of the direct-attach harnesses, the on-site server install time can be reduced by up to 80%. As part of the factory installation package, documentation will be provided showing the CHPID layout and how the direct-attach harnesses are plugged.

IBM Global Services can provide the direct-attach trunk cables, patch panels, MDF hardware and planning and installation required to complete this total structured connectivity solution.

Installability: The new G5 servers have approximate installation times of 4.0 to 11.0 hours. Actual customer impact, actual downtime to existing systems, will vary depending upon installation scenario and configuration.

The field model upgrade time range, system downtime, is 2 to 8 hours, depending on the upgrade. These times assume that the prerequisite ECs and MESs have been installed prior to model upgrade.

Field upgrades require different lengths of time depending upon the customer configuration, the amount of work that can be accomplished in parallel at the customer location, and the method used to do the upgrade.

Security, Auditability, and Control



Reliability, Availability, and Serviceability

S/390 G5 Servers reduce downtime by using standard features that provide high levels of reliability, availability, and serviceability (RAS).



Reliability

The standard features that provide a high level of reliability include:

  • High-reliability technology components.

  • Parts integration to reduce the number of parts in the machine.



Availability

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

  • Enhanced Processor Design

    All S/390 G5 Servers are provided with an enhanced processor design. Each Central Processor contains dual Instruction/Execution Units, which operate simultaneously. Results are compared, and in the event of a miscompare, Instruction Retry is invoked. This design simplifies checking, and virtually eliminates CP failures due to soft errors.

  • Fault Tolerant Design

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

  • Processor Unit (PU) Sparing

    Spare Processor Units (PUs) are provided, whenever the configuration allows, to maintain performance levels should an active central processor (CP), Integrated Coupling Facility (ICF) feature or System Assist Processor (SAP) fail on a G3, G4 or G5 Server models. The general philosophy is to provide a spare chip whenever possible; that is, when the number of CPs, ICFs and SAPs is less than the total number of processing units (PUs) available.

    • Transparent CP/ICF Sparing

      New on the S/390 G5 Servers is Transparent CP/ICF Sparing. When originally announced on the G3 models, CP sparing (ICF feature not available at G3 announce) required an IML of the machine to activate the spare CP. Later on the G3 models and on the G4 models, Concurrent CP/ICF Sparing was introduced. With Concurrent CP/ICF Sparing, an IML is not required to activate a spare PU. In shared LPAR mode, Concurrent CP/ICF Sparing is automatic and does not required operator intervention; however, in Basic Mode or with LPAR dedicated partitions, operator action is required to bring the new CP/ICF on-line (Operating System must support configuring the spare CP on-line). With the G5 Servers, CP/ICF Sparing is transparent in all modes of operation and requires no operator intervention to invoke a spare CP. Because there are no extra chips available on the RX6 and YX6, these models do not support CP Sparing. The R06 model supports sparing for all ICF features (including the model configured with 10 ICF features).

      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. See Enhanced Application Preservation below.

    • Dynamic SAP Sparing/Reassignment

      Dynamic recovery is provided for failure of the System Assist Processor (SAP). In the event of a SAP failure, if a spare Processor Unit (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 Central Processor (CP), an active CP will be reassigned as a SAP. In either case, there is no customer intervention required. This capability eliminates an unplanned outage and permits a service action, if necessary, to be deferred to a more convenient time.

  • Enhanced Application Preservation

    Application Preservation was introduced on the G4 Servers and is enhanced on the G5 models to provide more comprehensive application recovery should a CP fail. 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 customer intervention. On the G3 and G4 models, the uniprocessors were not covered by Application Preservation; G5 uniprocessor models will now recover work due to a CP failure, in most cases, on a spare PU using Application Preservation. The RX6 and YX6, although without CP Sparing, will attempt to recover an application that was running on a failed CP on another active CP in the configuration. This capability helps eliminate unplanned outages, eliminates customer intervention in the recovery process, and preserves the customer's application processing environment.

  • Cryptographic Coprocessor Enhancements

    There are two Cryptographic Coprocesor Elements available in the G3, G4 and G5 Servers. On the G5 models, the availability has been enhanced by making both elements available on 2-way models and above. On G3 and G4 models, two cryptographic elements are available on the 5-way models and above with the 1-way through 4-way models having only a single cryptographic element. Recovery of a cryptographic coprocessor element is done by the operating system; i.e., the operating system reschedules and dispatches the failed instruction on the other cryptographic coprocessor element.

