Abstract

The embodiment of the invention discloses a method for managing the power supply of a solid hard disk storage system. The method comprises the following steps: reading a previous operating frequency of the solid hard disk, wherein the previous operating frequency is used for recording the frequency, at which the solid hard disk is visited; and disconnecting or connecting the solid hard disk according to the previous operating frequency of the solid hard disk. The power supply management method adopts the storage system controller to manage the power supply of the solid hard disk in a target-oriented manner according to the previous operating frequency of the solid hard disk, thereby allowing various storage devices to managing the power supply actively and reducing the energy consumption of the storage system.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a power management method and device for a solid-state disk storage system. Background technique [0002] Solid State Disk (SSD) is a technology that abandons traditional magnetic media and uses electronic storage media for data storage and reading. Because it breaks through the performance bottleneck of traditional mechanical hard disks, it has extremely high storage performance. It has outstanding application performance in some military systems and high-performance computing research fields, and is very likely to replace some expensive mainframe systems. Since the development of traditional storage has been unable to break through the bottleneck of performance for many years, solid-state storage is considered to be a technological innovation in the next-generation storage industry. Not only that, some industry insiders define solid-state storage as one of the five technologies tha...
