Server Software supports Linux workloads/communications.
Press Release Summary:
Serving as platform for consolidating UNIX®, Windows(TM), and Linux workloads on one physical zSeries server, z/VM® v5.1 enables infrastructure for e-business on demand(TM) environments to be deployed with virtualization technology. Software supports Linux on mainframe and can enable Linux servers to share hardware resources and use internal communications within zSeries environment. It also lets users logically partition zSeries processors to support up to 30 logical partitions.
Original Press Release:

Overview
IBM continues the evolution of its premier and world-class zSeries® virtualization by providing a new version of z/VM®, Version 5 Release 1 (V5.1). An infrastructure for e-business on demand(TM) environments can be deployed with IBM eserver zSeries servers and visionary virtualization technology in z/VM V5.1, which includes support for the new IBM eserver zSeries 890 (z890) and enhancements to the z990 announced today.
You may benefit from the lower entry price and the new engine-based Value Unit pricing announced for z/VM V5.1, which replaces the per-engine pricing model that is available with z/VM V4. Engine-based Value Unit pricing is designed to provide a decreasing price curve as hardware capacities and workload grow, which may help improve price/performance.
z/VM V5.1 extends the strength of the zSeries environment as an ideal platform for consolidating select UNIX®, Windows(TM), and Linux workloads on a single physical 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 can enable Linux servers to share hardware resources and use internal high-speed communications within the zSeries environment.
z/VM V5.1 maintains the focus of providing innovative function for Linux servers hosted by z/VM. Installing from a DVD to Small Computer System Interface (SCSI) disks and operating z/VM and Linux from SCSI disks may help you reduce your total cost of computing. A new publication will be available to help get you started deploying Linux guests on z/VM more quickly.
Put the power of zSeries server 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 zSeries servers
· Flexibility to logically partition zSeries processors to support up to 30 logical partitions (LPARs)
· Ability to virtually partition each LPAR using z/VM to support many 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
· Advanced systems management, administration, and accounting tools
