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.

Computer system fans having fixed operating states corresponding to discreet operating speeds may be controlled by collecting temperature information upstream or downstream of the fans and commanding the fans to switch between the fixed operating states based on the temperature information at a frequency sufficient to controllably achieve speeds between the discreet operating speeds.

The disclosed embodiments provide a system that analyzes telemetry data from a computer system. During operation, the system obtains the telemetry data as a set of telemetric signals using a set of sensors in the computer system. Next, the system analyzes the telemetry data to estimate a value of a parameter associated with the computer system, wherein the parameter is at least one of a power utilization and a temperature. Finally, the system controls a subsequent value of the parameter by modulating a virtual duty cycle of a processor in the computer system based on the estimated value.
