Z/Vse; Z/Tpf; Linux On Z Systems - IBM z13s Technical Manual

Statements of Direction:
Removal of support for Expanded Storage (XSTORE): z/VM V6.3 is the last z/VM
release that supports XSTORE for either host or guest use. The IBM z13 and z13s
servers will be the last z Systems servers to support XSTORE.
Stabilization of z/VM V6.2 support: The IBM z13 and z13s servers are planned to be
the last z Systems servers 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 and z13s servers 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.

7.2.3 z/VSE

Support is provided by z/VSE V5R1 and later. Note the following considerations:
z/VSE runs in z/Architecture mode only.
z/VSE supports 64-bit real and virtual addressing.
z/VSE V5 has an architecture level set (ALS) that requires IBM System z9 or later.
z/VSE V6 has an ALS that requires IBM System z10 or later.
For a list of supported functions and their required support levels, seeTable 7-4 on page 239.

7.2.4 z/TPF

For a list of supported functions and their required support levels, see Table 7-4 on page 239.

7.2.5 Linux on z Systems

Linux on z Systems distributions are built separately for the 31-bit and 64-bit addressing
modes of the z/Architecture. The newer distribution versions are built for 64-bit only. Using the
31-bit emulation layer on a 64-bit Linux on z Systems distribution provides support for running
31-bit applications. None of the current versions of Linux on z Systems distributions (SUSE
Linux Enterprise Server 12 and 11, and Red Hat Enterprise Linux (RHEL) 7 and 6) require
z13s toleration support. Table 7-2 shows the service levels of SUSE and Red Hat releases
supported at the time of writing.
