Abstract

The invention provides a storage system based on a distributed cluster. A file size judgment module is used for judging the size of a client in-file, and when the size of the file is less than a firstpreset value, a storage processing module is used for storing the file to a caching module; the file size judgment module is further used for judging the size of a client reading file, when the sizeof the file is less than that of the first preset value, the storage processing module is used for feeding the judgment result of the file size judgment module back to a client, and the client is usedfor reading the file through the caching module; the catching size judgment module is used for judging the size of an aggregation file stored by the storage processing module, when the size of the aggregation file reaches a second preset value, a caching and processing module is used for writing the aggregation file, which is in the caching module, into an aggregation storage module. The storagesystem can be used for effectively reducing the times of writing a small file in a disk and improving reading hit rate.

Description

technical field [0001] The invention relates to the field of computers, in particular to a storage system based on distributed clusters. Background technique [0002] With the development of the times, a large number of data files are generated. The computer manages and stores data through the file system, and simply increases the number of hard disks to expand the storage capacity of the computer file system. In terms of capacity size, capacity growth rate, data backup, data Safety and other aspects of the performance are unsatisfactory. The distributed file system can effectively solve the problem of data storage and management. A file system fixed at a certain location can be extended to any number of locations or multiple file systems. Many nodes form a file system network. Each node can be distributed in different locations, and the communication and data transmission between nodes can be carried out through the network to establish a huge cluster system. When people ...
