SYSTEM AND METHOD FOR CONTROLLING ENERGY USAGE IN A SERVER

摘要

A system for controlling energy usage in a server having a processor, where the system includes a memory for storing energy cost information, and a controller for determining a transaction rate for the processor. The controller is also for determining a cumulative of energy expended by the server based on the determined transaction rate for each of a number of available power level states (P-states) for operation of the processor, and for selecting one of the available P-states for operation of the processor based on the determined cumulative energy expended and the stored energy cost information.

1. A system for controlling energy usage in a server comprising a processor, the system comprising:
a memory for storing energy cost information; and a controller for
determining a transaction rate for the processor,for each of a plurality of available power level states (P-states) for operation of the processor, determining a cumulative of energy expended by the server based on the determined transaction rate, andselecting one of the available P-states for operation of the processor based on the determined cumulative energy expended and the stored energy cost information.
