Problems solved by technology

[0002] As a high-performance and highly reliable storage technology, RAID (Redundant Array of Independent Disks) has been widely used in storage systems. RAID uses data striping technology to distribute and store data in blocks In multiple disks, the data can be processed concurrently, which effectively improves the overall IO performance of the device. In addition to improving the IO performance through RAID technology, the IO performance can also be improved by scheduling data read and write requests through the IO scheduling method However, there is a lack of a mature IO scheduling method in the prior art, which leads to the low storage efficiency of the current storage system using RAID technology, which limits the further improvement of the IO performance of the device

Abstract

The invention discloses an IO (Input / Output) scheduling method. For a disk in a storage system, the continuity of stripe access can be improved, and the data read-write efficiency can be improved, so that for a storage system applying an RAID (Redundant Array of Independent Disk) technology, data read-write requests with a head-to-tail connection relationship between starting and stopping stripes can be merged together and added into a request queue; therefore, the disk access frequency is directly reduced firstly, and then the storage system is accessed according to the merged data read-write request, so that the stripe continuity of disk access can be improved, the data processing efficiency is improved, and further improvement of the overall IO performance of equipment is promoted. The invention also discloses an IO scheduling device and equipment and a computer readable storage medium, which have the same beneficial effects as the IO scheduling method.
