IBM Mainframe Life Cycle History

How To


Summary

IBM Z mainframe hardware product marketing and service life cycle history since 1994.

Objective

Each family of the IBM Z mainframe hardware products has followed a similar life cycle pattern: product announcement, general availability, marketing withdrawal, and service discontinuance. Historically each mainframe generation has had a long life from general availability to service discontinuance, averaging over 11 years. In addition, family-to-family upgrade paths have also provided investment protection and extension of the asset life time.

This document provides a graphic summary and details of the mainframe product life cycle since the introduction of CMOS technology in 1994.

Latest revision:
April 5, 2022 - V2.8 - added z16 and hardware family upgrade path charts.
