Support By Function; Single System Image - IBM z13s Technical Manual

Function
InfiniBand coupling links 12x at a
distance of 150 m (492 ft.)
InfiniBand coupling links 1x at
unrepeated distance of 10 km (6.2 miles)
Dynamic I/O support for InfiniBand
CHPIDs
CFCC Level 21
a. Toleration support PTFs are required.
b. SUSE Linux Enterprise Server 12 and RHEL can support up to 256 PUs (IFLs or CPs).
c. 4 TB of real storage is supported per server.
d. Red Hat (RHEL) supports a maximum of 3 TB.
e. z/TPF supports only AES-128 and AES-256.
f. z/TPF supports only SHA-1 and SHA-256.
g. Service is required.
h. Supported only when running in accelerator mode.
i. On z13s servers, the CHPID statement of HiperSockets devices requires the keyword VCHID.
The z13s IOCP definitions therefore must be migrated to support the HiperSockets definitions
(CHPID type IQD). VCHID specifies the virtual channel identification number associated with
the channel path. Valid range is 7E0 - 7FF. VCHID is not valid on z Systems before z13s
servers.
j. Applicable to guest operating systems.
k. IBM is working with its Linux distribution partners to include support in future Linux on z Systems
distribution releases. Check the Linux distribution partners for the latest information.
l. Supported by SUSE Linux Enterprise Server 11.
m. Supported by SUSE Linux Enterprise Server 11 SP3 and RHEL 6.4.
n. For more information, see 7.3.39, "FCP provides increased performance" on page 267.
o. Requires PUT 5 with program temporary fixes (PTFs).
p. Requires PUT 8 with PTFs.
q. Supported by SUSE Linux Enterprise Server 11 SP1, SUSE Linux Enterprise Server 10 SP4,
and RHEL 6, RHEL 5.6.
r. Supported by SUSE Linux Enterprise Server 11, SUSE Linux Enterprise Server 10 SP2,
RHEL 6, and RHEL 5.2.
s. Supported by SUSE Linux Enterprise Server 11 SP2, SUSE Linux Enterprise Server 10 SP4,
RHEL 6, and RHEL 5.2.
t. Requires PUT 4 with PTFs.
u. SSTP is supported in z/TPF with APAR PJ36831 in PUT 07.
