Software promotes scalability for virtualization on servers.
Press Release Summary:
With support for System z9 109, z/VM® v5.2 provides scalability for memory-constrained environments by effective utilization of more than 2 Gb of real memory. This offers constraint relief for virtual-server environments, including those with Linux(TM) on System z9 and zSeries guests. Along with SCSI disk support, software provides platform for integrating applications, data, and consolidating UNIX®, Windows(TM), and Linux workloads on one physical z9-109 or zSeries server.

Overview
IBM continues the evolution of its premier and world-class virtualization technology by providing a new release of z/VM®, Version 5 Release 2 (V5.2). An infrastructure for on demand computing environments can be deployed with IBM System z9(TM) 109 or zSeries® servers and visionary virtualization technology of z/VM.
z/VM V5.2 includes support for the new System z9 109 (z9-109) announced today and provides enhanced scalability for memory-constrained environments with more effective utilization of more than 2 GB of real memory. These improvements offer constraint relief for virtual-server environments that are memory-intensive, including those with large Linux(TM) on System z9 and zSeries guests. Additional changes have been made to improve performance and enhance Small Computer System Interface (SCSI) disk support when operating Linux and CMS as guests of z/VM V5.2.
z/VM V5 extends the strength of the System z9 and zSeries environment as an ideal platform for integrating applications and data and consolidating select UNIX®, Windows(TM), and Linux workloads on a single physical z9-109 or zSeries server. This can allow you to run tens to hundreds of Linux servers with the potential to support new workloads, achieve productivity gains, and lower IT costs. z/VM supports Linux on the mainframe and enables Linux servers to share hardware resources and use internal high-speed communications within the System z9 and zSeries environments.
Put the power of System z9 and zSeries environments combining partitioning and z/VM virtualization technology to work for you and help realize the benefits of workload isolation and resource sharing, including:
Reliability, availability, and serviceability of IBM mainframes
Flexibility to create as many as 60 logical partitions (LPARs)with z9-109
Ability to virtually partition each LPAR into hundreds or more virtual machines
Ability to virtualize processor, communication, memory, storage, I/O, and networking resources
Help with maximizing resources to achieve high system utilization
Advanced dynamic resource allocation
High-speed communications among LPARs and guests with HiperSockets(TM)
Advanced systems management, administration, and accounting tools
