Data processing system having power capping function in response to output state of power supply module

摘要

A data processing system includes a plurality of power supply modules each having a comparing unit for comparing an output-current value supplied to a computer with a threshold value, the plurality of power supply modules continue the comparison when the output-current value is equal to or less than the threshold value and outputs an output-current excess signal to a plurality of server blades when the output-current value is equal to or greater than the threshold value, and the plurality of server blades control respectively power consumptions of the server blades to make a power consumption value of the server blades to an equal to or less than a predetermined value on a power source non-redundancy.

1. A data processing system comprising a plurality of server blades, a plurality of input power sources, a plurality of power supply modules configured to convert a power supplied from said plurality of input power sources into a voltage to output to said plurality of server blades, and a management module connected with said plurality of server blades and said plurality of power supply modules via buses,
wherein each of said plurality of power supply modules includes a power-source supply line connected electrically with said plurality of server blades and one of said plurality of input power sources, a current measurement unit configured to measure an output-current value supplied to said plurality of server blades on said power source supply line, and a comparing unit configured to compare said measured output current value with a predetermined threshold value, and wherein when the comparing unit of one power supply module of said plurality of power supply modules determines said output current value of said one power supply module is greater than said predetermined threshold value,
a signal notification unit of said one power supply module is configured to output an output-current excess signal to said plurality of server blades, andeach of said plurality of server blades is programmed to control a power consumption of said each server blade to an equal to or smaller than a predetermined power consumption value in response to said output-current excess signal.
