The IBM Systemz9 109 (z9-109) (announced July 2005), provided a strong combination of mainframe characteristics, plus newfunctions designed around scalability, availability, security, and virtualization. With the announcement in Mayof 2006, the z9-109 became known as the IBM System z9 Enterprise Class (z9 EC).With a modular book design, the z9 EC Model S54 is designed to provide up to 95% more total system capacitythan the z990 Model D32, and has up to double the available memory. The Modified Indirect Data AddressWord (MIDAW) facility is designed to improve FICON performance. The number of FICON Express2 openexchanges (concurrent I/O operations) that may be active simultaneously has been increased from 32 to 64per channel.The z9 is focused on providing higher availability and reducing planned and unplanned outages -- which, whenproperly configured, may be accomplished with improved nondisruptive replace, repair, and upgrade functionsfor memory, books, and I/O as well as extending nondisruptive capability to download Licensed Internal Codeupdates.Integrated clear key encryption security-rich features on the z9 include support for Advanced EncryptionStandard, Secure Hash Algorithm-256, and integrated Pseudo Random Number Generation. Performing thesefunctions in hardware is designed to contribute to improved performance.Innovations on the z9 can help to ensure you have a security-rich platform, can help maximize your resourcesand their utilization, and can help provide you the ability to integrate applications and data across theinfrastructure. The z9 is designed to be a flagship component of your heterogeneous environment.The z9 continues the evolution of the mainframe, building upon the structure introduced on z990 in support ofz/Architecture, reliability, availability, scalability, and clustering. The z9 expands upon a key attribute of theplatform - availability - to help ensure you have a resilient infrastructure designed to satisfy the requirements
  7. 7. A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 7 of 82of On Demand Business. With the increased performance and total system capacity possible for the z9, youhave an opportunity to continue to consolidate diverse applications on a single platform.The z9 EC is designed to provide:• Five New Hardware Models - offering 1 to 54 configurable PUs. The first four models (S08, S18, S28and S38) have 12 PUs per book. The enhanced capacity Model S54, our largest mainframe server, offers 16PUs in each of its four books.• Faster Uni processor - a 35% increase in capacity performance over the z990 Model 2084-301, and theoverall server capacity will be 95% more on the S54 than the z990 Model 2084-332.• Up to 54 CPs - The Model S54 is an enhanced capacity model. You can customize the machine to be a 1 to54-way. On the standard models, the first book has 10 configurable PUs, with 12 PUs each in books 2, 3and 4. The S54 has 12 configurable PUs in the first per book, and 14 configurable ones in each remainingbook. Like the S38, the S54 can be ordered with a minimum of 16 GB of memory up to a maximum of 512 GB.• Up to 512 GB Memory - Memory has been doubled from what was offered on the z990 processor - for aserver maximum capacity up to 512 GB with a maximum of 128 GB per book.• CBU for IFL, ICF and zAAP - The z9 will be able to activate most PU types as part of CBU upgrades:IFLs, zAAPs, ICFs and CPs (zIIPs added with GA2). This is in contrast to the z890 and z990 servers thatwere, and continue to be, only able to activate CPs as CBU upgrades.• Separate PU Pool Management - New on the z9, all zAAP, zIIP, ICF and IFL processors will be managedas individual separate and distinct processor types/pools by PR/SM. On the z990 all the specialty engineswere contained in just one ‘specialty pool’.• Redundant I/O Interconnect - Redundant I/O interconnect will help maintain critical connections todevices during enhanced book availability as it provides connectivity to the server I/O resources using asecond path from a different book.• Enhanced Driver Maintenance - One of the greatest contributors to downtime during planned outages isLicensed Internal Code (LIC) updates performed in support of new features and functions. When properlyconfigured, the z9 is designed to support activating select new LIC level concurrently. Concurrentactivation is only supported at specific sync points.• Enhanced Book Availability - The z9 is designed to allow a single book, in a multibook server, to beconcurrently removed from the server and reinstalled during an upgrade or repair action.• Dynamic Oscillator Switchover - The z9 has two oscillator cards, a primary and a backup. In the event ofa failure of the primary oscillator card, the backup is designed to detect the failure, switch over, andprovide the clock signal to the server transparently. Previously, in the event of a failure of the activeoscillator, a server outage would occur, the subsequent Power On Reset would select the backup, and theserver would resume operation. Dynamic oscillator switchover is exclusive to the z9.