The 2010s

z/VSE V4.3 has shipped in November 2010, and z/VSE V5.1 has shipped about a year later, in November 2011. This new version introduced 64-bit virtual addressing among other enhancements. z/VSE V5.2 has shipped in April 2014, and again delivered several new features and enhancements.

Many customers started to adapt the VSE strategy of leveraging the combination of z/VSE and Linux on z Systems. The strategy embraces a robust z/VSE that helps protect customer investments in core VSE applications, a VSE that uses standards to help integrate VSE and the mainframe into the customer's network, and a VSE that can be extended by exploiting other platforms - including Linux on z Systems.

Where Does VSE Go From Here?

The z/VSE operating system is used by a large number of IBM z Systems customers around the world. Most run a significant portion of their business applications on z/VSE in an LPAR or under z/VM. For that reason, IBM is committed to maintaining proven standards of excellence in the support and maintenance of z/VSE into the future. Customers can continue running their core, proven business-critical applications on z/VSE with confidence.

z/VSE has a heritage of 50 years of ongoing refinements and innovation. The most current release, z/VSE Version 6.1, has been generally available since November 2015 and has integrated several enhancements to the product including new versions of CICS TS and TCP/IP. These newest releases confirm our successful z/VSE "PIE" strategy: Protect existing investments, Integrate with other systems, and Extend for new workloads.
