Abstract

The invention discloses a bandwidth control method. The method comprises the following steps: acquiring the temperature of a hard disk; judging whether the temperature is between a first threshold value and a second threshold value or not; in response to the fact that the temperature is between the first threshold value and the second threshold value, reducing the numerical value of a register ofthe hard disk from a default maximum value to a preset value; determining a bandwidth drop ratio based on a current value of the register of the hard disk; calculating a difference value between the bandwidth drop ratio and a target drop ratio corresponding to the temperature; and reducing the current numerical value of the register by a value corresponding to the difference value according to thedifference value, and returning to the step of determining the bandwidth drop ratio until the bandwidth drop ratio reaches the target drop ratio. The invention further discloses computer equipment and a readable storage medium. According to the method disclosed by the invention, the read-write bandwidth of the solid state disk can be effectively controlled, so that the temperature rising speed iscontrolled. And the read-write bandwidth of the solid state disk is reduced by reasonably setting the value of the subtrahend and adopting a method of gradually reducing the value of the register bygrades, so that the reduction speed and the reduction accuracy of the bandwidth can be considered.

Description

technical field [0001] The invention relates to the field of temperature control, in particular to a bandwidth control method, device and storage medium. Background technique [0002] After the solid state drive is powered on, the temperature of the solid state drive will continue to rise due to the need to process various io requests and the influence of the ambient temperature. During the normal use of the SSD, the cooling fan should be kept running. However, if the cooling fan fails for some reason, when the temperature of the solid-state drive reaches a certain threshold, the temperature control strategy in the solid-state drive firmware will usually be triggered to slow down the temperature rise of the solid-state drive. Reasons to buy time. Among them, the temperature control strategy usually achieves the purpose of controlling the temperature rise rate by controlling the bandwidth. [0003] At present, most manufacturers use methods including but not limited to mod...