• Server Time Protocol – (available since January 31, 2007) Is a new time synchronization feature, ServerTime Protocol (STP), which is designed to provide the capability for multiple System z9 and zSeries serversto maintain time synchronization with each other. STP is planned to be the follow-on to the Sysplex Timer(9037-002). The Sysplex Timer and STP are designed to allow events occurring in different System z9,zSeries, and S/390 servers to be properly sequenced in time. Note: IBM intends to withdraw the SysplexTimer Model 2 (9037-002) from marketing in 2006. For more information, refer to HardwareAnnouncement 105-241, dated July 26, 2005, (IBM System z9 109).STP is designed to:• Allow clock synchronization for z9 EC, z9 BC, z990, and z890 servers and CFs without requiring theSysplex Timer• Support a multisite timing network of up to 100 km (62 miles) over fiber optic cabling, thus allowing aParallel Sysplex to span these distances

(12 STIs x 2.0 Gigabytes per STI x 4 books = 96 versus 16 STIs x 2.7GB per STI x 4 books = 172.8 ... 172.8/96 = 80%)• MIDAW Facility - The Modified Indirect Data Address Word (MIDAW) facility is a new and separatefacility, offering an alternative for a channel program to be constructed. The new design can help toimprove performance for native FICON applications that use extended format datasets (including DB2 andVSAM) by helping to improve channel utilization, reduce channel overhead, and improve I/O response times.The MIDAW facility is supported on z/OS 1.6 and above.• Multiple Subchannel Sets (MSS) per LCSS – MSS provides a second set of subchannels for definingParallel Access Volume (PAV) aliases. This new function can help provide relief from the 64K device limitby allowing PAV aliases to be defined without making device numbe3rs unavailable for defining additionaldevices. For some of our largest customers this is designed to provide an I/O constraint benefit.• 63.75K Subchannels for Set-0 - addresses a maximum of 64K-1 subchannels in subchannel set 0 (zero).Previously 1024 (1K) of these subchannels were reserved for system use. IBM is making 768 of thesesubchannels available for customer use. This change increases the storage attachment capability of theSystem z9 - for example the IBM TotalStorage DS8000 Series can be defined to attach 63.75K unitaddresses - so with 63.75K in the host there is symmetry between the server and the storage subsystem.• Up to 336 FICON Express2 Channels - Providing the capability to populate the 28 I/O slots in one I/Ocage allows the z9 to have a maximum of 336 FICON channels installed.• N_Port Virtualization N_Port ID Virtualization (NPIV) allows a single Fibre Channel Protocol (FCP) porton Linux on System z9 to appear as multiple, distinct ports providing separate port identification andsecurity zoning within the fabric for each operating system image as if each operating system image had itsown unique physical port. NPIV is similar to the Multiple Image Facility (MIF) available on ESCON andFICON channels.• IPv6 Support for HiperSockets - HiperSockets now supports Internet Protocol Version 6 (IPv6) designedby the Internet Engineering Task Force (IETF) to replace Internet Protocol Version 4 (IPv4) to helpsatisfy the demand for additional IP addresses. IPv6 provides more unique IP addresses by expanding theIP address space from 32 bits to 128 bits. IPv6 requires z/OS 1.6 and z/VM 5.2.• OSA-Express2 1000BASE-T - With the additional memory available on OSA-Express2, the 1000BASE-TEthernet feature will be able to: Support large send (offloading TCP segmentation processing from hostTCP/IP stack to OSA-Express2), 640 TCP/IP stacks for improved virtualization by hosting of more imageson System z9 and potentially reducing the number of required OSA features, and support of concurrentLIC update to minimize network traffic disruption.• OSA-Express2 OSN (OSA for NCP) - The OSA-Express2 OSN (OSA for NCP) is designed to providesupport for the IBM Communication Controller for Linux (CCL) on System z V1.2.1. OSA for NCP will helpto eliminate dependencies on hardware such as the 3745/6. It helps to collapse SNA within the serverwhile exploiting and leveraging IP.

PRNG is a standardfunction supported on the Crypto Express2 feature. CPACF, supporting clear key encryption, is standard onevery CP and IFL; however a no charge enablement feature #3863 is required.• Configurable Crypto Express2 – The Crypto Express2 feature has two PCI-X adapters, and each can bedefined as either a coprocessor or as an accelerator. The Crypto Express2 feature with both PCI-Xadapters defined as accelerators is designed to perform up to 6000 SSL handshakes per second. That is a3X performance improvement compared to the z990 when using either a PCI Cryptographic Accelerator(PCICA) feature, with two PCI accelerators per feature, or the current Crypto Express2 feature, with twoPCI coprocessors per feature.

