2 z/VM and Linux on IBM System z: The Virtualization Cookbook for Red Hat Enterprise Linux 6.0

Many functions have been added to z/VM since Version 5.2. The following sections give a

brief summary of the functions added in the last three releases.

z/VM V6.1

z/VM V6.1, available since October 2009, is intended to be the base for all future z/VM

enhancements. This release implements a new Architecture Level Set (ALS) available only on

the IBM System z10® Enterprise Class server and System z10 Business Class server and

future generations of System z servers. Requiring z10 technology or later allows z/VM to take

advantage of newer hardware technology for future exploitation.

Enhancements in z/VM V6.1 provide:

򐂰 Enhanced performance of virtual networking environments running heavy guest-to-guest

streaming workloads

򐂰 Faster access to data when utilizing FICON® Express8

򐂰 Closer integration with IBM Systems Director to eliminate the need to download agents

and help simplify the installation of those agents

򐂰 Significantly better and more highly secure guest transactions when using Crypto

Express3 as compared to Crypto Express2

򐂰 Guest support for IBM System Storage® DS8000® Extended Address Volumes (EAVs) to

help simplify storage management and relieve address constraints

z/VM V5.4

z/VM V5.4, available since August 2008, provides major improvements when operating on

System z servers with large memory configurations. It improves scalability and can help

support increased workloads on IBM System z servers. This release uses new capabilities of

the System z10, including:

򐂰 Greater flexibility, with support for the new z/VM-mode logical partitions, allowing all

System z processor-types (CPs, IFLs, zIIPs, zAAPs, and ICFs) to be defined in the same

z/VM LPAR for use by various guest operating systems

򐂰 Capability to install Linux on System z from the HMC, which eliminates network setup or a

connection between an LPAR and the HMC

򐂰 Enhanced physical connectivity by exploiting all OSA-Express3 ports, helping service the

network and reducing the number of required resources

z/VM V5.4 dynamic memory upgrade support allows real memory to be added to a running

z/VM system, avoiding the need to shut down z/VM and its guests, deactivate the LPAR,

change its memory allocation, reactivate the LPAR, perform an IPL of z/VM, and restart its

guests. Memory can be added nondisruptively to individual guests that support the dynamic

memory reconfiguration architecture.

z/VM V5.3

z/VM V5.3 became generally available in June 2007. Scalability was extended to allow 256

GB of real memory, a total of 8 TB of virtual storage, and 32 real processors. z/VM V5.3 also

added support for the Collaborative Memory Management Assist (CMMA) on the z9® EC and
