Embodiment Construction

[0036] Such as figure 1As shown, the cloud storage system is divided into two levels: metadata server set 1 (M0, M1, . . . , MN) and data block storage node set 2 (S0, S1, . . . , SN). The metadata server set 1 includes multiple metadata servers, and for any two metadata servers, the accumulation of data in each metadata server is the same. The two metadata service sets 1 are mutually redundant. Similarly, the accumulation of data owned by each data block storage node set 2 is the same. The system can determine which specific storage server node the user client wants to read and write according to the client network environment. The metadata server is responsible for managing the entire distributed file system and responding to the client's access to the file, accepting the write request from the write client and assigning it to the storage block, or accepting the request from the read client to read the file, and returning the location of the block corresponding to the file...

Abstract

The invention relates to the technical field of Internet information, in particular to a cloud storage system and an implementation method thereof. The cloud storage system comprises more than one metadata server sets and a plurality of data block storage node sets, wherein metadata server sets manage the whole distributed file system, respond an access of a client to a file, receive a writing request of a writing client and distribute the writing request to a storage block or receive a request of a reading client for reading a file and return to a position of a block corresponding to the file; and the reading client reads file blocks from corresponding blocks and combines the file blocks. In a system, the file is divided into one or more blocks; the blocks are scatteredly stored in the data block storage node sets; and storage nodes create, delete and copy the file blocks under the command of metadata servers. In the cloud storage system and the implementation method, the safety and the transmission efficiency are improved due to block redundancy distribution and block balance distribution, and the congestion probability is reduced. The cloud storage system and the implementation method are widely applied to cloud storage systems of enterprises.

Description

technical field [0001] The invention relates to the field of Internet information technology, in particular to a cloud storage system and an implementation method thereof. Background technique [0002] Cloud computing is the result of the mixed evolution and leap of concepts such as virtualization (Virtualization), utility computing (Utility Computing), IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). It provides a brand-new Internet business service model, that is, users can rent the required services through the network in an on-demand and easy-to-expand manner. Cloud computing technology uses the transmission capacity of the high-speed Internet to transplant resources such as computing, storage, software, and services from distributed personal computers or servers to large-scale high-performance computers, personal computers, and virtual computers that are centrally managed on the Internet, so that users Use these resour...
