Abstract

The invention provides a regulation and control method and system for a server fan and a server, and is used for regulating and controlling the fan when a BMC (Baseboard Management Controller) fails, and the regulation and control method comprises the following steps: a programmable logic device obtains a temperature sensor signal and a temperature alarm signal of a CPU (Central Processing Unit); based on the temperature sensor signal, the temperature alarm signal and the corresponding relation between the single board temperature and the fan PWM, the corresponding PWM duty ratio under the current signal is obtained; and the PWM duty ratio is controlled and output through the ratio of the current counting value of the counter to the counting period, and the rotating speed of the fan is adjusted. The temperature signals, collected by the sensor, of all the single boards of the server are obtained through the programmable device, flexible control over the PWM duty ratio is achieved by means of output of the timer in combination with the corresponding relation between the single board temperature and the PWM duty ratio, the reasonable fan rotating speed can be set based on the single board temperature when the BMC fails, and therefore the service life of the fan is prolonged. And the requirements of server heat dissipation and fan power consumption are considered.

Description

technical field [0001] The invention relates to the technical field of server heat dissipation, in particular to a server fan control method, system and server. Background technique [0002] Fans have been widely used in server systems and have basically become an integral part of server equipment. Server equipment will generate a lot of heat when it is working. In order to ensure the normal operation of the equipment, fans are very important for cooling the equipment. At the same time, the fan will also consume a large part of the power consumption when it is running. [0003] The failure of the BMC (Baseboard Management Controller, baseboard management controller) may occur when the server runs for a long time. Now when the BMC fails, a common way to deal with the fan is to keep the fan running at full speed. The result of this is that when the ambient temperature is not too high, the fan still maintains the highest speed, which consumes a lot of power consumption, resu...
