z/VSE Version 5 Release 1 again demonstrates IBM's commitment to z/VSE clients.

This new version is another significant step in the ongoing evolution of z/VSE.

z/VSE V5.1 is designed to:

  • Provide 64-bit virtual addressing for growing workloads or new applications.
  • Exploit innovative IBM zEnterprise 196 technology.
  • Exploit enhanced IBM System Storage options.
  • Introduce an architectural level set (ALS) that requires IBM System z9 or later.

Enhancements planned for z/VSE V5.1 include:

  • 64-bit virtual addressing for applications.
    • 64-bit virtual support vastly increases the virtual storage available in a single address space.

      It is designed to meet the demands of z/VSE clients with growing workloads or those who wish to extend business opportunities with new 64-bit applications. 64-bit virtual support may also help clients who want to keep "more data in memory" to benefit from increased processor storage and processor speed available with the latest IBM System z servers.

      It is built upon z/Architecture® capabilities and 64-bit real addressing that were introduced with z/VSE V4.1.

    • z/VSE V5.1 fulfills the statement of direction in Software Announcement 210-313, dated October 05, 2010.
  • IPv6/VSE V1.1 exploitation of 64-bit virtual support.
  • Usage of architectural capabilities introduced with IBM System z9. This requires an architectural level set (ALS) of IBM System z9 or later.
  • Exploitation of innovative IBM zEnterprise 196 technology:
    • Static power save mode allows you to reduce the power consumption of IBM zEnterprise 196 when full performance is not required. z/VSE supports this feature for clients using MWLC pricing with the subcapacity pricing option.
    • z/VSE V5.1 is designed to provide 4096-bit RSA keys for use with configurable Crypto Express3 for enhanced security.
    • z/VSE V5.1 is designed to participate in a private intraensemble data network (IEDN) that connects all elements of a zEnterprise ensemble.
  • Exploitation of IBM System Storage options:
    • Copy Export function of the TS7700 Virtualization Engine Series for disaster recovery purposes
    • IBM Storwize V7000 Midrange Disk System
    • IBM XIV Storage System
  • Networking enhancements.

z/VSE V5.1 continues the z/VSE focus on scalability, security, service-oriented architecture (SOA), and hybrid solutions that exploit z/VSE and Linux® on System z.

z/VSE V5.1 extends the capabilities that were introduced with z/VSE V4.1 (z/Architecture mode and 64-bit real addressing) and continued with z/VSE V4.2 (more tasks) and z/VSE V4.3 (virtual storage constraint relief).

z/VSE V5.1 supports IBM System z servers:

  • IBM zEnterprise 196 (z196)
  • IBM System z10 Enterprise Class (z10 EC) and IBM System z10 Business Class (z10 BC)
  • IBM System z9 Enterprise Class (z9 EC) and IBM System z9 Business Class (z9 BC)

z/VSE Version 5 executes in z/Architecture mode only. z/VSE V5.1 can run in LPAR mode, or as a guest in any supported z/VM® release. z/VM V6.1 requires IBM System z10 or later. z/VSE V5.1 is the preferred follow-on VSE product for clients with z/VSE V4, z/VSE V3, or VSE/ESA™ installed. Clients may choose to use the Fast Service Upgrade (FSU) process when migrating from z/VSE V4.2 or z/VSE V4.3.

z/VSE V5.1 offers Midrange Workload License Charge (MWLC) pricing metrics, including a subcapacity option, for zEnterprise 196, System z10, and System z9 servers. The smallest z10 BC and z9 BC server capacity setting, A01, does not qualify for MWLC. Clients using the z10 BC and z9 BC capacity setting A01 will always pay a zSeries® Entry License Charge (zELC) for their IBM monthly license charge software.

Description
Bottom rule

Enhancements planned for z/VSE V5.1 include:

  • 64-bit virtual addressing

    z/VSE V5.1 is designed to provide 64-bit virtual addressing for user and vendor applications. With z/VSE V4, the concept of z/Architecture mode and 64-bit real addressing was introduced. Virtual addressing was still restricted to 31-bit. This means that the maximum size of a virtual address space in z/VSE V4 was 2 gigabytes (2 GB). Applications with a need for more virtual storage than the 2 GB address space provided sometimes used data spaces or implemented algorithms to manage storage within the 2 GB address space.

    64-bit virtual addressing vastly increases the virtual storage that is available within a single address space for growing or new workloads. It allows 64-bit applications to use virtual storage above the 2 GB address (the bar). It may help clients to keep "more data in memory" for improved performance and thus exploits increased processor storage available with the latest IBM System z servers.

    z/VSE V5.1 is designed to provide an application programming interface (API), the IARV64 macro, to manage storage above the bar.

    The area above the bar can be used for data only. Programs will continue to execute in the first 2 GB of an address space. Existing programs will continue to run unchanged.

    The IARV64 macro will be ported from IBM z/OS®. Programs that use the IARV64 macro with the functionality supported by z/VSE are designed to be compatible with z/OS. The supported IARV64 functionality includes private memory objects for use within a single address space as well as shared memory objects which can be shared among multiple address spaces. z/VSE will provide configuration commands to define the limits for memory objects.

  • Exploitation of innovative IBM zEnterprise 196 technology:
    • Static power save mode

      Static power save mode is a capability of the IBM zEnterprise 196 to help facilitate energy savings. With static power save mode clients have the ability to reduce the power consumption of the IBM zEnterprise 196 when full performance is not required. z/VSE V5.1 supports this feature for customers using Midrange Workload License Charge (MWLC) pricing metrics with the subcapacity pricing option. The support is also available with z/VSE V4.1 and later with PTFs.

