Server Efficiency: Metrics for Computer Servers and Storage

Performance measures designed without regard to the enrgy used to produce work are a thing of the past. Now, with recognition of the importance of the energy consumed to produce the results, both the numerator and denominator in “performance per watt” are seen as critically important attributes of an IT platform. This book consolidates information on current server and storage subsystem energy benchmarks. Each chapter describes a metric, its target market, and includes examples of data generated from the subject benchmark or tool, along with guidance on interpreting the data. This book provides the information needed to select the best measure of performance and power for a variety of server applications.
