 The Case for Energy-Proportional Computing
Energy-proportional designs would enable large energy savings in servers,potentially doubling their efficiency in real-life use.Achieving energy proportionality will require significant improvements in the energy usage profile of every system component, particularly the memory and disk subsystems.

Reducing Cluster Energy Consumption through Workload ...
Energy consumption is a major and costly problem in data centers. For many workloads, a large fraction of energy goes to powering idle machines that are not doing any useful work. There are two causes of this inefficiency: low server utilization and a lack of power proportionality. We focus on addressing this problem for two workloads: (1) a traditional, front-end web server workload and (2 ......

We deployed Hypnos on a 57-server production cluster. From a 21-day run, we obtained a 36% energy saving in spite of multiple server and network failures.

Measuring Server Energy Proportionality
achieving the greatest energy proportionality at cluster level. Since none of existing linearity metrics provides this kind of insight, the paper calls for the development of a good lin-earity metric in the context of energy proportionality. The rest of the paper is organized as follows. Section 2 provides information on how trends in server ......

2.2 Energy Proportionality Energy proportional computing [4] is an important concept in today’s server systems. It aims to address the increasing energy concern and demand for power saving by making servers consume energy proportional to its workload. This goal is normally achieved by conditionally trading off performance for power savings....
Metrics, Models and Methodologies for Energy-Proportional ...
Adding to the problem is the inability of the servers to exhibit energy proportionality which diminishes the overall energy efficiency of the data center. Therefore in this dissertation, we investigate whether it is possible to achieve energy proportionality at the server- and cluster-level by efficient power and resource provisioning....

Measuring Energy Consumption of a Database Cluster
To avoid the limitations of a single large server in achieving energy proportionality, we are going to propose a new approach by employing commodity hardware to form an energy-proportional computing cluster. Small-scale server nodes (aka. wimpy nodes [AFK+09]) can be independently turned on and off, thus providing better scalability in terms of ......
