Method and device for controlling fan speed of storage device and storage device

Abstract

The embodiment of the invention discloses a method, device and facility for controlling the speed of a fan of a storage facility, a computer readable storage medium and the storage facility. The method includes the steps that temperature information corresponding to temperature sensors prearranged on all heating components in the storage facility is obtained; according to the temperature information and contribution weight values of the whole temperature of the storage facility of all the heating components, PWM values corresponding to all the temperature information are calculated, and the maximal PWM value is selected from all the PWM values to serve as the optimal PWM value; the optimal PWM value is converted into a register value of a control chip of the storage facility, the rotatingspeed of the fan of the storage facility is controlled according to the register value, and the linear relationship between the PWM values and the rotating speed is preset for the fan, so that the rotating speed of the fan is controlled by the different PWM values to meet the radiating requirements of the storage facility. According to the technical scheme, the normal radiating requirements of thestorage facility are met, and the stability of the storage facility is improved; continuous high-speed rotating of the fan is avoided, and the service life of the fan can be prolonged.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of heat dissipation, and in particular, relate to a fan speed control method, device, device, computer-readable machine storage medium, and storage device of a storage device. Background technique [0002] With the rapid development of data storage technology, users have higher and higher requirements for the security and stability of storage systems. It is critical for storage devices to work stably for a long time, and heat dissipation is crucial for long-term stable operation of storage devices. important part. [0003] During the working process of the storage device, it is inevitable to generate heat, and different components have different heating efficiencies. For example, the Intel processor and some main chips of the storage device are the main heat sources of the storage device. Generally, heat dissipation for storage devices can be achieved by adding heat sinks, fans, or met...

Problems solved by technology

[0004] The speed of the fan directly affects the effect of heat dissipation. The higher the speed of the fan, the better the heat dissipation effect. That is to say, the storage device with high heat generation needs a fan with a higher speed to dissipate heat; however, when the temperature of the device is not high, it does not need to High speed can get better heat dissipation effect, and long time running at high speed will affect the life of the fan
