Server fan regulation and control method and system

Abstract

The invention relates to the technical field of servers, and provides a server fan regulation and control method and system. The method comprises the following steps that a parameter value of a sensorat an air inlet is acquired, and a current environment temperature parameter is acquired; a standard working temperature parameter matched with each electronic component is obtained according to thecurrent environment temperature parameter; a PWM variable quantity corresponding to each electronic component is calculated according to the corresponding standard working temperature parameter; the PWM variable quantities corresponding to all the electronic components are controlled to be traversed, and the maximum value in the PWM variable quantities is found and acquired; and the found and acquired maximum value of the PWM variable quantities is conveyed to a fan, and the fan is controlled to be adjusted by the rotating speed deviation matched with the maximum value in the PWM variable quantities so as to achieve the control of the rotating speed of the fan. And therefore, the working temperature of each electronic component is guaranteed to be within the required parameter range, moreover, the power consumption of a whole machine is also reduced, noise is reduced, the optimal working state of the machine is achieved, and power consumption is saved for users.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a server fan control method and system. Background technique [0002] With the development of new technologies such as cloud computing and big data, the bandwidth and capacity requirements of data storage are getting higher and higher, and the computing speed and amount of computing of processors are also increasing, resulting in the temperature of various components such as memory and hard disk. The heat dissipation of electronic devices has become a very hot issue at present, and the society's requirements for power consumption are getting lower and lower, and energy saving is a mainstream trend at present. How to effectively reduce the high temperature of each electronic component and reduce the power consumption of the fan wall, and satisfy the optimal power consumption of the whole machine is a technical problem that needs to be solved urgently.
