US Patent 7783907 Power management of multi-processor servers

A method and system are provided for dynamically managing delivery of power to partitionable elements in a computer system while supporting terms of a Service Level Agreement (SLA). Parameters of the SLA are gathered in conjunction with the topology of the computer system. Transactions associated with the SLA are monitored and high and low usage periods are predicted based upon a history of transactions. Power to partitionable elements of the computer system may be adjusted during high and low usage periods. In addition, dynamic management of the partitionable elements is provided in response to current demands. Management of the partitionable elements is all made in compliance with the SLA.
