Method, device and system of server fan speed regulation

Abstract

The invention provides a method, device and a system of server fan speed regulation.The method comprising the following steps that parameters of server fan speed regulation of a server is acquired andinitialized; a test is started, and the log data of the speed regulation control of a fan is acquired and storedaccording to a preset time interval; according to the log data, the rotation speed change of the fan and the temperature change of acontrolled device on the server are calculated; and according to the rotation speed change of the fan, if the temperature change of the controlled device isdetected to be larger than atarget threshold value, the data values corresponding to the parameters are adjusted according to the sensitivity, the log data and the parameters output in the last timeuntil the temperature change of the controlled device is smaller than or equal to the target threshold value. The problem that a traditional PID setting process depends on experience is solved, automatic analysis and high-efficiency treatment of PID fan speed regulation are realized, and the setting process is present in informational and graphical modes, the visual performance of thePID fan speedregulation setting is improved, so that the setting efficiency is improved, the method, the device and the system can be adapted to different servers, and havewide usability.

Description

technical field [0001] The invention relates to the technical field of computer heat dissipation equipment, in particular to a method, device and system for adjusting the speed of a server fan. Background technique [0002] With the development of computer technology, due to the limited size of the server, many high-power electronic components run in it for a long time and under high load. Whether the heat generated can be transferred to the outside in a timely manner directly affects the stability of the server operation. Therefore, passive cooling GPUs and MIC cards in high-performance computing servers have higher and higher cooling requirements. [0003] The heat dissipation technology of the server includes air cooling, liquid cooling, heat transfer and so on. Fans are commonly used for air cooling. The server relies on the fan to generate airflow (circulation) in the chassis to take away the heat of the heat-generating components (such as CPU, memory, hard disk, etc....

AI Technical Summary

Problems solved by technology

However, when the temperature of the main board of the server changes suddenly, the speed of the fan cannot respond quickly; in addition, artificially analyzing the log data of the fan control is prone to errors due to the huge amount of log data, and the control of the PID in the server mainly depends on experience, resulting in the setting low efficiency
