Abstract

The invention provides a fan speed regulating method and a fan speed regulating device for a rack-mounted server system. The method comprises the following steps: detecting a system temperature of therack-mounted server system, and simultaneously, detecting practical temperatures of various non-temperature sensitive components in the rack-mounted server system; according to the system temperature, determining a first duty ratio of a fan; according to the practical temperatures of the various non-temperature sensitive components, respectively determining the fan duty ratios corresponding to the various non-temperature sensitive components, and taking the maximum value of all fan duty ratios as a second duty ratio of the fan; and when the first duty ratio is greater than the second duty ratio, regulating the duty ratio fan of the fan according to the system temperature, and otherwise, regulating the duty ratio of the fan according to the practical temperatures of the non-temperature sensitive components corresponding to the second duty ratio. According to the fan speed regulating method and the fan speed regulating device for the rack-mounted server system, the control precision offan speed regulating can be improved, so that the fan speed regulating is more smooth and accurate.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a fan speed regulating method and device for a rack server system. Background technique [0002] In a rack server system, the quality of heat dissipation directly affects the performance and security of computing, and also affects the overall power consumption of the system. The traditional heat dissipation solution is to collect the temperature of the CPU or the air inlet. When the collected temperature reaches the set temperature value, the fan speeds up immediately; when the collected temperature value drops below the set temperature value, the fan starts to decelerate. [0003] In the process of realizing the present invention, the inventor found that there are at least the following technical problems in the prior art: [0004] The existing speed regulation method can only regulate speed for a limited number of temperature points, and the accuracy is insufficient.
