Overview
This IBM Redbook introduces the IBM System z9 109 (z9-109), which
offers a continuation of the IBM scalable mainframe servers. The
z9-109 server is based on z/Architecture and provides extensions to
the architecture. In addition to increased performance and
expansion options, particular emphasis has been placed on the
integration of the z9-109 into a complete system and software
environment.
This document provides basic information about new hardware
functions and features, associated software support, and migration
considerations. It is intended for systems engineers, hardware
planners, and anyone else needing to understand the new z9-109
system elements and plan for their usage. This document is not
intended as an introduction to mainframes. Readers are expected to
be generally familiar with current zSeries technology and
terminology.
