History

z/VSE is built on a heritage of ongoing refinement and innovation that spans four decades. It is designed to protect and leverage customer investments in VSE information assets.

z/VSE Version 4 Release 2 (z/VSE V4.2) is designed to deliver highest qualities of service for transactions and data. z/VSE V4 is designed to address the needs of VSE clients with growing core VSE workloads and/or those who wish to exploit Linux on IBM System z for new, Web-based business solutions and infrastructure consolidation.

z/VSE is an important part of IBM's mainframe portfolio for smaller IBM mainframe clients with somewhat less demanding requirements. At the risk of oversimplification, z/VSE is similar to z/OS but smaller and less complex.

z/VSE V4.2 supports the new IBM System z10 Business Class (z10 BC) and IBM System z10 Enterprise Class (z10 EC), the IBM System z9 Enterprise Class (z9 EC) and System z9 Business Class (z9 BC) servers, as well as IBM eServer zSeries 990, 890, 900 and 800.

z/VSE V4.2 operates in z/Architecture mode only and supports 64-bit real addressing. It is designed to exploit up to 32 GB of processor storage.

z/VSE 4.2 doubles the number of VSE tasks to 512 and adds an LDAP client. It supports Parallel Access Volumes (PAV) feature of the IBM System Storage series DS8000 and DS6000.

z/VSE 4.2 supports advanced functions of IBM System Storage, including IBM System Storage DS8000 Full Disk Encryption, DS8000 FlashCopy SE (space efficient), IBM System Storage SAN Volume Controller, as well as the IBM System Storage TS4300 Tape Library and TS7700 Virtualization Engine-just to name a few.

z/VSE V4 offers Midrange Workload License Charge (MWLC) pricing, including sub-capacity pricing for clients running on IBM System z10 BC, z10 EC, z9 EC and z9 BC servers. IBM is delivering a new world class enterprise server designed to address the broadest range of business needs.

z/VSE V4.2 became generally available on October 17, 2008.
