Abstract

The invention discloses a local caching method and device based on a lease lock mechanism. The method comprises the steps of when a storage system receives a data access request sent by a client, determining a priority of the client; sending lease authority to the client according to the priority of the client; and sending target data to the client for caching, thereby enabling the client to operate the cached target data according to the lease authority. Through the lease lock mechanism, the client can cache data in the storage system to the local client, so data exchange processes between the client and a server in which the storage system is located are reduced, read operations for files and the operations for a path list are reduced, paths are shortened, the delay is reduced, and the data access capability of the storage system is improved.

Description

technical field [0001] The invention relates to the field of storage, in particular to a caching method and device of a lease lock mechanism. Background technique [0002] With the development of Internet technology, storage systems need to support massive amounts of data, and need to support read and write operations with clients. [0003] In the prior art, in order to improve the performance of the client for reading data from the storage system, many methods for improving the storage system are provided, such as providing high-performance storage hardware devices or developing high-performance software. [0004] However, when the client accesses the data in the storage system, it is all online. Due to the difference in the network, there will be different delays, which seriously affects the client's read and write operations on the data. Contents of the invention [0005] In view of this, the embodiment of the present invention provides a local caching method and devic...
