Abstract

In order to solve the problems in the prior art, the invention innovatively provides a fan rotating speed regulation and control method for a server, which comprises the following steps that: a BMC (Baseboard Management Controller) acquires and calculates the added value of the output power of a power supply in first time; the BMC determines the interval where the added value is located accordingto the interval; the rotating speed of a fan is adjusted to a corresponding fan rotating speed value till the server is in a stable operation working state. The invention further provides a fan rotating speed regulation and control device for the server.. The problems that an existing fan regulation and control mode is single, and energy consumption is large are effectively solved. The fan regulation and control efficiency is effectively improved while energy cost is reduced. the temperature of the corresponding PCIE equipment is obtained through the BMC. According to the corresponding relationships between a PCIE area and fans, the corresponding fans are controlled to adjust the rotating speed, the heat dissipation efficiency and the utilization rate of the fans can be improved, the rotating speed of each fan is independently controlled, and resonance and high-frequency noise caused by the fact that the multiple fans operate at the same rotating speed can be avoided.

Description

technical field

[0001] The invention relates to the field of fan control, in particular to a method and device for controlling the rotational speed of a server fan. Background technique

[0002] With the rapid development of cloud computing and machine learning, the calculation and storage of data are increasingly relying on the data center. As the most critical component of the data center, maintaining good heat dissipation of the server in the case of high density has a great impact on the life of each component inside the server and Stability plays a key role. Due to the small internal space of the server, high component density, and under the condition that the existing water cooling method is not yet mature and stable, the accumulated heat inside the server can only be discharged by driving air through a high-power fan.

[0003] At present, a general-purpose 2U server has 4 or more fans of 20W or more. If it runs at full speed, the total power can reach more than 80W, ...
