z/VM

z/VM V5.4 is designed to extend its System z virtualization technology leadership by exploiting more capabilities of System z servers including:

•Greater fl exibility, with support for the new z/VM-mode logical partitions, allowing all System z processor-types (CPs, IFLs, zIIPs, zAAPs, and ICFs) to be defi ned in the same z/VM LPAR for use by various guest operating sys- tems

•Capability to install Linux on System z as well as z/VM from the HMC on a System z10 that eliminates the need for any external network setup or a physical connection between an LPAR and the HMC

•Enhanced physical connectivity by exploiting all OSA- Express3 ports, helping service the network and reduc- ing the number of required resources.

•Dynamic memory upgrade support that allows real memory to be added to a running z/VM system. With z/VM V5.4, memory can be added non-disruptively to individual guests that support the dynamic memory reconfi guration architecture. Systems can now be confi gured to reduce the need to re-IPL z/VM. Processors, channels, OSA adapters, and now memory can be dynamically added to both the z/VM system itself and to individual guests.

The operation and management of virtual machines has been enhanced with new systems management APIs, improvements to the algorithm for distributing a guest’s CPU share among virtual processors, and usability enhancements for managing a virtual network.

Security capabilities of z/VM V5.4 provide an upgraded LDAP server at the functional level of the z/OS V1.10 IBM Tivoli® Directory Server for z/OS and enhancements to the RACF Security Server to create LDAP change log entries in response to updates to RACF group and user profiles, including user passwords and password phrases. The z/VM

SSL server now operates in a CMS environment, instead of requiring a Linux distribution, thus allowing encryption ser- vices to be deployed more quickly and helping to simplify installation, service, and release-to-release migration.

The z/VM hypervisor is designed to help clients extend the business value of mainframe technology across the enter- prise by integrating applications and data while providing exceptional levels of availability, security, and operational ease. z/VM virtualization technology is designed to provide the capability for clients to run hundreds to thousands of Linux servers in a single mainframe, together with other System z operating systems such as z/OS, or as a large- scale Linux-only enterprise-server solution. z/VM V5.4 can also help to improve productivity by hosting non-Linux workloads such as z/OS, z/VSE, and z/TPF.

August 5, 2008, IBM announced z/VM 5.4. Enhancements in z/VM 5.4 include:

•Increased fl exibility with support for new z/VM-mode logical partitions

•Dynamic addition of memory to an active z/VM LPAR by exploiting System z dynamic storage-reconfi guration capabilities

•Enhanced physical connectivity by exploiting all OSA- Express3 ports

•Capability to install Linux on System z from the HMC without requiring an external network connection

•Enhancements for scalability and constraint relief

•Operation of the SSL server in a CMS environment

•Systems management enhancements for Linux and other virtual images