Realizing the requirement for more granular capacity settings within the z9 EC,now offers you central processors with a larger variety of capacity choices that can help meet your businessrequirements. These processors will continue to have the ability to support all z9 EC features and functions.The mainframe has evolved our use of specialty engines over time starting with the Internal Coupling Facility(ICF). The latest specialty engine, announced in January of 2006, is the zIIP. The IBM zIIP is the latestcustomer-inspired specialty engine for the IBM System z9 family. The zIIP, when combined with an enablingWeb deliverable for z/OS V1.6 and V1.7 and enabling PTFs for DB2 UDB for z/OS V8, is designed to helpimprove resource utilization and lower the cost of eligible workloads, enhancing the role of the z9 EC as thedata hub of the enterprise.The z9 EC now includes FICON Express4 for potential improved I/O capacity and performance with the nextgeneration of FICON/FCP. This new feature may offer increased channel aggregation and shorter backupwindows to help reduce the cost of storage operations and infrastructure. IBM has a broad range of disk, tape,and SAN products that are ready to support FICON Express4. With these enhanced capabilities, the z9 EC isintended to help increase the flexibility to configure a server to meet current needs, provide a powerful andadvanced data serving environment, and help drive down risks and business costs. The z9 EC is designed tooptimize your resources without sacrificing features or functions, both within the server and within theenterprise.

A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 11 of 82Additionally, the z9 EC includes support for Remote Key Loading for ATMs and point of sale devices, andimplementation of ISO 16609 CBC Mode TDES MAC.Remote Key Loading refers to the process of loading Data Encryption Standard (DES) keys to AutomatedTeller Machines (ATMs) and Point of Sale (POS) devices from a central administrative site without the needfor personnel to visit each machine to manually load DES keys. These enhancements provide two important newfeatures: the ability to load initial keys to an ATM or a POS device from a remote location, and enhancedcapabilities for exchanging keys with non-CCA cryptographic systems.Remote Loading of Initial ATM Keys: Typically, a new ATM has none of the financial institutions keysinstalled. Remote Key Loading refers to the process of loading Data Encryption Standard (DES) keys toAutomated Teller Machines (ATMs) from a central administrative site without the need for personnel to visiteach machine to manually load DES keys. This has been done by manually loading each of the two clear text keyparts individually and separately into ATMs. Manual entry of keys is one of the most error-prone and labor-intensive activities that occur during an installation, making it expensive for the banks and financial institutions.Remote Key Loading Benefits: • Provides a mechanism to load initial ATM keys without the need to sendtechnical staff to ATMs.• Reduces downtime due to key entry errors.• Reduces service call and key management costs.• Improves the ability to manage ATM conversions and upgrades.Integrated Cryptographic Service Facility (ICSF), together with Crypto Express2, support the basicmechanisms in Remote Key Loading. The implementation offers a secure bridge between the highly secureCommon Cryptographic Architecture (CCA) environment and the various formats and encryption schemesoffered by the ATM vendors. The following are new ICSF services are offered for Remote Key loading:• Trusted Block Create (CSNDTBC) - This callable service is used to create a trusted block containing apublic key and some processing rules. The rules define the ways and formats in which keys aregenerated and exported.• Remote Key Export (CSNDRKX) - This callable service uses the trusted block to generate or exportDES keys for local use and for distribution to an ATM or other remote device.Refer to Application Programmers Guide, SA22-7522, for additional details.Improved Key Exchange With Non-CCA Cryptographic Systems: IBM Common Cryptographic Architecture(CCA) employs Control Vectors to control usage of cryptographic keys. Non-CCA systems use other mechanisms,or may use keys that have no associated control information. This enhancement provides the ability toexchange keys between CCA systems, and systems that do not use Control Vectors. Additionally, it allows theCCA system owner to define permitted types of key import and export which can help to prevent uncontrolledkey exchange that can open the system to an increased threat of attack.ISO 16609 CBC Mode T-DES Enhancement: ISO 16609 CBC Mode T-DES MAC supports the requirementsfor Message Authentication, using symmetric techniques. ICSF will use the following callable services to accessthe ISO 16609 CBC Mode T-DES MAC enhancement in the Cryptographic coprocessor:• MAC Generate (CSNBMGN)• MAC Verify (CSNVMVR)• Digital Signature Verify (CSNDDSV)ISO 16609 CBC mode T-DES MAC is accessible through ICSF function calls made in the Cryptographic AdapterSegment 3 Common Cryptographic Architecture (CCA) code.

