Patent ID: 7992011

Claim:
A power management method for an information platform including: at least one processing module; a management module; a switch for coupled to the processing module and the management module; and a power supply module for supplying power to the processing module, the management module, and the switch, the information platform causing at least one logical system constituted by the processing module to operate, the method comprising: a first step of holding, by the management module, system configuration information indicating a correspondence between the logical system and the at least one processing module constituting the logical system; a second step of holding, by the management module, power management information indicating a correspondence among information with which a type of the logical system can be specified, an operating condition of the logical system, and first power consumption which is power consumption for operating the logical system; a third step of selecting, by the management module, the processing module which constitutes the new logical system specified by a configuration request of the logical system by referring to the system configuration information when receiving the configuration request; a fourth step of calculating, by the management module, the first power consumption for operating the new logical system based on the type of the new logical system and the operating condition of the new logical system included in the configuration request, and the power management information; and a fifth step of determining, by the management module, second power consumption to be supplied to the processing module constituting the new logical system, so that a total of all the second power consumption to be supplied to all the processing modules constituting the new logical system is less than or equal to the first power consumption for operating the new logical system, in a case where the first power consumption for operating the new logical system is less than a total of maximum power consumption to be supplied to all the processing modules constituting the new logical system.