    Another new availability feature on the G5 Servers is a second path from each cryptographic coprocessor element to a spare PU. Normally, each crypto element is configured to a primary CP. Should a primary CP fail, the alternate PU would transparently replace (spare) the failed primary CP, maintaining the crypto element's operation. However, an alternate PU is available only if that PU is not configured into the system as another CP, ICF or SAP. The two PUs associated with the alternate path from each crypto element are the last to be assigned as CPs, SAPS or ICFs. It should be noted that if a primary CP is not available at IML, the cryptographic element will be configured with its associated alternate PU.

  • Dynamic ICF Expansion

    Dynamic ICF Expansion is a function that allows an ICF logical partition to acquire additional processing power from the LPAR pool of shared general purpose central processors being used to execute production and/or test work on the system. This function is very useful when the ICF partition in some G5 general purpose models backs up another Coupling Facility. In this event, the ICF, using Dynamic ICF Expansion, can acquire additional processing capacity to handle the full Coupling Facility workload. Also, Dynamic ICF Expansion can be used to handle a peak workload situation when the ICF is being used as the regular coupling facility. This feature adds considerable flexibility to the configurability of the ICF in G5 general purpose models and optimizes the use of the processing power in the system.

    The Dynamic ICF Expansion feature is available to every ICF Coupling Facility partition using coupling facility links. 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 not recommended for use in a logical coupling facility that uses ICMF.

    Dynamic ICF Expansion is available on G5 general purpose models RA6, R16, RB6, R26, RC6, R36, R46, R56, R66, R76, and R86.

  • Dynamic Coupling Facility Dispatching

    The Dynamic Coupling Facility (CF) Dispatching function helps enable continuous computing in the event of a coupling facility failure without requiring a standalone backup coupling facility. Enhanced dispatching algorithms enable you to define a backup coupling facility 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 detects and corrects single bit errors. Also, because of the memory structure design, errors due to a single memory chip failure are corrected.

  • Dynamic Memory Sparing

    Memory cards 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 Error Correction Code (ECC). Before a failure threshold is reached which could result in an uncorrectable error, 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 the memory card.

  • LPAR Dynamic Storage Reconfiguration (DSR) (on G5 general purpose models)

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

  • Enhanced LPAR Dynamic Storage Reconfiguration

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

  • Subsystem Storage Protect

    Subsystem storage protection and subspace group facility support, for use with CICS/ESA (R), prevents 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.

  • Partial Memory Restart

    In the event of a memory card failure, the system can be restarted with half of the original memory. Processing can be resumed until a replacement memory card is installed.

  • 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

    It is possible to concurrently add ESCON, Parallel and OSA channels and Coupling Facility (CF) Links provided an STI is installed and there are unused channel positions and a channel adapter card (for channels)/HiPerLink adapter card available. This capability may help eliminate an outage to upgrade the channel configuration.

  • Partial I/O Restart

    In the event of a failure of a Memory Bus Adapter, in most cases, the system will continue to run with only the I/O connections associated with the failed MBA deconfigured. In a system configured for maximum availability, alternate paths will maintain access to critical I/O. This capability enables the system to run, partially degraded, until the part is replaced, restoring full capacity.

  • 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. Customers may elect to provide a dual electrical service to the server, further minimizing 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 power thermal component does not cause a system outage.

  • Storage Recovery

    S/390 G5 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. S/390 G5 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 connection provided across clusters to enable the cluster degrade capability. The design includes both the full- and half- populated module cases.

  • Concurrent Hardware Maintenance

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

    • Power/Thermal
    • ESCON channels
    • FICON channels
    • Parallel channels
    • Coupling links
    • Integrated cluster bus (STI) cable
    • OSA2
    • Hardware Management Console
    • Support Element
  • Concurrent Licensed Internal Code (LIC) 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
    • Integrated Coupling Migration Facility
    • Power/Thermal
    • ESCON channels
    • FICON channels
    • Parallel channels
    • Coupling links
    • Integrated cluster bus channels
    • Internal coupling channels
    • OSA2
    • Hardware Management Console
    • Support Element
    Note: Not all patches are non-disruptive. Some patches still require a Power On Reset to be activated.
The optional features that provide a high level of availability include:
  • Internal Battery Feature (IBF)

    The Integrated Battery Feature (IBF) provides backup input power. The feature is packaged internal to the machine. It can be used with a UPS to provide additional protection.

  • Local Uninterruptible Power Supply

    The Local Uninterruptible Power Supply, Machine Type 9910, can be installed as a supplemental or as an alternative to a central UPS to secure system availability.

  • Redundant Coupling Links

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



Serviceability

The standard features that 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
The customer is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communications facilities.
