Abstract

The invention provides a distributed file storage system and method. File names of the stored files are SHA1 values of the files. The system comprises a plurality of storage nodes and managing nodes; the managing nodes are in communication coupling with the storage nodes, and manage the storage nodes; the storage nodes express minimum memory management units by primary directory; memory capacity of the storage nodes are divided into one or more memory units according to the minimum memory management units, and is expressed by one or more letters of predetermined positions in the file names of the stored files according to priority serial numbering and names of secondary directories of the storage nodes. According to the invention, retrieval and positioning of the files can be accelerated.

Description

technical field [0001] The present invention relates to the field of file storage, and more specifically, to a distributed file storage system and a file storage method used in the distributed file storage system. Background technique [0002] With the development of digital technology, the amount of files that need to be stored is increasing. For the massive sample files accumulated over the years, if a single storage device is used, on the one hand, it is difficult to have a large enough storage capacity, and on the other hand, it will become a single-point bottleneck for the entire data access. [0003] An effective way to store massive sample files is to store the sample files in a distributed storage system. In a distributed storage system, on the one hand, the total storage capacity of the system can be increased by adding computers to meet the demand for large-capacity storage; on the other hand, each computer in the network can process files stored on the current co...
