Energy-aware service centers take into account energy con-sumption of infrastructures, machines, applications, storage systems, andall what constitutes a distributed computing architecture. The goal ofthe paper is to present the approach to energy eciency in data centersin the GAMES (Green Active Management of Energy in IT Service cen-tres) project. We show how Green Performance Indicators (GPIs), i.e.,properties that, continuously monitored, evidence the level of consumedenergy by the center's IT resources, can be the basis of a systematic ap-proach to increase energy eciency. The GPIs are the basis for improvingenergy eciency in several ways with adaptive actions and the paper dis-cusses how to achieve a higher level of green maturity, as prescribed, forinstance, in the GreenGrid Data Center Maturity Model (DCMM), basedon a usage-centric perspective in GPIs. The paper briey describes mon-itoring of GPIs and the adaptation actions adopted to reach the greengoals. Preliminary experimental results are discussed.
