Models and Metrics for Energy - Efficient Computing . In Marvin

Over the past decade, however, power and energy have begun to severely constrain component, system, and data center designs. When a data center reaches its maximum provisioned power, it must be replaced or augmented at great expense. In desktops, power consumption and heat contribute to electricity costs as well as noise. Better equipment design and better energy management policies are needed to address these concerns. This chapter will detail current efforts in energy-efficiency metrics and in power and thermal modeling, delving into specific case studies for each. Various benchmarks are explained and their effectiveness at measuring power requirements is discussed. 1. I ntroduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 160 2.
