1 – TPF and zTPF use LCSS-0 only, but more than 15 LPARs are permitted. See APAR PJ29309 (included in z/TPF).

2 – VSE 2.7 exploits Thin Interrupts with 4Q04 SPE 3 – Web Deliverable for Secure Crypto

*– z/VSE can execute in 31-bit mode only. It does not implement z/Architecture, and specifically does not implement 64-bit mode capabilities.

IBM ^zSeries is the enterprise class e-business server optimized for integration, transactions and data of the next generation e-business world. In implement- ing the z/Architecture with new technology solutions, the zSeries models are designed to facilitate the IT business transformation and reduce the stress of business-to-busi- ness and business-to-customer growth pressure. The zSeries represents an advanced generation of servers that feature enhanced performance, support for zSeries Parallel Sysplex clustering, improved hardware man- agement controls and innovative functions to address e-business processing.

The z890 server, the latest addition to the zSeries family, takes advantage of the design enhancements and new technology of the z990 in a package that helps deliver excellent price/performance for those customers requiring a lower capacity entry point than that offered by the z990. With a new superscalar microprocessor and the CMOS 9S- SOI technology, the z890 is designed to further extend and integrate key platform characteristics such as dynamic

flexible partitioning and resource management in mixed and unpredictable workload environments, providing tra- ditional zSeries Quality of Service to emerging e-business applications such as WebSphere®, Java and Linux.

The IBM ^zSeries Application Assist Processor (zAAP), available on the IBM ^zSeries 990 (z990) and zSeries 890 (z890) servers, is an attractively priced specialized processing unit that provides strategic z/OS Java execution environment for customers who desire the powerful integration advantages and traditional Qualities of Service of the zSeries platform.

When confi gured with general purpose Central Processors (CPs) within logical partitions running z/OS, zAAPs can help you to extend the value of your existing zSeries investments and strategically integrate and run
