Embodiment Construction

[0077] with attached figure 1 To illustrate the distributed storage system with p2p function proposed by this application. like figure 1 As shown, first, the client sends a read and write request to the central server, and the central server stores the file mapping information instead of the actual file content. As a specific implementation, a mapping table can be used, and the mapping table includes but is not limited to the file name , total length, location of the storage node where the file resides, etc., the mapping table can be organized and implemented in the form of a file or a database.

[0078] The central server finds the access address of the corresponding file from the mapping table, which corresponds to the addressable location of the storage medium on the specific storage node, and returns the location to the client, because the file is on the storage node It is block storage and the size of the block is fixed. The central server will not schedule the storage ...

Abstract

The invention provides a distributed type storage system having a p2p function and a method thereof. The method is characterized in that: a client side sends a read-write request to a central server; the central server finds out the access address of the corresponding resource from a mapping table, and sends the access address to the client side; and according to the address of the storage node returned by the central server, the client side sends the read-write request to a particular storage node, the storage node sends a health condition report to the central server, and the central serverperforms the p2p scheduling of the resources on the storage nodes according to resource information for reading and writing and health condition information of all storage nodes. The system and the method have the advantages that: an ultra-large-scaled distributed type storage system can be formed by the integration of low-grade machines, the equipment can be easily maintained, and the infinite horizontal extension capability is ensured.

Description

technical field [0001] The invention relates to a distributed storage system and method with p2p function, belonging to the field of streaming media storage. Background technique [0002] Traditional network storage systems use a single storage server to store all data, and the storage server will become the bottleneck of system performance and the focus of reliability and security, and has the defect of single point dependence. In addition, the price of traditional storage servers is also low. It is relatively expensive, and has relatively large defects in data recovery speed and maintainability, and it is difficult to meet the needs of large-scale storage applications. In order to solve these problems, the concept of network distributed storage technology is proposed. Network distributed storage technology is a technology that is transparent to users in terms of storage applications, but the actual physical storage is automatically distributed on different network storage...
