METHOD, SYSTEM AND PROGRAM FOR POWER MANAGEMENT OF ELECTRONIC SYSTEM (POWER MANAGEMENT OF ELECTRONIC SYSTEM)

摘要

PROBLEM TO BE SOLVED: To provide an improved power management technique for better utilizing power available to a system and maximizing throughput on servers.

SOLUTION: A variable group power limit is enforced to limit the net power consumption of a group of devices in a computer system. A variable device power limit enforced on each device is independently adjustable to satisfy the current group power limit. The device power limits are dynamically selected according to a power management method that selectively reduces the device power limits of lower utilization devices and increases the device power limits of higher utilization devices.
