A Power Benchmarking Study on the IBM System z9: Applying Energy Efficiency Metrics to Performance

Overview

Over the past few years energy efficiency in the data center has become one of the top concerns for IT managers. As the cost of power grows significantly, the application of energy efficiency to systems performance becomes a metric that can not be ignored. IBM has long been a champion of energy efficiency and the IBM System z9 is an outstanding platform for the integration of power efficiency and performance. This paper will demonstrate the role of the IBM System z9 as an excellent platform for power efficiency and performance, discuss tools used for measuring z9 power, highlight a Java power benchmarking study on this platform, and analyze client server consolidation as an energy management strategy.
