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 IBM System z® family of mainframes, which includes these systems:

  • IBM zEnterprise® EC12 (zEC12)

  • IBM zEnterprise BC12 (zBC12)

  • IBM zEnterprise 196 (z196)

  • IBM zEnterprise 114 (z114)

  • IBM System z10® Enterprise Class (z10 EC)

  • IBM 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 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 July 23, 2013.

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