Abstract

The invention provides a speed regulation method and device for a server fan and a 64-CPU server. The method comprises the steps that the last temperature, the current temperature and the set temperature of a target object and the current duty ratio of the corresponding target fan are firstly determined, the duty ratio is calculated and regulated on this basis, and therefore a corresponding new duty ratio is determined; and then the rotating speed of the target fan is regulated according to the determined new duty ratio, the process circulates in this manner, and therefore real-time and accurate regulation of the rotating speed of the fan based on temperature changes of the target object is achieved. Thus, according to the scheme, the speed regulation stability of the server fan can be improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a server fan speed regulation method and device and a 64-way server. Background technique [0002] With the rapid development of information technology, high-end servers have significant advantages such as high reliability and high real-time performance compared with traditional servers, so they are more and more used in many high-demand key technical fields. Since some high-end servers, such as 64-way servers, may experience system instability caused by sensor temperature changes, it is necessary to adjust the speed of the corresponding fans in the server to alleviate or eliminate the instability. [0003] At present, it is possible to adjust the speed of the server fan by determining relevant linear parameters and adopting a linear adjustment method. [0004] However, because the existing speed regulation method is based on linear regulation, the stability of server fan spee...
