PERFORMANCE MANAGEMENT FOR DATA CENTER SERVICE ARCHITECTURES

摘要

A method of managing system resources that manages resource usage for a system board having multiple processors, memory associated with each of the processors, multiple voltage regulators configured to regulate voltages applied to the processors and memory, and a board manager configured thereto to manage resources of the system board includes communicating operating state information from the board manager to controller the voltage regulators independent of the processors that also communicate with the controllers, the operating state information received from each controller indicating a computational load for the processor other than that of the processor controlled by this controller controlled voltage regulator. The method further includes controlling the voltage regulators based on the operating state information to set the power limit of the voltage regulators according to the processing load indicated by the operating state information transmitted from the board manager to the controllers for each processor.
