Description

technical field

[0001] The invention relates to the technical field of computer storage systems, in particular to a method for organizing and accessing distributed file system directories. Background technique

[0002] With the rapid development of computer technology and the increasing amount of information, storage systems have become the bottleneck of computer systems, especially large-scale distributed computer systems. The distributed file system can manage the storage system conveniently and effectively, and give full play to the performance of the storage subsystem. attached figure 1 A typical structure of a distributed file system is given, which consists of multiple servers and multiple clients. According to functions, servers can be logically divided into metadata management servers and storage servers.

[0003] The researchers found that in most current applications, the number of metadata operations is far greater than the number of ordinary file reads and wri...
