Problems solved by technology

However, in the fan control scheme of the server in the prior art, the configuration information of the server boards is not specified, and the fan control cannot be performed according to the number and type of the boards, and the temperature of the storage boards that dissipate more heat cannot be obtained. The actual temperature is used to control the fan. In this case, in order to meet the heat dissipation requirements of the server system, the fan control needs to be designed according to the worst working condition, which will cause the fan to consume extra power during the working process and cause the noise of the server system to increase by more than 10dB.
In addition, in this case, when there is a problem with the heat dissipation of storage boards such as raid cards, the server cannot automatically increase the fan speed to avoid heat dissipation risks, and further improvement is needed to ensure the normal operation of the server

Embodiment 1

[0030] According to the server fan control method for different types of board configurations in the present invention, for the server fan control method for different types of board configurations, fan control programs for different types of board configurations are integrated in the BMC. Different control temperature points and fan speed; establish a communication connection between BMC and BIOS to realize intelligent identification of the working status of different types of boards. Different fan control programs start different heat dissipation control methods to complete the control of the fan's working status.

Embodiment 2

[0032] like figure 1 As shown, on the basis of embodiment 1, the method described in this embodiment specifically includes the following steps:

[0033] S1: Read the relevant information of the board and conduct statistical analysis of the type and quantity of the board.

[0034] S2: Determine the number of boards. When the number of boards is zero, call the control program without boards. When there are boards, execute step S3.

[0035] S3: Determining whether there is a storage type board by board type, if not, execute step S4, and if yes, execute step S5.

[0036] S4: call the common board control program, and calculate the fan speed according to the air inlet temperature and the main board sensor;

[0037] S5: Call the storage board control program, start the storage board temperature reading program, determine whether the number of read temperature values ​​is consistent with the number of storage boards, if they are consistent, execute step S6, otherwise execute step S...

Embodiment 3

[0042] The server fan control system for different types of board configurations includes: Board information reading module: used to read the relevant information of the board.

[0043] Board information analysis module: used to analyze the number and type of boards.

[0044] Module for determining the number of boards: used to determine the number of boards, thereby invoking different fan control programs. When the number of boards is zero, call the control program without boards to control the fan speed; when there are boards, start the board type judgment module to judge the board type.

[0045] Board type determination module: used to determine the type of the board, so as to call different fan control programs. When the board type is a normal board, the fan speed is calculated according to the air inlet temperature and the motherboard sensor; when the board type is a storage board, start the storage board temperature reading program to determine the number of read temper...

Abstract

The invention discloses a server fan control method and system based on configuration of different types of board cards and belongs to the technical field of server cooling technologies. According to the server fan control method and system based on configuration of different types of the board cards, fan control programs for configuration of different types of the board cards are integrated in a BMC, and the different fan control programs correspond to different control temperature points and fan rotation speeds; and communication connection of the BMC and a BIOS is built, related information of the board cards in the BIOS is obtained by the BMC, and the different fan control programs are automatically called according to the related information of the board cards collected by the BMC, so that different cooling control manners are enabled, and the control over the working state of a fan is completed. According to the server fan control method and system based on the configuration of different types of the board cards, the rotation speed of the fan can be optimized, the cooling performance of a server is guaranteed, the noise of the server can be lowered effectively, and the server fan control method and system have the good application and popularization value.

Description

technical field [0001] The invention relates to the technical field of server heat dissipation, and specifically provides a server fan control method and system for different types of board configurations. Background technique [0002] Computers have the advantages of storing a large amount of information, and users can obtain information conveniently and quickly. They play an important role in today's society. Especially with the progress of society and economic development, the role of computers in people's lives has further increased. Compared with traditional computers, servers have better scalability, ease of use, and ease of management, and servers are more and more widely used in large enterprises. Especially with the expansion of enterprise scale and service scope, the performance requirements of the server are getting higher and higher, which leads to the gradual improvement of server specifications and the increase of the number of PCIE slots designed for the mothe...