This new generationof IBM mainframes provides an advanced combination of reliability, availability, security, scalability, andvirtualization features, together with the ability to reallocate processing power. The z9 BC is designed tomatch changing business priorities on demand.The z9 BC is designed specifically as a midrange mainframe and offers extensive growth options and excellentprice/performance for those customers requiring a lower-capacity entry point and more granular growthoptions than offered with the z9 EC.The IBM z9 BC is designed to help enable your businesses to be resilient in the unpredictable on demand world.With two models and a wide range of capacity settings, the newest member of the IBM System z9 familydelivers significantly improved granularity and enriched functions over its predecessor, the IBM eServerzSeries z890. The Model S07 can provide up to twice the memory, and more specialty engines as compared withthe z890. Also introduced is the new System z9 Integrated Information Processor (zIIP).The z9 BC offers four new FICON Express4 features that support auto-negotiated speeds of 1, 2, and 4 Gbps.One of the FICON Express4 features is a 2-port card that provides attractive entry pricing to FICONtechnology adoption and is offered exclusively on the z9 BC.All FICON Express4 and FICON Express2 features support the Modified Indirect Data Address Word(MIDAW) facility. MIDAW is a new system architecture with software exploitation that is designed to helpimprove channel utilization and throughput, and potentially reduce I/O response times. The number of FICONExpress4 and FICON Express2 concurrent I/O operations that may be active simultaneously has beenincreased from 32 to 64 per channel as compared to the z890.IBM has a broad range of disk, tape, and SAN products that are ready to support FICON Express4.

The servers andCoupling Facilities that are capable of supporting Server Time Protocol are:• IBM System z9 Enterprise Class (z9 EC)• IBM System z9 Business Class (z9 BC)• IBM eServer zSeries 990• IBM eServer zSeries 890Server Time Protocol is a server-wide facility that is implemented in the Licensed Internal Code (LIC) of z9EC, z9 BC, z990, z890, and CFs and presents a single view of time to Processor Resource/Systems Manager(PR/SM). STP uses a message-based protocol in which timekeeping information is passed over externallydefined Coupling Links - InterSystem Channel-3 (ISC-3) links configured in peer mode, Integrated Cluster Bus-3 (ICB-3) links, and Integrated Cluster Bus-4 (ICB-4) links. These can be the same links that already are beingused in a Parallel Sysplex for Coupling Facility (CF) message communication.By using the same links to exchange timekeeping information and Coupling Facility messages in a ParallelSysplex, STP can scale with distance. Servers exchanging messages over short distance links such as ICB-3 andICB-4 are designed to meet more stringent synchronization requirements than servers exchanging messagesover long distance links such as ISC-3 (distances up to 100 km), where the synchronization requirements areless stringent. This is an enhancement over the current Sysplex Timer implementation, which does not scalewith distance.The STP design has introduced a new concept called Coordinated Timing Network (CTN). A Coordinated TimingNetwork (CTN) is a collection of servers and Coupling Facilities that are time synchronized to a time valuecalled Coordinated Server Time.STP supports the following functions:
  15. 15. A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 15 of 82• Initialize the time manually or by dialing out to a time service, so that Coordinated Server Time can beset to within 100 milliseconds of an international time standard such as Coordinated Universal Time(UTC).• Schedule periodic dial-outs to a time service so that Coordinated Server Time may be gradually steeredto an international time standard.• Initialize Time Zone offset, Daylight Saving Time (DST) offset, Leap seconds offset.• Schedule changes to offsets listed above. STP can automatically schedule Daylight Saving Time, basedon the selected Time Zone, a capability that did not exist on the Sysplex Timer.