Abstract

The invention provides a distributed file storage system, which comprises a data storage server cluster subsystem and a file management server cluster subsystem, wherein the file management server cluster subsystem comprises at least two storage volumes; each storage volume at least comprises two storage node servers, the storage node servers in each volume are backups and mirror images of each other, and a difference of storage capacities of the storage node servers in each volume is smaller than a first set value; and the file management server cluster subsystem is used for customer file uploading, storage management and storage server cluster synchronization. The invention provides a large number of super-large scale extensible and loosely-coupled distributed file systems, the performance is greatly improved, the dynamic expansion is greatly improved, the system supports file second pass, streaming media real-time playing, oversized data file storage and multi-user file sharing andprotection, and the basic services are provided for a data storage technology of the present era of big data.

Description

technical field [0001] The invention belongs to the technical field of data storage, in particular to a distributed file storage system. Background technique [0002] The file system is the method and data structure used by the operating system to organize disk files, and the computer manages and stores data through the file system. The explosive growth of massive information in the era of big data has led to an exponential increase in the demand for data storage capacity. The single file system expands the storage capacity of the file system by increasing the capacity and number of hard disks, and its performance in terms of capacity size, capacity growth rate, data backup, data security and management is not satisfactory. [0003] Distributed file system can effectively solve this data storage and management problem. An ordinary or special-purpose computer provides remote file access by adding services. A distributed file system (DFS) is formed by clustering file server...
