DATA CENTER POWER ADJUSTMENT

摘要

A power cap agent establishes a power cap. The power cap agent throttles a first power priority virtual machine. The power cap agent determines that the first power priority virtual machine and the additional power priority virtual machine contribute to power consumption above the power cap among the plurality of servers. The power cap agent throttles the additional power priority virtual machine, wherein the first power priority virtual machine has a first power priority lower than an additional power priority of the additional power priority virtual machine. The power cap agent determines that the first power priority virtual machine and the additional power priority virtual machine contribute to power consumption above the power cap, responsive to throttling the first power priority virtual machine and throttling the additional virtual machine.
