The invention provides a power supply overload protective device and method of a server. The method includes the following steps that a first signal, a second signal and a third signal from a first power supply unit are received, and the first power supply unit provides power for a plurality of main boards arranged on the server; a first signal, a second signal and a third signal from a second power supply unit are received, and the second power supply unit provides power for the main boards; control signals are generated according to the first signal, the second signal and the third signal of the first power supply unit and the first signal, the second signal and the third signal of the second power supply unit; and the electric power consumption of the main boards is adjusted according to the control signals, so that the outage problem caused by electric power overload of the entire server system when a part of power supply devices break down in an existing sever with a plurality of power supply devices in prior art can be solved.
Description
technical field [0001] The invention relates to the field of servers, in particular to a server power supply overload protection device and method. Background technique [0002] In a server, there are multiple power supplies that provide power to multiple motherboards. If a part of the power supply fails, it will not be able to provide enough power to the motherboard, thus causing the power overload of the entire server system and causing a power outage. Therefore, a power supply overload protection device and method are needed to solve the above problems. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a server power supply overload protection device and method, which is used to solve the problem of failure of some power supplies in servers with multiple power supplies in the prior art. Sometimes it will cause the power overload of the entire server system and cause a pow...
