POWER MANAGEMENT FOR DATACENTER POWER ARCHITECTURES

摘要

A system for managing resource utilization associated with a system board comprising a plurality of processors, a memory associated with each processor, a plurality of voltage regulators configured to adjust voltages applied to the processors and memory, and a board manager configured to manage resources of the system board The resource management method includes a step of independently communicating operating condition information from the board manager to a controller of a voltage regulator, the processor communicating with the controller of the voltage regulator, wherein the operating condition information received by each controller is controlled by the controller Lt; RTI ID = 0.0 a / RTI voltage regulator. The method further includes the step of controlling the voltage regulator based on the operating condition information to set the power limit of the voltage regulator in accordance with the processing load indicated by the operating condition information transmitted to the controller related to each processor by the board manager do.
