Abstract

We propose a new energy-aware data retrieval scheme (EDR) for mirrored video servers. We start by analytically determining the retrieval period that balances bandwidth and buffer size. We then propose a data retrieval scheme in which the period can be dynamically changed to reflect server utilization, with the aim of giving disks more chance to enter low-power mode. Simulation results show that it saves up to 36% energy compared with conventional video server operation.
