Abstract

The IBM z14 is the latest update in the storied history of IBM mainframes. Reliability, availability, security, and scalability are the foundation of the IBM mainframe line. System reliability and availability targets are in excess of 10 years, requiring rigorous chip characterization processes. In this paper, we discuss some of the many processes used to ensure that lifetime. An additional part of this reliability is power man- agement (PM). The 5.2-GHz high-power design of the central processo
