A kind of temperature control method and device of magnetic disk

Abstract

The invention provides a temperature control method and device for a magnetic disk, and the method comprises the steps: obtaining the values of all preset temperature control reference parameters of the magnetic disk; determining a target input / output rate required by the magnetic disk based on the values of all preset temperature control reference parameters of the magnetic disk, wherein the temperature of the magnetic disk can be controlled in an expected range when the magnetic disk employs the target input / output rate for input / output; controlling the magnetic disk to carry out the input / output at the target input / output rate, so as to enable the temperature of the magnetic disk to be controlled in the expected range. Therefore, the invention proposes a scheme of indirectly controlling the temperature of the magnetic disk through controlling the input / output rate of the magnetic disk, so the power consumption of the magnetic disk can be reduced through the reduction of the input / output rate of the magnetic disk when a solid-state disk needs to be cooled, thereby achieving the purpose of reducing the temperature of the magnetic disk, and achieving the high-temperature protection for the magnetic disk.

Description

technical field [0001] The invention belongs to the technical field of temperature control and high temperature protection of magnetic disks, and in particular relates to a temperature control method and device. Background technique [0002] With the development of technologies such as the Internet, cloud computing, and the Internet of Things, solid-state drives, as a new generation of storage devices, have been widely used. [0003] Solid-state hard disks do not have fans. When the ambient temperature rises, the temperature of solid-state hard disks will also rise accordingly, making it impossible to physically cool down. When the temperature of the solid-state hard disk is high, it may cause its performance to decline or even fail to read and correct errors, which seriously affects the life of the solid-state hard disk and shortens the storage time of data. Moreover, the high temperature will also damage the electronic components in the circuit related to the solid state ...

Problems solved by technology

[0003] Solid-state hard drives do not have fans. When the ambient temperature rises, the temperature of solid-state hard drives will also rise accordingly, and physical cooling cannot be performed.

When the temperature of the SSD is high, it may cause its performance to decline or even fail to read and correct errors, which seriously affects the life of the SSD and shortens the storage time of data.

Moreover, the high temperature will also damage the electronic components in the solid-state hard disk related circuit, resulting in circuit failure.
