Energy consumption has become an important issue in high-end data centers, and disk arrays are one of the largest energy consumers within them. Although several attempts have been made to improve disk array energy management, the existing solutions either provide little energy savings or significantly degrade performance for data center workloads. The solution, Hibernator, is a disk array energy management system that provides improved energy savings while meeting performance goals. This paper describes the Hibernator design, and presents evaluations of it using both trace-driven simulations and a hybrid system comprised of a real DataBase server (IBM DB2) and an emulated storage server with multi-speed disks.
