Chapter 1. Introducing IBM z13s servers 31
Linux on z Systems distributions:
– SUSE Linux Enterprise Server (SLES): SLES 12 and SLES 11.
– Red Hat Enterprise Linux (RHEL): RHEL 7 and RHEL 6.
– Customers should monitor for new distribution releases supported
For recommended and new Linux on z Systems distribution levels, see the following website:
http://www.ibm.com/systems/z/os/linux/resources/testedplatforms.html
The following operating systems will be supported on zBX Model 004:
An AIX (on POWER7) blade in IBM BladeCenter Extension Mod 004): AIX 5.3, AIX 6.1,
AIX 7.1 and later releases, and PowerVM Enterprise Edition
Linux (on IBM BladeCenter HX5 blade installed in zBX Mod 004):
– Red Hat RHEL 5.5 and later, 6.0 and later, 7.0 and later
– SLES 10 (SP4) and later, 11 SP1 and later, SLES 12 and later - 64 bit only
Microsoft Windows (on IBM BladeCenter HX5 blades installed in zBX Mod 004):
– Microsoft Windows Server 2012, Microsoft Windows Server 2012 R2
– Microsoft Windows Server 2008 R2 and Microsoft Windows Server 2008 (SP2)
(Datacenter Edition recommended) 64 bit only
Together with support for IBM WebSphere software, IBM z13s servers provide full support for
SOA, web services, Java Platform, Enterprise Edition, Linux, and Open Standards. The z13s
server is intended to be a platform of choice for the integration of the newest generations of
applications with existing applications and data.
z Systems software is also designed to take advantage of the many enhancements on z13
and z13s servers. Several platform enhancements have been announced with the z13:
KVM for IBM z Systems 1.1.1
z/VM Support
z/OS Support
KVM for IBM z Systems 1.1.1
KVM on z offers a number of enhancements announced with z13s servers for availability.
Because KVM support is evolving on z Systems, monitor for new enhancements to KVM and
Linux on z Systems distributions.
These enhancements are intended to use many of the innovations of the server. KVM on z
provides the following enhancements, among others:
Simultaneous multithreading (SMT) exploitation
Guest use of the Vector Facility for z/Architecture (SIMD)
Hypervisor enhancements that include support for iSCSI and NFS
Hypervisor Crypto use
Enhanced RAS capabilities such as improved first-failure data capture (FFDC)
Improved high availability configuration
Unattended installation of hypervisor
