Embodiment Construction

[0044] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Hereinafter, the power management of each server blade mounted in the blade server will be mainly described. However, the present invention is not limited to blade servers, but is also applicable to power management of other computers such as PC servers operating alone.

[0045] figure 1 It is a schematic diagram showing the overall configuration of the blade server. In the blade server, a plurality of server blades 101 are installed in one chassis 100 and connected to one service processor 102 via a backplane connected to the back of the server blades 101 . A plurality of power supply boxes 103 and cooling fans 104 are disposed behind the chassis. The service processor 102 detects the temperature inside the chassis via the backplane, and controls the rotation speed of the cooling fan 104 . The power box 103 supplies power to the server blade 101, the service processo...

Abstract

The power consumption of a computer is dynamically managed independent of the OS or applications and without any delay time caused by system control. With respect to a blade server comprising, within one chassis: server blades 101 each comprising a processor 203, a power-saving control unit 201 and a power sensor unit 200; a power supply box 103 that supplies power to the server blades; and a single service processor 102, the service processor 102 defines an electric current consumption upper limit value in the power sensor unit 200 via the power-saving control unit 201 of each server blade. When the electric current consumption of the server blades exceeds the electric current consumption upper limit value, a signal 207 outputted by the power sensor unit 200 is communicated to the processor 205, the operating frequency of the processor is controlled, and the maximum average power is so controlled as to be at or below the power consumption upper limit value.

Description

technical field [0001] The present invention relates to a power management technology for managing the power consumption of each server blade incorporated in a computer, for example, a PC server or a blade server. Background technique [0002] The so-called blade server refers to a system board (system board) obtained by mounting a processor, memory, I / O, etc. on a motherboard (mother board) at high density. In addition, the so-called blade server refers to storing multiple server blades in one chassis, and sharing the chassis, power supply, fan, cables, etc., thereby achieving space saving while maintaining the basic functions as a PC server. A server system that reduces the total cost of introduction and management. In addition, such definitions are also applicable to the present invention. [0003] Since each server blade of the blade server has basic performance as a PC server, it is possible to operate different OS and applications for each server blade. As a power m...
