Computer and power management system for computer
The power consumption of a computer is dynamically managed independent of the OS or applications and without any delay time caused by system control. A blade server has server blades each including a processor, a power-saving control unit and a power sensor unit; a power supply box that supplies power to the server blades; and a single service processor which defines an electric current consumption upper limit value in the power sensor unit via the power-saving control unit of each server blade. When the electric current consumption of the server blades exceeds the electric current consumption upper limit value, a signal outputted by the power sensor unit is communicated to the processor, the operating frequency of the processor is controlled, and the maximum average power is controlled to be at or below the power consumption upper limit value.
