ABSTRACT:
An object of the present invention is to provide a management technique for managing power supply modules. In multiple computer equipment100, in response to a load state, if an operation system1101issues a command that changes a processor state of a processor1021to a sleep state, a management module107is notified through a management network MI that the processor state has changed. The management module107holds a system information108, and performs the steps of: updating system information108because the processor state has changed; from this system information108, calculating the power consumption required for the multiple computer equipment100; determining the number of required AC-DC power supply modules1061, 1062, . . . to be operated; and changing the number of operating AC-DC power supply modules1061, 1062, . . . by use of a control interface PA.
