Embodiment 1

[0035] Such as Figure 2-Figure 3 As shown, the present invention provides a server fan speed control method, including:

[0036] S1, the BMC obtains and calculates the increase value of the output power of the power supply in the first time;

[0037] S2, corresponding the increase value of the output power of the power supply in the first time to several intervals, each interval corresponds to a fan speed value, and the BMC adjusts the fan speed to the corresponding fan speed according to which interval the increase value is located in value until the server is in a stable working state.

[0038] In step S1, the way of obtaining the output power of the power supply may be through the BMC through the SMBUS bus (system management bus). The first time may be a multiple of 3, such as 3, 6, 9, 12, 15, 18, etc., preferably 15s.

[0039] In step S2, the number of intervals is the same as the number of fan speed values, the initial value of the minimum interval among several inter...

Embodiment 2

[0043] Such as Figure 4-Figure 6 As shown, the technical solution of the present invention also provides a server fan speed control method, including:

[0044] S1, the BMC obtains and calculates the increase value of the output power of the power supply in the first time;

[0045] S2, corresponding the increase value of the output power of the power supply in the first time to several intervals, each interval corresponds to a fan speed value, and the BMC adjusts the fan speed to the corresponding fan speed according to which interval the increase value is located in value until the server is in a stable working state;

[0046] S3, when the server is in a stable working state, the BMC adjusts the fan speed according to the temperature of the PCIE device.

[0047] Among them, such as Figure 5 As shown, in step S3, according to the temperature of the PCIE device, the BMC adjusts the fan speed specifically including:

[0048] S31. Divide the PCIE device into several PCIE areas...

Embodiment 3

[0056] Such as Figure 7 As shown, the technical solution of the present invention also provides a server fan speed control device, including:

[0057] Obtaining module 101, BMC acquires and calculates the increase value of the output power of the power supply in the first time;

[0058] The first adjustment module 102 corresponds the increase value of the output power of the power supply in the first time to several intervals, each interval corresponds to a fan speed value, and the BMC adjusts the fan speed according to which interval the increase value is located in. The corresponding fan speed value until the server is in a stable working state.

[0059] The invention effectively solves the problem of single mode and large energy consumption due to the existing fan control, effectively improves the efficiency of fan control, and reduces energy consumption costs.

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, ...