• Adjust Coordinated Server Time by up to +/- 60 seconds. This improves upon the Sysplex Timerscapability of adjusting time by up to +/- 4.999 seconds.STP EnhancementsThe Server Timer Protocol feature is designed to simplify hardware configurations by:• Allowing clock synchronization for z9 EC, z9 BC, z990, and z890 servers and Coupling Facilities withoutrequiring the Sysplex Timer and dedicated timer links. This helps reduce the need for separatehardware that needs to be ordered and maintained.• Supporting a multisite timing network of up to 100 km (62 miles) over fiber optic cabling, thus allowing asysplex to span these distances. This overcomes the limitations of the Sysplex Timer to Sysplex Timerlinks being supported only up to 40 km. STP is designed to eliminate the need for a third site to locatethe second Sysplex Timer for installations where the multisite sysplex spans a distance greater than40 km but less than 100 km (the current limit for Sysplex Timer to server connection).• Potentially reducing the cross-site connectivity required for a multisite Parallel Sysplex. Dedicatedlinks are no longer required to transport timing information since STP and Coupling Facility messagesmay be transmitted over the same links.Additional value from Server Time Protocol may be obtained by:• Eliminating infrastructure requirements (space, power, etc) needed to support Sysplex Timers• Eliminating Sysplex Timer maintenance costs• Eliminating fiber optic infrastructure requirements for:o Patch/trunk cableso Dense Wavelength Division Multiplexer (DWDM) portso Dark fiber between sites for External Time Reference (ETR) and Control Link Oscillator (CLO)links (links between Sysplex Timers)Concurrent Migration and CoexistenceSTP introduces the concept of a Coordinated Timing Network (CTN), to meet two key goals of System zcustomers:• Concurrent migration from an existing External Time Reference (ETR) network to a timing networkusing STP.• Capability of servers that cannot support STP to be synchronized in the same network as servers thatsupport STP (z9 EC, z9 BC, z990, z890)A CTN can be configured in two ways:• Mixed CTN (ETR and STP) which requires a Sysplex Timer. The Sysplex Timer provides thetimekeeping information in a Mixed CTN.A Mixed CTN allows you to meet the above requirements of concurrent migration and coexistence. Thecoexistence allows for a sysplex configuration where members of the sysplex may reside on a z800 or z900server.• STP-only CTN which does not require a Sysplex Timer.

To help facilitate resolution, the operating system can now request the RNID datafor each device or control unit attached to native FICON channels and display the RNID data using an operatorcommand. In z/OS, the output of the DISPLAY MATRIX operator command (D M=DEV) includes RNIDs to helpmake it easier to diagnose these problems by making additional information, such as a devices serial number,available.RNID is exclusive to the z9, and is supported by the FICON Express2 and FICON Express features (CHPIDtype FC), and by z/OS.Up to 60 Logical Partitions: IBM is once again doubling the number of Logical Partitions (LPARs). You now havethe ability to define up to 60 LPARs, 15 LPARs per Logical Channel Subsystem, which may provide you evenmore flexibility to allocate hardware resources. With Processor Resource/Systems Manager (PR/SM) andMultiple Image Facility (MIF) you can share ESCON and FICON channels, ISC-3s, and OSA ports across LPARs.Support for up to 30 LPARs became available October 2003.Support of up to 60 LPARs is exclusive to the z9 EC server and is supported by z/OS, z/VM, z/VSE (TM), TPF,z/TPF, and Linux on System z9.OSA-Express2 OSN - Open Systems Adapter for NCP: The OSA-Express2 Gigabit Ethernet and1000BASE-T Ethernet features (#3364, #3365, #3366) now have the capability to provide channelconnectivity from System z9 operating systems to IBM Communication Controller for Linux on zSeries (CCL)with the introduction of the Open Systems Adapter for the Network Control Program (OSA for NCP)supporting the Channel Data Link Control (CDLC) protocol, providing an alternative to a SNA network.
