Problems solved by technology

[0003] In the existing technology, it is necessary to enter the linux system to obtain the information of the hard disk, and obtain it through certain commands. This method is very inconvenient. In the non-system interface, such as the BIOS interface, the temperature of the hard disk cannot be obtained at this time, which is inconvenient for users. Real-time monitoring of hard disk temperature
In addition, the existing fan speed adjustment is generally based on comprehensively adjusting the fan speed by referring to the temperature of the CPU, motherboard, backplane, and hard disk. An approximate temperature, not accurate, resulting in the inability to accurately adjust the fan speed

Abstract

The invention discloses a server fan speed control system and method. The server fan speed control system comprises a BMC, an SAS card connected with the BMC, a back board connected with the SAS card,a CPLD mounted on the back board, and hard disks connected with the back board; a PBSI module is arranged in the SAS card; the BMC is connected with the SAS card and the CPLD through I2C buses; the SAS card is connected with the back board through an SAS wire cable; and the hard disks are connected with the back board through an SATA or SAS interface. Compared with the prior art, the temperaturesof the hard disks can be monitored accurately in real time to adjust a fan speed.

Description

technical field [0001] The present invention relates to the technical field of server communication, in particular to a server fan speed control system and method. Background technique [0002] The existing method for obtaining the temperature of the hard disk is generally to obtain the smart information of the hard disk through the smartctl command under the system, including the temperature of the hard disk. Some of them are obtained under the system through the tools provided by the SAS card manufacturer (such as arcconf). The existing server adjusts the fan speed as a reference point for the temperature on the hard disk, which is generally obtained by a temperature sensor on the backplane closest to the hard disk, and uses this temperature as a reference for the hard disk temperature. [0003] In the existing technology, it is necessary to enter the linux system to obtain the information of the hard disk, and obtain it through certain commands. This method is very incon...
