Data centers form the backbone of information management in every sector of the economy, and their energy consumption has been of concern to governments and the telecom industry. This chapter introduces data center energy efficiency, including the main components and operating environments in data centers, as well as the standards, thermal guidelines, and metrics used to quantify the energy efficiency. This chapter also presents the major cooling methods used in the industry to improve energy efficiency. A case study is discussed in which energy consumption of a medium-size primary data center at an academic campus is analyzed and compared with experimental measurements.
