A distributed file system and method for controlling file storage in the system

Abstract

The invention discloses a distributed type file system and a method of controlling the file storage in the distributed type file system. The method includes the steps that after a controller receives a storage file command of a client-side, a data server is chosen, identification information of the data server and metadata of a file to be stored are stored, the identification information of the data server is returned to the client-side, and the file to be stored is stored on the data server in the original format by the client-side. By using the distributed type file system and the method of controlling the file storage in the distributed type file system, complexity of the system can be effectively reduced, safety of the metadata of the file is simultaneously improved, and thereby the safety of the system is ensured.

Description

technical field [0001] The invention relates to the field of distributed file systems, in particular to a distributed file system and a method for controlling file storage in the system. Background technique [0002] In the field of broadcasting and television, the objects to be processed are massive video files and audio files. Traditionally, disk arrays are used to store these files. Therefore, the storage of these files is limited by the architecture of ordinary disk arrays, and the storage performance is limited. on the head of the disk array. When storage capacity expands, storage performance does not scale with it. As the scale of the system expands, it will soon encounter a bottleneck in storage performance. In order to solve this problem, a cluster network storage (Network Attached Storage, NAS) appeared, which can realize simultaneous expansion of storage performance and storage capacity, and solve the problem of system expansion, but the cost of the disk array of...
