Abstract:
1. In a control box including at least one power supply and a control module having a power on management procedure and a power consumption estimation procedure, a method of managing power of the control box which, when powered on, causes the control module to perform the steps of: (a) running the power on management procedure to set a power on mode of each of a plurality of blade severs installed in the control box; (b) measuring power consumed by the blade servers running in the power on mode; (c) measuring power of the power supply; (d) running the power consumption estimation procedure to determine whether the power of the power supply is larger than the power consumed by the blade servers, and (e) determining whether a subsequent action should be continued by the control module based on the estimation; wherein the power consumption of each blade server in a full speed mode is S the power consumption of each blade server in the standby mode is S the number of each of the blade servers in the control box is M the number of each of the blade servers in the full speed mode is m the number of each of the blade servers in the standby mode is M the number of the power supply is C the number of the backup power supply is C the power of each of the power supply is P the power of each of the backup power supply is P the power consumption of the control module is E after the control box has finished the power on so that an equation approximately calculating the power consumption in the power on is:
