This IBM® Redbooks® publication discusses the IBM System z10™ Enterprise Class, which offers a continuation of IBM scalable mainframe servers. Based on z/Architecture®, the IBM System z10 Enterprise Class (z10 EC) server provides major extensions by:

- Increasing the maximum number of processor units

- Providing fixed HSA where all devices, channel subsystems, and multiple subchannel sets are defined, thus better supporting dynamic changes

- Providing a base for major server consolidation by further removing memory, processor, and channel constraints

- Increasing the flexibility of capacity upgrades

This book provides an overview of the z10 EC and its functions, features, and associated software support. Greater detail is offered in areas relevant to technical planning.

This book is intended for systems engineers, consultants, planners, and anyone wanting to understand the System z10 Enterprise Class functions and plan for their usage. It is not intended as an introduction to mainframes. Readers are expected to be generally familiar with existing IBM System z technology and terminology.
