Embodiment Construction

[0072] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0073] figure 1 Shown is a schematic diagram of the network layout structure of the clustered NAS system. The clustered NAS system has its own operating system and clustered file system, and provides users with file data access services through the network file sharing protocol. Such as figure 1 As shown, the operating system, the cluster f...

Abstract

An embodiment of the invention provides a distributed cache data access method and device. According to the method, a first server receives a first access request sent by a user, and the first access request carries a target data block index to be accessed; the first server determines a first hash value of the target data block index and determines a second server of storing the target data block index according to correspondence between the set hash value and the servers; the first server transmits a second access request carrying the target data block index to the second server, so that the second server queries a third server which caches corresponding data blocks of the target data block index, according to the correspondence between the set data block index and the servers; the first server receives access response transmitted by the second server, and the access response carries query results of the third server querying the cached target data blocks. Through the application of the distributed cache data access method and device, data access efficiency of clustered file systems is improved and the performances of the clustered file systems are improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer information technology, and in particular, to a distributed cache data access method and device. Background technique [0002] With the rapid expansion of data storage requirements and scale in various industries, the application of cluster storage systems is becoming more and more extensive. Cluster network attached storage NAS (Network Attached Storage) system, as one of its typical representatives, provides users with high-performance, large-capacity, and highly scalable data access services. [0003] In a clustered NAS, one server usually stores and manages the cache information in the entire clustered NAS. After any server in the clustered NAS receives a read request or a write request, it will query the cache management server for the cache of the data that needs to be read or written. information. However, this will cause the cache management server to inefficiently proce...
