Energy consumption is a growing issue in data centers, impacting their economic viability and their public image. In this paper, the authors empirically characterize the power and energy consumed by different types of servers. In particular, in order to understand the behavior of their energy and power consumption, they perform measurements in different servers. In each of them, they exhaustively measure the power consumed by the CPU, the disk, and the network interface under different configurations, identifying the optimal operational levels. One interesting conclusion of their study is that the curve that defines the minimal CPU power as a function of the load is neither linear nor purely convex as has been previously assumed.
