Problems solved by technology

In order to deal with the heat dissipation problem of Raid/SAS storage boards, manufacturers integrate temperature sensors in the control chips of storage boards to monitor the status. The temperature sensor information can theoretically be obtained by the BMC management chip and used to control the system fan speed. approach increases the design cost of the memory board
However, the existing fan control scheme does not specify the board configuration information, and does not obtain the temperature of

Embodiment 1

[0026] Such as figure 1 As shown, the fan control method for improving server noise of the present invention adds a switch chip on the motherboard, the switch chip is connected to the BMC through the I2C bus to increase the number of I2C addresses allocated by the BMC, the switch chip is connected to the PCIE slot of the motherboard, and the Different I2C addresses are assigned to different PCIE slots to ensure that the I2C addresses of all PCIE slots on the motherboard do not conflict, and the monitoring of all boards is realized through independent I2C addresses. The board feature code is integrated in the BIOS of the motherboard, and the board type is identified through the board feature code. The BIOS reads the board type information and sends the board type information to the BMC. The BMC counts the number of boards and PCIE slot information based on the assigned I2C address to determine whether there is a storage board. If there is a storage board, start the storage boa...

Embodiment 2

[0028] Such as figure 2 As shown, the fan control system for improving server noise of the present invention includes: a BMC module, a fan control unit, a storage board temperature control unit, a switch chip, a PCIE slot, a BIOS module and a system fan. The fan control unit is set in the BMC module and integrates fan control strategies for different configurations. The storage card temperature regulation unit is integrated on the fan control unit. The BMC module is connected to the switch chip through the I2C bus, and the number of I2C addresses is increased through the switch chip to ensure that the I2C addresses of all PCIE slots do not conflict. Type of the board in the PCIE slot. The switch chip is connected to the PCIE slot, the BIOS module is connected to the PCIE slot and the BMC module respectively, and the BMC module is connected to the system fan. The board feature code is integrated in the BIOS module. The BIOS module is connected to the PCIE slot. The board typ...

Abstract

The invention discloses a fan control method and system for improving noises f a server, and belongs to the technical field of heat dissipation of servers. According to the fan control method for improving the noises of the server, a switch chip is added on a mainboard to increase the number of BMC distributed I2C addresses, different I2C addresses are distributed to different PCIE trenches, and the I2C addresses of all the PCIE trenches do not interfere; the BIOS of the mainboard recognizes types of board cards in the PCIE trenches and transmits information of the types of the board cards to a BMC; fan control strategies configured for the different board cards are integrated in the BMC; and the BMC calls the fan control strategies which are configured correspondingly according to the number of the recognized board cards and the information of the PCIE trenches. By the fan control method and system for improving the noises of the server, the problem of heat dissipation of the server can be avoided effectively, the noises of the whole server can be reduced by above 10 dB, and the popularization and application value are quite high.

Description

technical field [0001] The invention relates to the technical field of server heat dissipation, and specifically provides a fan control method and system for improving server noise. Background technique [0002] Compared with traditional computers, servers have better scalability, ease of use, and ease of management, and are widely used by large enterprises. With the further development of the economy and business needs, users have higher and higher requirements for the performance of the server, the corresponding server specifications are gradually improved, and the number of PCIE slots designed for the server motherboard is increased, corresponding to the boards that can be carried by the whole server system. The number and types of cards increase, and there are different configurations. Various boards will generate heat during work. To ensure the normal operation of the server, the generated heat should be discharged in time. Fans play an important role, and different bo...
