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

z/VSE

z/VSE 4.1, the latest advance in the ongoing evolution of VSE, is designed to help address needs of VSE clients with growing core VSE workloads and/or those who wish to exploit Linux on System z for new, Web-based business solutions and infrastructure simplifi cation.

z/VSE 4.1 is designed to support:

z/Architecture mode only

64-bit real addressing and up to 8 GB of processor storage

System z encryption technology including CPACF, con- fi gurable Crypto Express2, and TS1120 encrypting tape

Midrange Workload License Charge (MWLC) pricing, including full-capacity and sub-capacity options

IBM has previewed z/VSE 4.2. When available, z/VSE 4.2 is designed to help address the needs of VSE clients with growing core VSE workloads. z/VSE V4.2 is designed to support:

More than 255 VSE tasks to help clients grow their CICS workloads and to ease migration from CS/VSE to CICS Transaction Server for VSE/ESA

Up to 32 GB of processor storage

Sub-Capacity Reporting Tool running “natively”

Encryption Facility for z/VSE as an optional priced feature

IBM System Storage TS3400 Tape Library (via the TS1120 Controller)

IBM System Storage TS7740 Virtualization Engine Release 1.3

z/VSE V4.2 plans to continue the focus on hybrid solutions exploiting z/VSE and Linux on System z, service-oriented architecture (SOA), and security. It is the preferred replace- ment for z/VSE V4.1, z/VSE V3, or VSE/ESA. It is designed to protect and leverage existing VSE information assets.

z/TPF

z/TPF is a 64-bit operating system that allows you to move legacy applications into an open development environ- ment, leveraging large scale memory spaces for increased speed, diagnostics and functionality. The open develop- ment environment allows access to commodity skills and
