Abstract

The invention provides a distributed file system and a data access method thereof. The system comprises at least one client server, a metadata central server, at least one metadata server and at least one object server, wherein the at least one client server is used for receiving an access request from a client; the metadata central server is used for returning a currently available global uniquemetadata server identifier of the metadata server to the client server according to the access request of the client; the at least one metadata server is used for receiving file information transmitted according to the global unique identifier of the metadata server by the client server, and returning a currently available global unique object server identifier of the object server to the client server according to the file information; and the at least one object server is used for generating an access result in response to access contents transmitted according to the global unique identifier of the object server by the client server, and returning the access result to the client by the client server. The distributed file system and the data access method thereof greatly improve the reliability of the system at the same time of not influencing the data transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a distributed file system and a data access method thereof. Background technique [0002] In the field of computer storage, cloud computing (Cloud Computing) is the development of distributed processing (Distributed Computing), parallel processing (Parallel Computing) and grid computing (Grid Computing), or distributed processing, parallel processing and grid computing. Commercial implementation of computer science concepts. The basic principle of cloud computing is: by distributing calculations on a large number of distributed computers instead of local computers or remote servers, the operation of the enterprise's data center is similar to the Internet, enabling the enterprise to switch resources to the required applications. , to access computers and storage systems as needed. In other words, cloud computing is to use a specific network computer group to realize the...
