Low Power Mode in Cloud Storage Systems

The authors consider large scale, distributed storage systems with a redundancy mechanism; cloud storage being a prime example. They investigate how such systems can reduce their power consumption during low-utilization time intervals by operating in a low-power mode. In a low power mode, a subset of the disks or nodes are powered down, yet they ask that each data item remains accessible in the system; this is called full coverage. The objective is to incorporate this option into an existing system rather than redesign the system.
