DRAFT Metrics of IT Equipment — Computing and Energy Performance

This report summarizes work to date on the development of a simple, standard method of characterizing the degree to which a single server reduces its energy consumption when operating at low levels of computation compared to what it consumes at peak computing capacity (the “part-load” condition). The goal is to bring more attention and rigor to the issue, and lead to future servers which save energy by having lower power use at part load.
