Preface
The IBM
Eserver
® zSeries® 990 scalable server provides major extensions to the existing
zSeries architecture and capabilities. The concept of Logical Channel Subsystems is added,
and the maximum number of Processor Units and logical partitions is increased. These
extensions provide the base for much larger zSeries servers.
This IBM® Redbook is intended for IBM systems engineers, consultants, and customers who
need to understand the zSeries 990 features, functions, availability, and services.
This publication is part of a series. For a complete understanding of the z990 scalable server
capabilities, also refer to our companion Redbooks™:
