Storage cache optimization method and system, equipment and medium

Abstract

The invention discloses a storage cache optimization method and system, equipment and a storage medium, and the method comprises the following steps: building an independent redundant disk array through employing a plurality of hard disks, and building a logic volume based on the independent redundant disk array; creating a logic unit corresponding to the logic volume on the logic volume, and creating a virtual volume on the logic unit; creating a virtual block of the input / output management layer based on the virtual volume, and monitoring whether read-write operation exists or not in real time; and in response to the existence of the read-write operation, storing the data of the read-write operation into the virtual block. According to the storage cache optimization method and system, the equipment and the medium provided by the invention, the virtual block is arranged between the independent redundant disk array and the file system, so that the application program reaches the virtual block firstly during reading and writing, and the storage read-write speed and the storage performance are greatly improved.

Description

technical field [0001] The present invention relates to the field of storage, and more specifically, refers to a storage cache optimization method, system, computer equipment and readable medium. Background technique [0002] Now for the use of storage servers, higher read and write speeds are required under the premise of system stability, and the read and write speeds directly affect the use of applications. There are still a large number of storage systems on the market that use mechanical hard drives, and many low-speed mechanical hard drives often become the bottleneck of storage performance. Existing servers are equipped with memory, how to make good use of memory has become the key. [0003] After the application sends the data to the storage, it will first go to the memory and then be written to the disk. Among them, in order to improve bandwidth, multiple disks are formed into a disk array, that is, a raid. Format the file system after creating a logical volume o...

AI Technical Summary

Problems solved by technology

Format the file system after creating a logical volume on the raid. In the existing system, there is no cache between the raid and the file system. Users directly read and write data through the file system, and the read and write speed is often slow.