    • 4096-bit RSA key support with configurable Crypto Express3 for enhanced security

      z/VSE V5.1 is designed to support 4096-bit RSA keys in addition to 1024-bit and 2048-bit RSA keys. TCP/IP for VSE/ESA 4096-bit RSA key support requires a Crypto Express3 adapter in either coprocessor or accelerator mode. z/VSE V5.1 e-business Connectors are designed to support 4096-bit RSA keys in addition to 1024-bit and 2048-bit RSA keys. z/VSE supports clear key RSA operations only.

      4096-bit RSA key support is also available with z/VSE V4.3 and PTF UK63070.

    • Intraensemble data network (IEDN)

      An IEDN is a private data network that connects all elements of a zEnterprise System ensemble. The IEDN is access-controlled using integrated virtual local area network (VLAN) support. The IEDN requires an OSA-Express3 10 Gigabit Ethernet (10 GbE) feature configured as CHPID type OSX (OSA-Express for zBX). Within a z/VM guest environment, z/VSE can transparently participate in an IEDN through a z/VM VSWITCH and existing TCP/IP connectivity. Support of CHPID type OSX now allows z/VSE V5.1 to participate in an IEDN in LPAR mode or as a z/VM guest with dedicated OSA-Express3 devices.

  • Exploitation of IBM System Storage options:
    • Copy Export function of the TS7700 Virtualization Engine Series

      The Copy Export function allows a copy of selected logical volumes written to the TS7700 Virtualization Engine to be removed and taken off-site for disaster recovery purposes. The benefits of volume stacking, which places many logical volumes on a physical volume, are retained with this function. In addition, since the data being exported is a copy of the logical volume, the logical volume data remains accessible by the production host systems. TS7700 Copy Export support fulfills several user requirements. z/VSE V5.1 is designed to support the Copy Export function of the TS7700 both in an LPAR and in a z/VM guest environment. z/VSE does not support policy management.

    • IBM Storwize V7000 Midrange Disk System

      Storwize V7000 is a midrange disk offering built on IBM System SAN Volume Controller (SVC) technology. It can now be attached through Fibre Channel (FC) switches to z/VSE using Fibre Channel Protocol (FCP) subchannels. z/VSE supports Storwize V7000 (SCSI) devices for system use (IPLable z/VSE system devices) and as data devices. z/VSE is designed to support Storwize V7000 devices in both an LPAR and a z/VM guest environment.

      z/VSE Storwize V7000 support is available with z/VSE V4.2 and later.

    • IBM XIV Storage System

      A high-end open disk system, XIV Storage System can now be attached through FC switches to z/VSE using FCP subchannels. z/VSE supports XIV (SCSI) devices for system use (IPLable z/VSE system devices) and as data devices. This support eliminates the need for z/VSE to access XIV devices through the SVC. z/VSE is designed to support XIV devices in both an LPAR and a z/VM guest environment.

      z/VSE XIV support is available with z/VSE V4.2 and later.

  • Networking enhancements

    z/VSE V4.3 introduced the Fast Path to Linux on System z (Linux Fast Path) function which allows selected TCP/IP applications to communicate with a TCP/IP stack on Linux on System z without requiring a TCP/IP stack on z/VSE. z/VSE 5.1 is designed to add IPv6 support to the Linux Fast Path function.

  • IPv6/VSE V1.1 enhancements:
    • Large TCP window support. IPv6/VSE is designed to support TCP window sizes of 64K (default) or optionally 1 MB, 2 MB, or 4 MB. Large TCP windows can increase throughput of inbound data transfers by reducing TCP window congestion.
    • 64-bit virtual addressing support. When running under z/VSE 5.1, large TCP window storage is transparently allocated above the bar.

Migration from CICS/VSE® V2.3 to CICS® Transaction Server for VSE/ESA on z/VSE V4.2:

Starting with z/VSE V4.3, CICS/VSE V2.3 is no longer offered as part of the z/VSE package. The CICS coexistence environment was also removed with z/VSE V4.3.

Improvements in z/VSE V3 and V4.2, including BSM security enhancements, additional VSE tasks, and DOS/VS RPG II support for CICS Transaction Server (TS), offer you the capability of migrating your CICS/VSE programs on z/VSE V4.2 prior to performing an upgrade to z/VSE V5.1. Clients migrating to CICS TS might benefit from virtual storage constraint relief addressed in z/VSE V4.3.

Top rule
Product positioning
Bottom rule

z/VSE adheres to the strategy of "Protect, Integrate, and Extend" -- in short "PIE."

  • Protect focuses on investment protection. z/VSE clients should be able to exploit the latest IBM System z and IBM System Storage technology to enhance and grow core z/VSE environments.
  • Integrate enables seamless integration. z/VSE clients should be able to extend their core z/VSE information assets into their overall IT system and network.
  • Extend refers to adding new solutions. z/VSE clients should be able to extend their core z/VSE solutions with solutions that exploit the advanced, standards-based capabilities of any platform, especially Linux on System z.

The "PIE strategy" is fundamentally based on an open hybrid model. This hybrid model can give you the best of both worlds: it helps to protect your z/VSE investments as you exploit the capabilities of complementary platforms. z/VSE plus Linux on System z is a compelling combination.

z/VSE Version 5.1 will significantly increase the capabilities for growing workloads while protecting existing investments in applications and data. 64-bit virtual addressing together with the exploitation of the innovative zEnterprise technology and IBM System Storage options will increase the choice to effectively manage the cost of providing the IT services your business needs.

You can operate and maintain the existing operations on which your business depends, deploy new workloads, and provide the new IT services that your changing and evolving business requires to innovate and gain competitive advantage. z/VSE Version 5.1 continues to help you introduce competitive new IT solutions at low cost, at low risk, and with fast time to market.