  27. 27. A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 27 of 82OSA-Express2 OSN can help to eliminate the requirement to have any form of external medium (and allrelated hardware) for communications between the host operating system and the CCL image. Traffic betweenthe two images (operating system and CCL) is no longer required to flow on an external Local Area Network(LAN) or ESCON channel; traffic can flow LPAR-to-LPAR. OSA-Express2 OSN provides an efficient method ofcommunication, and is designed to create a secure and seamless integration of the host operating system andCCL.If you continue to require SNA solutions that require NCP functions, you can now consider CCL as a migrationstrategy to replace your IBM Communications Controllers (374x). The CDLC connectivity option enables TPFenvironments to now exploit CCL.The OSA-Express2 Gigabit Ethernet and 1000BASE-T Ethernet features provide connectivity with a newCHPID type OSN (Open Systems Adapter for NCP). Each host operating system that currently supports CDLCis expected to be able to utilize CDLC to CCL without changes to the operating system. OSA-Express2 OSNsupports both SNA PU Type 5 and PU Type 2.1 channel connectivity.Utilizing existing SNA support (multiple transmission groups), OSA-Express2 OSN support permits multipleconnections between the same CCL image and the same host operating system (such as z/OS or TPF) image.The operating systems must reside within the same physical server (CPC) as the CCL image.OSA-Express2 OSN:• Is designed to appear to the operating systems as an ESCON channel connected to a 374x device typewhich exploits existing CDLC protocols• Allows system administrators of the various operating systems to configure, manage, and operate theirCCL NCPs as if they were running in an ESCON-attached 374x Communications Controller• Enables NCP channel-related functions such as loading and dumping of the NCP• Does not require external hardware (cables or switches)• Allows multiple CCL images to communicate with multiple operating system images, supporting up to 180connections (374x subchannels) per CHPID type OSN• Can span Logical Channel SubsystemsThe CCL image connects to OSA-Express2 OSN using extensions to the QDIO architecture. Linux support is inthe QETH module.OSA-Express2 OSN support is exclusive to the z9, to the OSA-Express2 Gigabit Ethernet SX, GigabitEthernet LX, and 1000BASE-T Ethernet features (#3364, #3365, #3366), and requires the port to beconfigured as CHPID type OSN, which can be configured on a port-by-port basis. OSA-Express2 OSN isexclusively for internal communication, LPAR-to-LPAR. Concurrent LIC update is supported. OSA-Express2OSN is supported by z/OS, z/VM, z/VSE, TPF, and Linux on System z9. Refer to the Software requirementssection. Refer to the Statement of General Direction section for information on IBM Communication Controllerfor Linux on zSeries support of OSA-Express2 OSN.Improved FICON error recovery: System z9 and z/OS and z/OS.e V1.7 I/O recovery processingimprovements are designed to allow for the system to detect switch/director fabric problems that may causeFICON links to fail and recover multiple times in a short period of time.This enhancement is designed to allow the system to detect these conditions and keep an affected path offlineuntil an operator action is taken. This is expected to help limit the performance impacts of switch/directorfabric problems. The improved FICON error recovery function is available on z/OS V1.4 with the z/OS V1.4z990 Exploitation Support feature (or z/OS.e V1.4 with the z/OS.e V1.4 z990 Coexistence Update feature)with PTFs.

The use of the MIDAW facility, by applications that currently use data chaining, may resultin improved FICON performance by reducing channel, director, and control unit overhead. Applications that usethe following may benefit: DB2, VSAM, Partitioned Data Set Extended (PDSE), Hierarchical File System (HFS),z/OS File System (zFS), and other datasets exploiting striping and compression. Specifically, MIDAWsexploitation by z/OS is expected to improve performance for some DB2 table scan, DB2 sequential prefetch,BSAM, and extended-format data set operations by reducing system overhead for I/O requests on the z9 ECor z9 BC server, with no application changes.The MIDAW facility is exclusive to the z9, and is supported by ESCON (CHPID type CNC), and by the FICONfeatures (CHPID types FCV and FC).Cryptographic support: Integrated Cryptographic Service Facility (ICSF) supports the cryptographicfunctional updates provided by the z9, including support for clear key AES and SHA-256 cryptographicalgorithms. These functions are designed to allow customers to exploit new high-capacity hardware and a morerobust development environment, in order to help grow existing applications and deploy new applications.Enhancements to CP Assist for Cryptographic Function (CPACF): CPACF, supporting clear key encryption, isactivated using a no-charge enablement feature (#3863) and offers the following on every Processor Unit (PU)identified as a Central Processor (CP) or Integrated Facility for Linux (IFL):• Data Encryption Standard (DES)• Triple Data Encryption Standard (TDES)• Secure Hash Algorithm (SHA-1)CPACF has been enhanced to include support of the following on CPs and IFLs:• Advanced