Problems solved by technology

[0003] However, most distributed storage systems generally use the method of writing double copies of each written data, or storing the disk file data of the virtual machine, which wastes storage space and cannot solve the problem when a large number of client read operations single point of failure and performance bottlenecks; and when data is updated synchronously, it does not have the function of multiple metadata servers in the cluster to cooperate to provide read and write services externally

Abstract

The invention discloses a metadata cluster distribution storage system and a storage data reading and writing method. The metadata cluster distribution storage system comprises a storage network platform and a management network platform, wherein the storage network platform is used for storing data and transmitting the data to a client, the management network platform is used for storing metadata and the information about the position where the data corresponding to the metadata are stored in a storage server cluster, the reading and writing request of the client is responded to according to a preset flow distribution strategy, the data file copy request in the storage network platform is controlled, and the management network platform is of a topological structure.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a metadata cluster distributed storage system and a method for reading and writing stored data. Background technique [0002] In the digital information age, the total amount of global information data is growing at an alarming rate. According to the survey results of the Internet Data Center (IDC), the total amount of data created and copied globally in 2011 was 1.8ZB, and compared with the same period in 2010, the amount of data increased by more than 1ZB. The rapid growth of information data, on the one hand, poses a severe test to the storage, calculation, and extraction of information data, and on the other hand, puts forward stricter requirements on the disaster recovery system, backup, and archiving of information data. In this case, distributed storage technology came into being. [0003] However, most distributed storage systems generally use the method of writing double co...
