Overview

z/VSE is the follow-on product for customers with VSE/ESA™ installed. It is expected to be the basis for all future VSE development. z/VSE is designed to exploit select zSeries® hardware technology to help address the needs of VSE clients with growing core VSE workloads and/or exploit Linux on zSeries for e-business on demand™ solutions and infrastructure simplification.

IBM plans to allow IBM eServer zSeries servers with z/VSE Version 3 Release 1 to attach industry-standard Small Computer System Interface (SCSI) devices via zSeries Fibre Channel Protocol (FCP) channels. z/VSE will be designed to attach selected SCSI disks in addition to Extended Count-Key-Data (ECKD™) and Fixed Block Architecture (FBA) disks. z/VSE V3.1 plans to support FCP-attached SCSI disks in the IBM TotalStorage® Enterprise Storage Server™ (ESS).

The objective of SCSI support is to offer clients more storage choices as well as help lower Total Cost of Ownership (TCO). z/VSE SCSI support is expected to complement SCSI support in Linux on zSeries. z/VSE SCSI support is designed to be transparent to user-written programs, z/VSE components, subsystems, and vendor interfaces. z/VSE V3.1 is expected to support SCSI disks for data files only. User-written programs will use VSE's existing FBA support to access SCSI disks.

z/VSE is planned to continue to expand the focus on interoperability that began with VSE/ESA Version 2 Release 5, and continued with VSE/ESA Version 2 Release 6 and VSE/ESA Version 2 Release 7. With z/VSE V3.1, IBM plans to continue to ship CICS/VSE® V2.3 together with CICS® TS for VSE/ESA at no additional charge.

z/VSE plans to offer simplified packaging. Language Environment® for VSE/ESA will become a component of VSE Central Functions. Where supported, customers will have their choice of electronic Internet delivery and CD-ROM shipment options, in addition to 3480 compressed and 3590 cartridge tapes.

z/VSE V3.1 is designed to support IBM eServer zSeries, as well as S/390® Multiprise® 3000 and S/390 Parallel Enterprise Server™ Generation 5 and 6, or equivalent.

z/VSE can execute in 31-bit mode only. It does not implement z/Architecture™, and specifically does not implement 64-bit mode capabilities. z/VSE is designed to exploit selected features of IBM zSeries hardware.

Description

z/VSE is the follow-on product for all clients with VSE/ESA installed. It is planned to become the basis for all future VSE development. z/VSE will exploit innovative zSeries technology to help address the needs of VSE clients with growing core zSeries workloads and/or those who want to exploit Linux on zSeries for new on demand operating environments and infrastructure simplification.

z/VSE Version 3 Release 1 is intended to be capable to exploit the following zSeries technology:

  • SCSI disks attached to zSeries FCP channels (FCP CHPID type)

    Fibre Channel Protocol (FCP) channels are designed to allow zSeries servers to attach industry-standard Small Computer System Interface (SCSI) devices using the FCP protocol. A typical topology can consist of one or more FCP channels, a switch, and a controller with one or more ports and one or more SCSI devices. FCP channels are FICON™ Express cards that have been personalized with FCP firmware. z/VSE is designed to attach selected SCSI, Extended Count-Key-Data (ECKD), and Fixed Block Architecture (FBA) disks. z/VSE V3.1 is planned to support the SCSI disks that are part of the IBM TotalStorage Enterprise Storage Server (ESS).

    z/VSE V3.1 will support SCSI-FCP disk for data files only. z/VSE SCSI-FCP support is designed to be transparent to user-written programs, z/VSE components, and subsystems. User-written programs will use VSE's existing Fixed Block Architecture (FBA) support to access SCSI disks. ECKD disks are still required to hold the operating system components and files.

  • HiperSockets, including HiperSockets Spanned Channels (VSE/ESA Version 2 Release 7 and later)

    With HiperSockets, TCP/IP traffic is expected to travel between LPARs and virtual servers at memory speed, rather than network speed. Spanned Channels allow z/VSE to use HiperSockets that link LPARs or virtual servers using different Logical Channel Subsystems (LCSSs).

  • PCI Cryptographic Accelerator (PCICA) (VSE/ESA Version 2 Release 7 and later)

    PCICA cards are designed to provide an RSA assist for increased Secure Sockets Layer (SSL) throughput. SSL transparently uses PCICA cards if available.

  • Adapter interruptions for OSA-Express (OSD CHPID type) (VSE/ESA Version 2 Release 7 and later)

    This zSeries advance is intended to provide a more efficient technique for handling I/O interrupts. It is designed to reduce I/O path lengths and overhead.

  • Open Systems Adapter Integrated Console Controller (OSA-ICC) (VSE/ESA Version 2 Release 6 and later)

    OSA-ICC is designed to eliminate the need for a non-SNA 3174 controller, and may replace existing 2074 controllers. OSA-ICC support may help reduce TCO and contribute to infrastructure simplification.

  • OSA-Express, including Ethernet and Token-Ring (VSE/ESA Version 2 Release 6 and later)

  • Up to 30 LPARs (VSE/ESA Version 2 Release 6 and later)

    Additional LPARs provide additional flexibility.

