How Intel Power Management Works
Today's standards based servers offer the capability to allow the operator to actually set power consumption and trade off the power consumption level against performance. This capability is valuable, first, power capping brings predictable power consumption within the specified power capping range, and second, servers implementing power capping offer actual power readouts as a bonus. With actual historical power data, it is possible to optimize the loading of power limited racks, whereas before the most accurate estimation of power consumption had to be derived from derated nameplate data. This article explains how power consumption can be altered in significant ways through the integration with Intel Data Center Manager.
