Embodiment Construction

[0031] figure 1 is a schematic diagram of a server system according to an embodiment of the present invention. see figure 1 , the server system 100 includes a power supply module 110, a central management bus (Center Management Bus, CMB) 120, a plurality of motherboards 150 (wherein the component symbol 150 is represented as a collection of symbols 151, 152, 153, . . . , 15z) , the hard disk module 140 and the fan module 130 . Wherein, the user can set whether the motherboards 151 , 152 , 153 , . . . , 15z are powered on according to requirements.

[0032] The power supply module 220 receives AC power and outputs DC power after AC / DC conversion, and the DC power represents the total output power of the server system 100 . The central management bus 120 includes a control module 122 , and the central management bus 120 is electrically coupled to the power supply module 110 , the motherboards 151 - 15z , the hard disk module 140 and the fan module 130 . The power output by t...

Abstract

The invention relates to a power supply distribution method and a server system applying the power supply distribution method. The power supply distribution method is appropriate for the server system. The method comprises the following steps of: first, respectively supplying average power to a started mainboard and respectively reading expected power of the started mainboard, and comparing the expected power with the average power, wherein if the expected power is greater than the average power, a first state is defined, and if the expected power is smaller than the average power, a second state is defined; then, calculating the expected power and the average power of the mainboard defined in the second state, and obtaining a first residual power supply; and then, averagely distributing the first residual power supply to the mainboard defined in the first state. The method can be used to dynamically distributed the power supply according to demands of the mainboards and provide power required by operation of the mainboard.

Description

technical field [0001] The invention relates to a power management technology, in particular to a power distribution method applied to a server system. Background technique [0002] Generally speaking, static power capping is adopted for the power management of the server, so as to evenly distribute fixed power to each motherboard. However, when the server is running, the power required by each motherboard is different. Some motherboards expect less than the fixed wattage, and some expect more than the fixed wattage. Therefore, the prior art cannot effectively distribute power to motherboards with different loads. In motherboards whose expected power is lower than the fixed power, the motherboard is assigned too high a power capping value; and in motherboards whose expected power is higher than the fixed power, the motherboard is assigned too little power capping value. electric control value. That is to say, the current fixed power consumption control technology does no...