  • Up to four Logical Channel Subsystems (VSE/ESA Version 2 Release 6 and later)

    With multiple LCSSs, z890 and z990 servers can attach up to 1024 channels. However, any single instance of z/VSE remains limited to 256 channels.

  • FICON and FICON Express (FC and FCV CHPID types) (VSE/ESA Version 2 Release 6 and later)

    FICON channels may allow higher I/O bandwidth.

z/VSE can execute in 31-bit mode only. It does not implement z/Architecture, and specifically does not implement 64-bit mode capabilities. z/VSE is designed to exploit selected features of IBM zSeries hardware.

IBM z/VSE is planned to continue and advance the focus on interoperability that began with VSE/ESA Version 2 Release 5, and continued with VSE/ESA Version 2 Release 6 and VSE/ESA Version 2 Release 7. As part of the investment protection strategy of z/VSE Version 3 Release 1, IBM intends to continue shipping CICS/VSE V2.3 along with CICS Transaction Server for VSE/ESA V1.1.1 at no additional charge.

z/VSE is planned to simplify VSE packaging. Language Environment for VSE/ESA will become a component of VSE Central Functions.

z/VSE V3.1 is designed to allow Fast Service Upgrade (FSU) from VSE/ESA Version 2 Release 7 and VSE/ESA Version 2 Release 6 using equivalent ECKD disks. However, FSU will not be allowed from ECKD to SCSI-FCP disks.

z/VSE V3.1 is designed to support eServer zSeries, as well as S/390 Multiprise 3000 and S/390 Parallel Enterprise Server Generation 5 and 6, or equivalent.

All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice.

Product positioning

Beginning with VSE/ESA Version 2 Release 5, a key element of the VSE strategy is to help clients protect their extensive investments in core VSE applications, data, and IT skills, as well as business processes and end-user training. A second major element of the VSE strategy is to help enable clients to implement new solutions in a three-tier, hybrid environment that leverages existing VSE information assets.

Recent enhancements have been designed to improve interoperability between VSE and any Java™-capable platform. Interoperability can help clients simplify their IT infrastructure. Infrastructure simplification may help reduce cost, disruption, and risk. It may help increase productivity and lessen time-to-market.

Integrated hybrid solutions may consist of a zSeries running z/VSE plus the user's choice of any Java-capable server for the middle tier. For example, the middle tier platform may be an IBM eServer

  • zSeries (the same or a different server with z/OS® or Linux)
  • pSeries® (AIX® or Linux)
  • xSeries® (Windows™ or Linux)
  • iSeries™ (OS/400® or Linux)

z/VSE is designed for VSE clients with growth opportunities. "Growth" may be generated by some combination of:

  • VSE workload
    • Added volumes, new users, and new or enhanced core applications
    • Associated IT activity (such as test, backup, printing, and file transfer)
  • Linux workload
    • New e-business on demand solutions (such as WebSphere® Application Server and DB2 Universal Database®)
    • New line-of-business applications (such as ERP and CRM)
    • Application development and test
    • Infrastructure simplification, including consolidation of existing distributed workload (such as file/print server, mail, firewalls, and DNS)

Responding to growth opportunities, z/VSE is planned to exploit advanced eServer zSeries and TotalStorage technology.

For example, an especially attractive environment consists of

  • z/VSE (running on "standard" engines), linked via HiperSockets to
  • Linux on zSeries (running on Integrated Facility for Linux [IFL] engines).

This powerful model, perhaps implemented using innovative IBM technology such as

  • IBM eServer zSeries 890 server and
  • SCSI-FCP storage,

can provide a compelling solution for both growth-oriented and cost-conscious VSE clients.

z/VSE can execute in 31-bit mode only. It does not implement z/Architecture, and specifically does not implement 64-bit mode capabilities. z/VSE is designed to exploit selected features of IBM zSeries hardware.

Planning information

Preview announcements are made solely to provide clients with important planning information. Previews contain no dates or prices. However, the following additional information is being provided to give customers essential information to use in their planning processes. These statements do not represent a commitment from IBM. They are based on IBM's current plans and those plans are subject to change or withdrawal without notice.

It is IBM's intent that monthly prices for z/VSE V3.1 will be "net neutral." That is, clients with equivalent software configurations, running on equivalent servers, under equivalent terms and conditions, will see no net increase in prices compared to VSE/ESA™ Version 2. This represents an objective, not an absolute assurance. Specific client situations and contracts may differ, and unique conditions may occur for a variety of reasons.

IBM intends to deliver z/VSE V3.1 in 2005. Customers are encouraged to avoid delaying hardware or software upgrades in the interim. It is suggested that customers consider proceeding with any plans they have to install VSE/ESA V2.7 in 2004. Similarly, customers interested in the z890 can install with VSE/ESA V2.7 and begin receiving the benefits of this highly granular server solution. The Fast Service Upgrade (FSU) process is planned to be available to z/VSE V3.1 from VSE/ESA V2.7 and VSE/ESA V2.6. Customers with these releases are expected to be able to use the FSU process to upgrade to z/VSE V3.1 when available.

z/VSE V3.1 clients are expected to have their choice of electronic Internet delivery or CD-ROM in addition to 3480 compressed or 3590 tape cartridge shipment options. Where supported, electronic Internet delivery of VSE/ESA Version 2 Release 7 is now available through ShopzSeries at
