Energy accounts for a significant fraction of the operational costs of a data center, and data center operators are increasingly interested in moving towards low-power designs. Two distinct approaches have emerged towards achieving this end: the powerproportional approach focuses on reducing disk and server power consumption, while the green data center approach focuses on reducing power consumed by support-infrastructure like cooling equipment, power distribution units, and power backup

Our solution enforces power-proportionality at the granularity of a rack or even an entire containerized data center; thus, we power down not only idle IT equipment, but also their associated support-infrastructure. We show that it is practical today to design data centers to power down idle racks or containers-and in fact, current online service trends strongly enable this model. Finally, we show that our approach combines the energy savings of power-proportional and green data center approaches, while performance remains unaffected.
