Abstract

The invention provides a distributed storage cache management method and system, a storage medium and equipment. The method comprises the following steps: selecting object granularity and stripe width in a distributed underlying storage cluster based on the rated size of a file; fragmenting data of the file into a plurality of object units based on the object granularity and the stripe width, and writing the object units into a distributed underlying storage cluster in a manner of taking the object as the granularity, wherein the writing in the manner of taking the object as the granularity meets a locality principle; in response to a received read request sent by a client, searching in the cache according to the read request; in response to the fact that the data corresponding to the read request does not exist in the cache, performing prefetching management on the distributed underlying storage cluster by taking the object as the granularity, constructing the cache, and searching in the cache again according to the read request; and in response to the data corresponding to the read request found in the cache, returning the corresponding data and cache hit from the cache. According to the method, the cache space is saved, the prefetching hit rate is increased, and the overall IO performance of storage is improved.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to the technical field of distributed storage, and in particular to the technical field of cache management of distributed storage. Background technique [0002] With cloud computing and digital transformation, the amount of data generated grows exponentially, so there are new technical requirements for massive data storage. Although traditional storage has the advantages of mature technology, good performance, and high availability, in the face of massive data, its shortcomings are becoming more and more obvious, such as poor scalability, high cost, single point of failure and performance bottlenecks. In order to overcome the above shortcomings and meet the storage requirements of massive data, a distributed storage technology has emerged under the current technical background. A distributed storage system usually includes a master server, a storage server, and multiple cl...
