IBM System z Connectivity Handbook

Book Description

This IBM Redbooks® publication discusses the connectivity options available for use within and beyond the data center for the following IBM System z family of mainframes:
zEnterprise® EC12 (zEC12)
zEnterprise 196 (z196)
zEnterprise 114 (z114)
System z10® Enterprise Class (z10 EC)
System z10 Business Class (z10 BC)

This book highlights the hardware and software components, functions, typical uses, coexistence, and relative merits of these connectivity features. It helps readers to understand the connectivity alternatives that are available when planning and designing their data center infrastructures.

The changes to this edition are based on the System z hardware announcement dated August 28, 2012.

This book is intended for data center planners, IT professionals, system engineers, technical sales staff, and network planners who are involved in the planning of connectivity solutions for System z servers.
