This chapter starts by introducing the fundamentals of power and efficiency measurements and then describes a power and performance benchmark methodology developed by the SPECpower committee for commodity servers. It is designed to characterize and rate the energy efficiency of a system under test for multiple load levels, showcasing load level differences in system behavior regarding energy efficiency. The methodology was first implemented in the SPECpower_ssj 2008 benchmark and later extended with more workloads, metrics, and other application areas for the SPEC Server Efficiency Rating Tool (SERT) suite. The SERT suite was developed to fill the need for a rating tool that can be utilized by government agencies in their regulatory programs, for example, the U.S. Environmental Protection Agency (EPA) for the use in their ENERGY STAR program for servers.
