Background
The storage system is a system in which a computer is composed of various storage devices for storing programs and data, a control unit, a device (hardware) for managing information scheduling, and an algorithm (software). The data security and response speed of a storage system are one of the keys to evaluating the quality of the storage system. A copy of the data of the enterprise-level storage system is typically stored in several hard disks to increase the security of the data. However, when a system frequently reads and writes a certain group of hard disks (a main disk and a mirror disk thereof) in the system, the temperature of the hard disks is increased. High temperatures increase the likelihood of hard disk failure, which directly affects the data security and response speed of the storage system. Currently, there are external refrigeration devices to reduce the temperature, but the external refrigeration is only to balance the temperature of the overall system.
