Tooling to improve data center efficiency

This survey paper investigates research relating to the opportunity to develop new tools to increase data center efficiency. We review techniques to improve data center efficiency, as well as the availability of research tools to achieve that goal. The techniques and tools discussed focus on reduced server utilization (power proportional), and reduced infrastructure power through air flow and free air cooling (green computing). In addition, some comprehensive research tools address both areas. We consider which methods may be appropriate for smaller data centers.