Encryption Standard (AES) for 128-bit keys• Pseudo Random Number Generation (PRNG)• SHA-256PRNG is a standard function supported on the Crypto Express2 feature.CPACF performance is designed to scale with PU performance improvements. SHA-1 and SHA-256 are shippedenabled on all servers and do not require the enablement feature.Support for CPACF is also available using the Integrated Cryptographic Service Facility (ICSF). ICSF is acomponent of z/OS, and is designed to transparently use the available cryptographic functions, whether CPACFor Crypto Express2, to balance the workload and help address the bandwidth requirements of your applications.Configurable Crypto Express2: The Crypto Express2 feature has two PCI-X adapters. Each of the PCI-Xadapters can be defined as either a Coprocessor or an Accelerator.• Crypto Express2 Coprocessor - for secure key encrypted transactions (default)o Designed to support security-rich cryptographic functions, use of secure encrypted key values,and User Defined Extensions (UDX)o Designed for Federal Information Processing Standard (FIPS) 140-2 Level 4 certification• Crypto Express2 Accelerator (the acceleration mode for SSL/TLS operations and digital certificateoperations which were previously done in the PCICA card allows customers to migrate from PCICA tothe X Crypto Express2) - for Secure Sockets Layer (SSL/TLS) accelerationo Designed to support clear key RSA operationso Offloads compute-intensive RSA public-key and private-key cryptographic operations employedin the SSL protocolWhen a System z9 with four CPs and both PCI-X adapters on a Crypto Express2 feature are configured asaccelerators, the Crypto Express2 feature is designed to perform up to 6000 SSL handshakes per second. This

A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 32 of 82represents, approximately, a 3X performance improvement compared to z990 when using either a PCICryptographic Accelerator (PCICA) feature, with two PCI accelerators per feature, or the current CryptoExpress2 feature, with two PCI-X adapters per feature. The SSL performance was achieved using z/OS V1.7with Cryptographic Support for z/OS V1.6/V1.7 Web deliverable, and ICSF FMID HCR7730.Since the performance enhancements are implemented in Licensed Internal Code, current Crypto Express2features carried forward from z990 to System z9 may take advantage of increased SSL performance and thenew configuration capability.These measurements are examples of the maximum handshakes per second achieved in a laboratoryenvironment with no other processing occurring and do not represent actual field measurements. Details areavailable upon request.For z/OS V1.6, z/OS.e V1.6, z/OS V1.7 or z/OS.e V1.7: If you want to exploit either of the following:o Enhancements to CP Assist for Cryptographic Functions (CPACF) on the System z9 server. Theenhancements are support for the Advanced Encryption Standard (AES) for 128-bit keys, Secure HashAlgorithm-256(SHA-256), and Pseudo Random Number Generation PRNG.o Crypto Express2 exploitation when a Crypto Express2 PCI-X adapter is configured as an accelerator or acoprocessor on the System z9 serverthen you must download and install the Cryptographic Support for z/OS V1R6/R7 Web deliverable (which wasFMID HCR7730, or the follow-on Enhancements to Cryptographic Support for z/OS and z/OS.e V1R6/R7 Webdeliverable, which is FMID HCR7731), as well as the service identified in the program directory that comeswith the Web deliverable and the service which is recommended in the appropriate ICSF PSP bucket. Pleasenote that these Web deliverables also provides support for callers running in 64-bit addressing mode.For z/OS V1.6, z/OS.e V1.6, z/OS V1.7 or z/OS.e V1.7: If you will exploit Remote Key Loading forATMs and Point of Sale devices (POSs), or will implement ISO 16609 CBC Mode TDES MAC, then you mustdownload and install the Enhancements to Cryptographic Support for z/OS and z/OS.e V1R6/R7 Webdeliverable, which is FMID HCR7731, as well as the service identified in the program directory that comes withthe Web deliverable and the service which is recommended in the appropriate ICSF PSP bucket. Note that forz/OS and z/OS.e V1.8, which are planned to be available September 2006, the web deliverable is not needed.System z9 Integrated Information Processor (zIIP): The System z9 Integrated Information Processor(zIIP) is the latest specialty engine for the IBM System z9 mainframe. The zIIP is designed to help improveresource optimization and lower the cost of portions of eligible workloads, enhancing the role of the System z9mainframe as the data hub of the enterprise. The System z9 Integrated Information Processor (zIIP) will jointhe ranks of the eServer zSeries Application Assist Processor (zAAP), and Integrated Facility for Linux (IFL).All specialty engines run full speed.The zIIPs execution environment will accept eligible work from z/OS (minimum level is z/OS and z/OS.e V1.6),which will manage and direct the work between the general purpose processor and the zIIP. DB2 for z/OS V8will exploit the zIIP capability for portions of eligible workloads. The zIIP will be available on the System z9mainframe, and its introduction can help increase the value that customers may derive from the System z9mainframe over previous generations of the IBM mainframe.If you are running z/OS (or z/OS.e) V1.6 or V1.7 and want to use a new IBM System z9 IntegratedInformation Processor Support (zIIPs), then you must download and install the IBM System z9 IntegratedInformation Processor Support for z/OS and z/OS.e V1R6/R7 Web deliverable, which is FMID JBB77S9 for

