Features: Usage of certain features depends on the operating system. In all cases, PTFs might be required with the operating system level that is indicated. Check the z/OS, z/VM, z/VSE, and z/TPF subsets of the 2964DEVICE PSP buckets. The PSP buckets are continuously updated, and contain the latest information about maintenance.
Hardware and software buckets contain installation information, hardware and software service levels, service guidelines, and cross-product dependencies.
For Linux on z Systems distributions, consult the distributor’s support information.
|
Capacity: For the capacity of any z/VM logical partition (LPAR), and any z/VM guest, in terms of the number of Integrated Facility for Linux (IFL) processors and central processors (CPs), real or virtual, you might want to adjust the number to accommodate the processor unit (PU) capacity of the z13.
z/VM V6R3 and IBM z Unified Resource Manager: In light of the IBM cloud strategy and adoption of OpenStack, the management of z/VM environments in zManager is now stabilized and will not be further enhanced. Accordingly, zManager does not provide systems management support for z/VM V6R2 on IBM z13 or for z/VM V6.3 and later releases. However, zManager continues to play a distinct and strategic role in the management of virtualized environments that are created by integrated firmware hypervisors (IBM Processor Resource/Systems Manager (PR/SM), PowerVM, and System x hypervisor based on a kernel-based virtual machine (KVM)) of the z Systems.
Statements of Direction1:
•Removal of support for Expanded Storage (XSTORE): z/VM V6.3 is the last z/VM release that supports Expanded Storage (XSTORE) for either host or guest use. The z13 will be the last high-end server to support Expanded Storage (XSTORE).
•Stabilization of z/VM V6.2 support: The IBM z13 server family is planned to be the last z Systems server supported by z/VM V6.2 and the last z Systems server that will be supported where z/VM V6.2 is running as a guest (second level). This is in conjunction with the statement of direction that the IBM z13 server family will be the last to support ESA/390 architecture mode, which z/VM V6.2 requires. z/VM V6.2 will continue to be supported until December 31, 2016, as announced in announcement letter # 914-012.
•Product Delivery of z/VM on DVD/Electronic only: z/VM V6.3 is the last release of z/VM that is available on tape. Subsequent releases will be available on DVD or electronically.
•Enhanced RACF password encryption algorithm for z/VM: In a future deliverable, an enhanced RACF/VM password encryption algorithm is planned. This support is designed to provide improved cryptographic strength by using AES-based encryption in RACF/VM password algorithm processing. This planned design is intended to provide better protection for encrypted RACF password data if a copy of RACF database becomes inadvertently accessible
•z/VM V6.3 Multi-threading CPU Pooling support: z/VM CPU Pooling support will be enhanced to enforce IFL pool capacities as cores rather than as threads in an environment with multi-threading enabled.

Important1: The z13 is the last z Systems server to support FICON Express 8 channels. Enterprises should begin migrating from FICON Express8 channel features (FC 3325 and FC 3326) to FICON Express16S channel features (FC 0418 and FC 0419). FICON Express 8 will not be supported on future high-end z Systems servers as carry-forward on an upgrade.

Statement of Direction1: In the first half of 2015, IBM intends to deliver a GDPS/PPRC multiplatform resiliency capability for customers who do not run the z/OS operating system in their environment. This solution is intended to provide IBM z Systems customers who run z/VM and their associated guests, for instance, Linux on z Systems, with similar high availability and disaster recovery benefits to those who run on z/OS. This solution will be applicable for any IBM z Systems announced after and including the zBC12 and zEC12.
|
Important: Use the previous z Systems ARCHITECTURE or TUNE options for C/C++ programs if the same applications run on both the z13 and on previous z Systems servers. However, if C/C++ applications run only on z13 servers, use the latest ARCHITECTURE and TUNE options to ensure that the best performance possible is delivered through the latest instruction set additions.
|
Statement of Direction1: IBM intends to deliver IBM zAware support for z/VM. This future release of IBM zAware is intended to help identify unusual behaviors of workloads running on z/VM to accelerate problem determination and improve service levels.
|
Consideration: Because coupling link connectivity to System z10 and previous systems is not supported, introduction of z13 into existing installations might require more planning. Also, consider the level of CFCC. For more information, see “Coupling link considerations” on page 175.
|
Statement of Direction1: At the time of writing, IBM plans to support up to 256 Coupling CHPIDs on z13 short, that is, twice the 128 coupling CHPIDs that are supported on zEC12. Each CF image continues to support a maximum of 128 coupling CHPIDs.

|
Statement of Direction1: In a future deliverable, IBM intends to deliver support to enable z/VM guests to use the Vector Facility for z/Architecture (SIMD).
|
Remember: The need for ICKDSF Release 17 applies even to systems that are not part of the same sysplex, or are running an operating system other than z/OS, such as z/VM.
