IBM ^zSeries is the enterprise class e-business server optimized for the 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 z990 server enhances performance by exploiting new technology through many design enhancements. With a new superscalar microprocessor and the CMOS 9S-SOI technology, the z990 is designed to further extend and integrate key platform characteristics such as dynamic

exible partitioning and resource management in mixed and unpredictable workload environments, providing scal- ability, high availability and Quality of Service to emerging e-business applications such as WebSphere®, Java and Linux.

The z990 has 4 models available as new build systems and as upgrades from the z900.

The four z990 models are designed with a multi-book system structure which provides up to 32 Processor Units (PUs) that can be characterized prior to the shipment of the machine as either Central Processors (CPs), Integrated Facility for Linux (IFLs), or Internal Coupling Facilities (ICFs).