Note that for z/OS and z/OS.e V1.8,which are planned to be available September 2006, the web deliverable and PTFs from the BCPZIIP PSP bucketare not needed. (zIIP PTFs will be included in the BCP subset for z/OS V1R8).There are updates to Omegamon products for zIIP support targeted for general availability. Refer to thezIIP PSP bucket for APAR information.1. OMEGAMON XE on z/OS2. OMEGAMON II for MVS v550 *3. OMEGAMON Base v550 (component of the above products)4. OMEGAMON XE for DB2 Performance Expert on z/OS v3105. OMEGAMON XE for DB2 Performance Monitor on z/OS v310* OMEGAMON II for MVS is a component product of OMEGAMON XE on z/OS, but also a product in its ownright. It also contains within it the product called OMEGAMON for MVS (which customers often refer to as"OMEGAMON Classic").You must also contact your vendors regarding zIIP support. The FMID for the web downloads changes thez/OS release to 1.7.1 for z/OS 1.7 and z/OS 1.6.1 for z/OS 1.6. Check with your ISVs to ensure this will notbe a problem.It is possible to estimate the potential amount of DRDA work which can be redirected to a zIIP prior toinstalling the required hardware and software. IBM has developed tools which can process RMF and DB2 datato provide this information. In order to do this analysis, please have your IBM account team make a request toIBM Techline for a zIIP estimation analysis. IBM Techline will provide a data collection guide as well as anoptional DB2 data reduction tool. The data collection guide asks several questions to allow IBM to do theproper evaluation. Return the completed data collection guide as well as FTP the required RMF data andoptional DB2 data created by the DB2 data reduction program to IBM. The data will be analyzed and a reportsent to your IBM account team.Once the proper level of software is installed on the customer machine, RMF and DB2PM will provide additionalinformation which will show the potential for redirecting work to a zIIP. By using the new PROJECTCPU optionin SYS1.PARMLIB member IEAOPTxx, this analysis can be done prior to installation of the actual zIIPhardware.Special note on TCP Segmentation Off-load feature (also called OSA Large Send): The TCP SegmentationOff-load feature is enabled by default if all of the requirements documented in PK02490 are met. Due to thepotential for OSAs that are using this feature to experience unrecoverable INOPs (requiring intervention byconfiguring the affected CHPIDs off-line), it is currently recommended that Segmentation Off-load bedisabled. To disable Segmentation Offload, it is recommended that the following maintenance be applied andthen code NOSEGMENTATIONOFFLoad on the GLOBALCONFIG statement in the TCPIP PROFILE. Once all ofthe microcode issues for Segmentation Offload are resolved, a Washington Systems Center Flash will bereleased advising what the minimum recommended code level will be. Flash 1232599 on the z/OSCommunications Server Support web page will also be updated at that time. Go to URLhttp://www.ibm.com/software/network/commserver/zos/support/ to subscribe to this (and other) updates.APAR/PTF updates were added to 2094DEVICE and 2096DEVICE PSP buckets in the R8, R7 and R6 sections todisable Segmentation Off-load (OSA Large Send.)

Two subchannel sets are now available per LCSS and are designed to enable a total of 63.75Ksubchannels in set-0 and the addition of 64K-1 subchannels in set-1.With the multiple subchannel set facility, one or two sets of subchannels may be configured to each LCSSwhere subchannel set 0 (zero) may have from 1 to 63.75K subchannels defined, and subchannel set 1 (one) mayhave from 1 to (64K-1) subchannels defined. z/OS will allow Parallel Access Volume Alias (PAV-alias) devices inthe subchannel set 1 (one). MSS is designed to provide greater I/O device configuration capabilities for largeenterprises.z/OS V1.7 supports the use of a second subchannel set for defining Parallel Access Volumes (PAV) aliases onthe z9 EC and z9 BC servers, which provides an additional 64K subchannels. Moving PAV alias definitions to asecond subchannel set can allow more devices to be defined. This new function provides relief from the 64Kdevice limit by allowing PAV aliases to be defined without making device numbers unavailable for definingadditional devices. EREP support is also provided to include the subchannel number for PAV alias devices.MSS is exclusive to the z9 EC and z9 BC servers, and is supported by ESCON (CHPID type CNC), by all of theFICON features supported on the z9 (CHPID type FC), by z/OS, z/OS.e, and Linux on System z9.Wild branch diagnosis improvement: A new hardware function stores the address of the last successfulbranch instruction on the z9. z/OS (and z/OS.e) V1.7 is designed to include this information in dumps, whichcan make it easier to find a program that branches to an unexpected location. This can help decrease problemdetermination time, improve the quality of failure diagnosis, and enhance the probability of first failure faultisolation.
