Problems solved by technology

[0003] The current server fan control system is mainly divided into two types, one is the BMC (Baseboard Management Controller, baseboard management controller) direct control method, all detection and control functions in the fan control system are realized by the BMC, once the BMC fails, the entire fan control system will be out of control; the other is BMC + external control chip method, although this control method is more stable than the BMC direct control method, but it increases the design cost and PCB (Printed Circuit Board, printed circuit board) wiring complexity

Abstract

The invention discloses a method for controlling a fan of a server. The method comprises the following steps executed by a CPLD of detecting whether a watchdog signal output by a BMC is normal or not,and performing reset operation on the BMC in response to the detected normal watchdog signal; detecting whether the fan is in place one by one, and detecting PWM control signals from the BMC; outputting a power supply enabling signal in response to the detected PWM control signals from the BMC, controlling the rotating speed of the in-place fan according to the PWM control signal; and outputtinga power supply enabling signal in response to the not detected PWM control signals from the BMC, controlling the rotating speed of the in-place fan according to a preset control signal. The inventionfurther discloses a device for controlling the fan of the server. According to the method and the device for controlling the fan of the server, the wiring complexity of the PCB of the server can be remarkably reduced, the design structure is simplified, and the design cost of the system is reduced.

Description

technical field [0001] The present invention relates to the field of servers, and more specifically, to a method and device for controlling a fan of a server. Background technique [0002] With the continuous improvement of server performance, the power consumption of server equipment increases accordingly, and the calorific value of server equipment is increasing accordingly. Therefore, the design requirements for fan control systems are also continuously improving. Server fan The stability of the control system has become a key factor for the stable and reliable operation of the server system. [0003] The current server fan control system is mainly divided into two types, one is the BMC (Baseboard Management Controller, baseboard management controller) direct control method, all detection and control functions in the fan control system are realized by the BMC, once the BMC fails, the entire fan control system will be out of control; the other is the BMC+external control ...
