 Energy Proportionality and Workload Consolidation for ...
processors [22, 45] provide a foundation for energy propor-tionality. The second goal is workload consolidation, which raises server utilization and minimizes the number of servers needed for a particular set of workloads [14, 46, 50]. Ad-vances in cluster management [11, 32] and server consoli-dation using virtual machines or container systems ......
The E ect of Server Energy Proportionality on Data Center ...
2.3. Server energy proportionality and metrics Energy proportional servers consume power proportional to their utilization. Power consumption of a server at di er-ent utilization levels can be represented as a power-utilization curve. An ideal energy proportional server will have a power-utilization curve as a straight line joining zero to peak ......
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.
[1501.02724] Towards Energy-Proportional Computing Using ...
Abstract: Massive data centers housing thousands of computing nodes have become commonplace in enterprise computing, and the power consumption of such data centers is growing at an unprecedented rate. Adding to the problem is the inability of the servers to exhibit energy proportionality, i.e., provide energy-efficient execution under all levels of utilization, which diminishes the overall ...

Choosing the Best Server for a Data Center: The Importance ...
quantify energy proportionality. An ideal energy proportional server would consume power in proportion to its utilization, that is, P(u) curve would be linear with P(0) = 0 (no power consumption when idle). Such a server will have constant energy efficiency throughout the utilization range. Energy proportionality has historically been measured ......
Energy proportional datacenter networks
tween common server workload profiles and server energy effi-ciency [3]. In particular, they show that a typical Google cluster spends most of its time within the 10-50% CPU utilization range, but that servers are inefficient at these levels. They therefore make the call for energy proportional computing systems that ideally con-...
NSF Award Search: Award#1815643 - SHF: Small: Energy ...
The research consists of three main thrusts: 1) development of heterogeneous benchmarks to evaluate server energy profile and metrics to quantify heterogeneous server energy proportionality in order to investigate the implications of virtualization and heterogeneous architectures, 2) development of software support for container live migration ......

Warehouse-Scale Computing: The Machinery That Runs the ...
WSCs are built of low-end or mid-range server-class computers connected in racks of 40 to 80 units by a first-level networking switch; each switch connects in turn to a cluster-level network fabric that ties together all of the racks. The clusters, which tend to be composed of several thousand servers, constitute the primary units of computing ...
