Server power supply cold redundancy control method and device based on BMC and BMC

Abstract

The invention discloses a server power supply cold redundancy control method and device based on a BMC, the BMC and a server. The method comprises the steps that the BMC detects state information of Npower supplies for supplying power to the server; when it is detected that an alarm event or an in-place loss event exists in the M power supplies, a CPU throttling protection Pin is controlled to trigger a CPU in the server to reduce the frequency; the CPU or the system node management controller is controlled to limit the whole machine system power consumption of the server not to exceed a preset power consumption value; in the invention, the BMC controls the CPU throttling protection Pin to trigger the CPU to reduce the frequency and rapidly reduce the power consumption of the whole machine system, thereby avoiding the overload of the power consumption of the system caused by abnormal output of a redundant power supply; and the power consumption of the whole system is limited not to exceed the preset power consumption value through the control CPU or the system node management controller, so that the control of the cold redundancy of the server power supply is realized, the specification requirement of a client on the cold redundancy of the power supply in the high-configuration server application is met, and the power supply design complexity and the power supply cost are reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a BMC-based server power supply cold redundancy control method, device, BMC and server. Background technique [0002] With the development of science and technology in modern society, the application of servers is becoming more and more extensive. With the enhancement of the processing capability of the processor (CPU, such as X86 processor) in the server, the power of the processor continues to increase. The power consumption of the server system is getting higher and higher, and the increase speed of the single power supply of the server cannot keep up with the increase speed of the server system, resulting in a single power supply that cannot meet the power supply requirements of the server system, especially the four sub-stars, etc. A multi-node server system has higher requirements for power supply, and must use dual power supplies or more power supplies.

Problems solved by technology

This has resulted in the inability to meet the requirements of customer (user) requirements and specifications, affecting market sales, especially in the process of customer application, the damage or abnormality of a power supply often causes the entire server business system to be powered off, affecting customer business operations, resulting in customer business failures. loss
