Embodiment Construction

[0067] Please see attached figure 1 As shown, the distributed storage system and method of the present invention include a client access interface 1, a management server 2, and a file deletion controller 3; also include metadata server cluster A, metadata server cluster B, data storage server cluster A, data Storage server cluster B, database server cluster A, and database server cluster B. All servers in cluster A and cluster B can be deployed in two computer rooms to achieve the purpose of mutual backup between the two computer rooms. If the conditions do not permit, it can also be deployed in one computer room in actual deployment. When one computer room fails, the other computer room can still provide the main service, so as to achieve the purpose of data redundancy in the computer room.

Abstract

The invention relates to a distributed storage system and method. The system of the invention comprises a client access interface, a management server, a file delete controller, a metadata server clusters, a data storage server clusters and a database server clusters, wherein the client access interface is connected with the server clusters respectively; the management server is connected with the metadata server clusters respectively; the file delete controller is connected with the data storage server clusters and the database server clusters respectively; the metadata server clusters, the data storage server clusters and the database server clusters are connected mutually; each of the metadata server clusters is connected with one of the data storage server clusters; and each of the metadata server clusters is connected with one of the data storage server clusters. By adopting the system and method of the invention, the reliable backup of data and the rapid operation can be ensured and the overall performance of the system can be greatly increased; and the system of the invention provides a perfect interface management software and the function of data recovery, the deleted data can be recovered in certain time, thus the function of automated management can be really realized.

Description

technical field [0001] The present invention relates to a storage system and method, in particular to a distributed storage system and method. Background technique [0002] With the development of the Internet and the popularization of users' broadband access, some large-scale websites have begun to provide data storage functions for individual users. Ordinary users can store their digital photos, data files and other information in such systems as long as they access the Internet, and can also obtain stored file information from the system at any time and anywhere connected to the Internet. While the system provides great convenience for ordinary users, it also puts forward higher requirements for the design of the system. The system must be able to support massive data files for high-speed reading and writing and have certain disaster recovery capabilities. Current professional storage products such as SAN and NAS are not suitable for Internet applications due to their hi...
