Abstract

The invention relates to a large-scale distributed storage system in the technical field of computer network application, comprising at least one management node which is used for storing a name space, metadata information, an object number and address information of an object, a plurality of storage nodes which are used for storing corresponding object data and a plurality of super clients; the super clients access the management node by the storage node, search for the object number and the address information of the object of a file to be accessed in the management node and access the corresponding object data from the corresponding storage nodes; the management node comprises a file system which stores the name space and the metadata information of the object and a database which stores the object number and the address information of the object. Configurable automatic load balancing and data migration are adopted in the large-scale distributed storage system, the consistency of the data is periodically checked, and the junk data is periodically cleaned, therefore, various problems which are caused by manual operation are eliminated, and the large-scale distributed storage system has high expandability.

Description

technical field [0001] The invention relates to a device in the technical field of computer network application, in particular to a large-scale distributed storage system. Background technique [0002] In a traditional file storage system or file server, for example, based on Network Attached Storage (NAS), data is stored and managed by a huge, closed, and independent system. Enterprises often need to deploy multiple file servers to meet rapidly growing data processing demands. However, deploying multiple file servers will cause problems such as data migration, data sharing, load and capacity balancing, and high availability. These problems often require manual participation to solve, which will cause many hidden dangers. [0003] In the traditional file system, each file server limits the access bandwidth of the entire file system, and since metadata and data are stored in a separate system, when more and more users access, frequent random read and write operations make th...
