Abstract

This IBM® Redbooks® publication describes the connectivity options that are available for use within and beyond the data center for the IBM Z® family of mainframes, which includes these systems:


  • IBM z15™ Model T01
  • IBM z15™ Model T02
  • IBM z14™
  • IBM z14 Model ZR1™
  • IBM z13®
  • IBM z13s®

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 IBM Z hardware announcement dated April 14, 2020.

This book is intended for data center planners, IT professionals, systems engineers, and network planners who are involved in the planning of connectivity solutions for IBM mainframes.
