Method for reducing start-up noises of server system

Abstract

The invention discloses a method for reducing start-up noises of a server system, which belongs to a server static starting method. The method adopts a PWM speed regulating device to control the fan rotating speed in the start-up process of the server system so as to reduce the start-up noises of the server system, wherein the PWM speed regulating device comprises a power module, a pulse generation module, a switching module and a control module; the power module supplies electricity to the pulse generation module, the switching module and the control module; a PWM signal on a mainboard of the server system is input to the switching module and the control module; a PWM signal generated by the pulse generation module is input to the switching module; the switching module selectively outputs the PWM signal on the mainboard or the pulse generation module according to a switching control signal of the control module; and the PWM signal control the fan rotating speed. Compared with the prior art, the method for reducing the start-up noises of the server system can reduce the start-up noises of a server to ensure that the server is started quietly and does not limit the fan rotating speed when the system is in heavy duty service.

Description

technical field [0001] The invention relates to a method for silently starting a server, in particular to a method for reducing the starting noise of a server system. Background technique [0002] With the continuous development and progress of society, the concept of health and environmental protection is becoming more and more popular, which leads to people's higher and higher requirements on the noise of living and working environments. This appeal is also reflected in IT equipment such as servers. Therefore, it is imperative and imminent to reduce server noise. Major server manufacturers have put in a lot of effort to this end. While actively improving server noise, they have also proposed some practical noise reduction strategies, such as temperature control and noise reduction measures. That is, BIOS speed control technology. This technique mainly takes into account the fact that the server is not always running under high load. Therefore, let the fan run at a low sp...

Problems solved by technology

[0005] The noise reduction device for the boot fan currently used on PCs can play a role in noise reduction when the boot is started, but its biggest problem is that when the system is under high load, it will directly limit the fan speed (the fan is running at a low speed), causing the system to run faster and faster. If it gets hotter, it will not only reduce the performance of the system, but also cause unstable phenomena such as system restart and crash.
