Cache acceleration management method, system and device for volumes in storage, and storage medium

Abstract

The invention discloses a cache acceleration management method for volumes in a storage. The method comprises the steps of selecting a cache partition; acquiring data information of the cache partition, wherein the data information comprises a mode of the cache partition, a node ID of the cache partition and an IO group ID of the cache partition; traversing all the volumes in the storage, and determining a node ID of each volume and an IO group ID of each volume; according to the data information, the node ID of each volume and the IO group ID of each volume, determining a volume set serving as an acceleration object of the cache partition from all the traversed volumes; and sending acceleration starting instructions to any number of the volumes in the volume set so as to achieve cache acceleration of the volumes receiving the acceleration starting instructions. By applying the method, all the volumes, capable of being subjected to cache acceleration management, of the cache partitionare determined, so that the management efficiency of batch cache acceleration of the volumes is improved. The invention further discloses a cache acceleration management system and device for the volumes in the storage, and a storage medium, which have the corresponding technical effects.

Description

technical field [0001] The present invention relates to the technical field of storage, in particular to a cache acceleration management method, system, device and storage medium of volumes in storage. Background technique [0002] Volume, usually also called disk or partition, is the basic container unit for file management. According to its function, it can be divided into production volume, mirror volume, snapshot volume, clone volume, copy volume, copy volume, etc. [0003] In order to improve the performance of volumes on storage, cache partitions can be created to accelerate volumes, for example, creating cache partitions on SSDs (Solid State Drives) to accelerate volumes, and one cache partition can accelerate multiple volumes to accelerate. When creating a cache partition, you can use one or more nodes on the IO group to create it. For example, there are two nodes on a common IO group: node A and node B. You can create a cache partition through node A or node B alon...

AI Technical Summary

Problems solved by technology

When multiple volumes need to be accelerated in batches, because different volumes may belong to different IO groups or belong to different nodes in the same IO group, it is usually impossible to select a cache partition that can accelerate all the volumes to be accelerated, namely These volumes cannot be cache-accelerated with a cache partition

Therefore, for these batches of volumes to be accelerated, the solution in the prior art is to sequentially filter the cache partitions for each volume, and determine the cache partitions corresponding to each volume. Due to the large number of volumes, such a method can greatly reduce the management efficiency of bulk cache acceleration of volumes
