Energy accounts for a significant fraction of the operational costs of a data center, and data center operators are increasingly interested in moving toward low-power designs. Two distinct approaches have emerged toward achieving this end: the power-proportional 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 equipment. We propose an integrated approach, which combines the benefits of both. 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.
