IBM System z Statements of Direction • The IBM z. Enterprise EC 12 will be the last high-end server to support connections to an STP Mixed CTN. This includes the Sysplex Timer® (9037). After z. EC 12, servers that require time synchronization, such as to support a base or Parallel Sysplex®, will require Server Time Protocol (STP), and all servers in that network must be configured in STP-only mode. • Removal of support for Ethernet half-duplex operation and 10 Mbps link data rate : The OSAExpress 4 S 1000 BASE-T Ethernet feature is planned to be the last copper Ethernet feature to support halfduplex operation and a 10 Mbps link data rate. The IBM z. Enterprise EC 12 servers are planned to be the last IBM System z servers to support half-duplex operation and a 10 Mbps link data rate for copper Ethernet environments. Any future 1000 BASE-T Ethernet feature will support full-duplex operation and autonegotiation to 100 or 1000 Mbps exclusively. • Removal of ISC-3 support on System z: The IBM z. Enterprise EC 12 is planned to be the last high-end System z server to offer support of the Inter. System Channel-3 (ISC-3) for Parallel Sysplex environments at extended distances. ISC-3 will not be supported on future high-end System z servers as carry forward on an upgrade. Previously we announced that the IBM z. Enterprise 196 (z 196) and IBM z. Enterprise 114 (z 114) servers were the last to offer ordering of ISC-3. Enterprises should continue migrating from ISC-3 features (FC 0217, FC 0218, FC 0219) to 12 x Infini. Band (FC 0171 - HCA 3 -O fanout) or 1 x Infini. Band (FC 0170 HCA 3 -O LR fanout) coupling links. • Removal of OSA-Express 3 support on System z: The IBM z. Enterprise EC 12 is planned to be the last high -end System z server to offer support of the Open System Adapter-Express 3 (OSA-Express 3 #3362, #3363, #3367, #3370, #3371) family of features. OSA-Express 3 will not be supported on future high-end System z servers as carry forward on an upgrade. Enterprises should continue migrating from the OSA-Express 3 features to the OSA-Express 4 S features (FC 0404, FC 0405, FC 0406, FC 0407, FC 0408).

IBM System z Statements of Direction … • Removal of support for connections to an STP Mixed CTN: The IBM z. Enterprise EC 12 will be the last highend server to support connections to an STP Mixed CTN. This includes the Sysplex Timer® (9037). After z. EC 12, servers that require time synchronization, such as to support a base or Parallel Sysplex®, will require Server Time Protocol (STP), and all servers in that network must be configured in STP-only mode. • Removal of Crypto Express 3 support on System z: The IBM z. Enterprise EC 12 is planned to be the last highend System z server to offer support of the Crypto Express 3 feature (FC 0864). Crypto Express 3 will not be supported on future high-end System z servers as carry forward on an upgrade. Enterprises should begin migrating from the Crypto Express 3 feature to the Crypto Express 4 S feature (FC 0865). • IBM Java exploitation of IBM z. Enterprise EC 12 functions: IBM plans for future maintenance roll-ups of IBM 31 -bit and 64 -bit SDK 7 for z/OS Java(TM) Technology Edition, Version 7 (5655 -W 43 and 5655 -W 44) (IBM SDK 7 for z/OS Java), to provide exploitation of new IBM z. Enterprise EC 12 features, including: Flash Express and pageable large pages, Transactional Execution Facility, Miscellaneous-Instruction-Extension Facility, and 2 GB pages. In addition, IBM SDK 7 for z/OS Java is available for use by IBM middleware products running Java, such as IBM IMS 12 (5635 -A 03), IBM DB 2 10 for z/OS (5605 -DB 2), and the Liberty profile of IBM Web. Sphere Application Server for z/OS v 8. 5 (5655 -W 65); and is planned for use by a future release of CICS Transaction Server for z/OS. • IBM System z Integrated Information Processor (z. IIP) and IBM System z Application Assist Processor (z. AAP) Simplification: IBM z. Enterprise EC 12 is planned to be the last high-end System z server to offer support for z. AAP specialty engine processors. IBM intends to continue support for running z. AAP workloads on z. IIP processors ("z. AAP on z. IIP"). This is intended to help simplify capacity planning and performance management, while still supporting all the currently eligible workloads. In addition, IBM plans to provide a PTF for APAR OA 38829 on z/OS V 1. 12 and V 1. 13 in September 2012 to remove the restriction that prevents z. AAP-eligible workloads from running on z. IIP processors when a z. AAP is installed on the server. This is intended only to help facilitate migration and testing of z. AAP workloads on z. IIP processors All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice.

IBM System z Statements of Direction … • IBM plans to provide new capability within the Tivoli Integrated Service Management family of products designed to leverage analytics information from IBM z. Aware, and to provide alert and event notification. • CPU Management for System x blades: IBM intends to deliver workload-aware optimization for IBM System x Blades in the z. BX. This allows virtual CPU capacity to be adjusted automatically across virtual servers within a hypervisor, helping to insure that System x resources in the z. BX are executing to the defined SLAs. • Automated Multi-site Recovery: IBM intends to deliver automated multi-site recovery for z. BX hardware components based upon GDPS technologies. These capabilities will help facilitate the management of planned and unplanned outages across IBM z. Enterprise EC 12. • IBM Systems Director Standard Edition for Linux on System z: IBM intends to deliver new functionality in IBM Systems Director Standard Edition for Linux on System z to support IBM's z. BX. Such planned new capabilities will be designed to provide virtual image management and enhanced energy management functions for the Power Systems and System x blades. • DB 2 continues to deliver extremely high availability, security, and resiliency with its deep integration with z/OS on System z servers. Beyond the existing DB 2 support for z. EC 12 DB 2 plans further enhancements designed to improve performance in two ways: 1) using pageable large (1 MB) pages and Flash Express and 2) enabling support of 2 GB pages. • IBM intends to update CICS Transaction Server for z/OS , providing new application, platform and policy capabilities that can help clients build private clouds from new and existing CICS applications. This capability is intended to assist CICS clients deploy new and updated CICS applications faster, more easily, and with greater levels of confidence.
