Methods for power management in a computer system with multiple processing resources and multiple power supplies
First Claim
1. A method for power management in a computer system including multiple processors and multiple power supplies operable to supply power to the multiple processors, the method comprising:
- receiving a notification of a pending change in an operating status of one or more of the multiple processors at a power management engine; and
in response to the received notification;
accessing, by the power management engine, a dynamic table listing historical power-related data regarding the one or more of the multiple processors having the pending change in the operating status;
determining an adjustment of the one or more of the multiple power supplies by the power management engine based at least on the accessed historical power-related data regarding the one or more of the multiple processors; and
adjusting one or more of the multiple power supplies by the power management engine before the pending change in the operating status of the one or more of the multiple processors is implemented.

Abstract
A system and method are provided for strategic power supply sequencing in a computer system. The system and method includes a plurality of processing resources that process data and a plurality of power supplies that provide power for the processing resources. A power management engine adjusts the power supplies in response to processing resource changes to optimize power consumption. The power management engine brings online power supplies to meet the demand created by bringing online additional processing resources and brings offline power supplies to meet the decreased demand caused by a decrease in the number of processing resources. Also, the power management engine rotates which power supplies operate to take advantage of more efficient power supplies and to extend the lives of the power supplies. The power management engine also adjusts the power supplies in advance based upon predicted demand levels for the computer system.
