Fan control method and device of server and server

Abstract

The invention provides a fan control method and a fan control device of a server and the server, wherein the server comprises a plurality of feature components and a plurality of fans. The method comprises the following steps: measuring temperature information and power consumption information of the plurality of feature components of the server; obtaining a current work mode of the server according to the temperature information and the power consumption information of the plurality of feature components; obtaining temperature of a plurality of key positions in the server according to the current work mode of the server and the preset temperature prediction model; respectively controlling the plurality of fans according to the temperature of the plurality of key positions. By adopting the method disclosed by the embodiment of the invention, real-time prediction of the temperature of the plurality of key positions is achieved in a numerical simulation manner under the premise of not increasing a physical sensor to the server; the plurality of fans are respectively controlled according to the real-time prediction temperature; the reliability of real-time measurement of temperature of the server is improved; the potential safety hazard in the server is reduced; meanwhile, the fans of the server are accurately controlled, and the waste of power consumption of the fans is avoided.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to a server fan control method, device and server. Background technique [0002] At present, through the physical temperature sensor arranged in the middle of the server, the temperature information of a limited number of characteristic components in the server can be read, for example, CPU (Central Processing Unit, central processing unit), PCH ((Platform Controller Hub, platform control center) etc. The server thermal management control strategy is to use the temperature information read by the physical temperature sensor as a control parameter for the power consumption of the fan and characteristic components in the server, and to ensure the power consumption of the server by increasing or reducing the fan speed or controlling the power consumption of the characteristic components The temperature of the characteristic components of the server is within the limits of its d...

AI Technical Summary

Problems solved by technology

[0003] However, the current problems are: 1), the temperature information of all characteristic components cannot be captured, such as hard disk, memory, etc.

However, in fact, if the server is actually in an idle state, the fan speed does not need to be so high, which will inevitably cause waste of fan power consumption.

[0004] 2) Since the temperature information of the characteristic components in the server is also affected by many factors such as ambient temperature, system air flow, power consumption during heating, etc., it is difficult to capture enough and accurate temperature information, and also It is difficult to obtain accurate wind flow information, so the reliability of the predicted real-time temperature in the server is also very poor, and the purpose of precise control of the fan cannot be achieved.
