Method for reducing energy consumption of server by using mixed storage of solid-state drive and mechanical hard disk

Abstract

The invention belongs to the technical field of operation systems of servers and particularly relates to a method for reducing energy consumption of a server by using mixed storage of a solid-state drive and a mechanical hard disk. The method disclosed by the inventing is specifically realized by the following steps: for a read request of disk data, looking up a read request of disk data from a solid-state drive buffer zone and a cache zone; if the read request is hit, directly returning back to avoid the read operation of the mechanical hard disk; for a read request of disk data, writing a write request of the disk into the solid-state drive buffer zone, then periodically writing back to the mechanical hard disk and sorting the write operation for the disk position before writing back to reduce the invalid motion of a magnetic head; and controlling operation parameters of the mechanical disk according to an actual work load and a data access mode and reducing the rotating speed of the mechanical hard disk during idle operation and even closing the mechanical hard disk, so as to further reduce invalid energy consumption. According to the method, the energy consumption caused by the mechanical hard disk can be reduced and the work efficiency of the server can be increased, and thus the integral energy consumption of the server system is reduced.

Description

technical field [0001] The invention belongs to the technical field of server operating systems, and in particular relates to a method for reducing server energy consumption by using a solid-state hard disk and a mechanical hard disk for mixed storage. Background technique [0002] In today's world, the total amount of energy storage is decreasing, while the total energy consumption in the world is increasing day by day, which makes energy-saving technology more and more attention. With the continuous development of science and technology, the popularity of computer servers is getting higher and higher, and its manufacturing cost is getting lower and lower, especially with the rapid development of cloud computing in recent years, major companies have launched their own data centers, which The server scale even reaches millions. The energy consumption of such a large number of servers is very high, so how to reduce the energy consumption of the servers has become an importan...
