 WattDB—a Rocky Road to Energy Proportionality
Current hardware is not energy proportional, because a single server consumes, even when idle, a substantial frac-tion of its peak power [1]. Because typical usage patterns lead to a server utilization far less than its maximum, en-ergy e ciency of a server aside from peak performance is reduced [4]. In order to achieve energy proportionality ......

•Cluster-wide EP reflects underlying server’s EP •If server’s EP is poor, then cluster’s EP is poor Packing Scheduling •Have exact number of servers for load •Cluster’s EP is ideal 7 [2] D.

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 ......
