Studies have shown that much of today’s data centers are over-provisioned and underutilized. Over-provisioning cannot be avoided as these centers must anticipate peak load with bursty behavior. Under-utilization, to date, has also been unavoidable as systems always had to be ready for that sudden burst of requests that loom just around the corner. Previous research has pointed to turning off systems as one solution, albeit, an infeasible one due to its irresponsiveness. In this paper, we present the feasibility of using new Storage Class Memory (SCM, Chaussures Lv which encompasses specific developments such as PCM, MRAM, or FeRAM) technology to turn systems on and off with minimum overhead. This feature is used to Louis Vuitton Chaussure Homme Mocassin control systems on the whole (in comparison to the previous fine-grained component-wise control) in finer time scale for high responsiveness with minimized power lost to idleness. Our empirical study is done by executing real trace-like workloads on a prototype data center of embedded systems deploying FeRAM. We quantify the energy savings and performance trade-off Louis Vuitton Ceinture Epi by turning idle systems off. We show that our energy savings approach consumes energy in proportion to user requests with configurable quality of service. Finally, based on observations made on this data center, we discuss the requirements for real deployment.
