Problems solved by technology

However, a cloud storage system is generally composed of multiple storage servers. When a server is fully loaded, it may not be able to meet the needs of the original hosting users.
If the principle of sequential storage is simply adopted, some storage servers may be overloaded and some servers may be under light load
In this way, the performance of the storage server with heavy storage load will degrade, and users will not be able to read and write data efficiently.

Embodiment Construction

[0030] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0031] figure 1 It is a structural diagram of a file storage management system of a cloud storage system of the present invention. As shown in the figure, when the user client accesses the system of the present invention for the first time, the user client first accesses the main volume management server, and the main volume management server allocates the corresponding main metadata server, and sends back information such as the IP address of the main metadata server to the Client, the client will record and save these IP information locally. Afterwards, whenever the client accesses the system of the present invention, it will directly search for the IP information of the corresponding master metadata server in the local record and connect to the master metadata server corresponding to the IP, and the master metadata server will automatically obtain the IP inf...

Abstract

The invention provides a file storage management system of a cloud storage system. The system comprises one or a plurality of management nodes, and one or a plurality of storage nodes (data nodes); in data establishment and storage, the system distributively establishes and stores the data on each storage node; in data establishment and storage, a system external interface supports a POSIX (Portable Operating System Interface of Unix) standard protocol, and the system controls a data diffluent mode through a master file management server, balances the load of each storage server, and keeps the performance and a primary storage data saving path of the server permanent.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a file storage management system of a cloud storage system. Background technique [0002] The physical location of traditional cluster storage data is relatively centralized, and data storage does not need to consider whether the load is balanced. In the process of implementing the present invention, the inventors found that cloud storage systems generally store data in a sequential manner. However, a cloud storage system is generally composed of multiple storage servers, and when a server is fully loaded, it may not be able to meet the needs of the original hosting users. If the principle of sequential storage is simply adopted, some storage servers may be overloaded and some servers may be under light load. In this way, the performance of the storage server with heavy storage load will be degraded, and users will not be able to read and write data efficiently. ...
