Data storage system and method

Abstract

The invention provides a data storage system and a method for storing data by using the system. The system comprises a plurality of disk storage units, a redundant strategy database and a storage control unit. The data storage method and the system select redundant strategies respectively according to different data units, save disk spaces on the basis of system safety guarantee, further improve system performance, and reduce operation cost successfully.

Description

technical field [0001] The invention relates to the field of file redundancy storage, in particular to a data storage system and a data storage method. Background technique [0002] With the rapid development of the broadband market and the surge in the number of users, the scale of streaming media video applications such as VOD video on demand and other systems is becoming larger and larger. The interactive system of the radio and television industry requires a storage system with the characteristics of large capacity, high read and write performance, and high security. How to store and manage media files efficiently and safely is a major challenge for the radio, television and video industry. [0003] Currently, most video-on-demand solutions mainly use a video server directly connected to a disk array (that is, RAID) for data storage. This technology combines multiple independent hard disks into a hard disk group in different ways. Compared with a single disk, the perfor...

AI Technical Summary

Problems solved by technology

In the actual stored media files, some files are highly popular, and some files are rarely played on demand. The security requirements and read and write performance requirements for these files are different. When some files are improved through redundancy, When the security of files with high security requirements or high read and write performance requirements is required, the same configuration should be made for other files, which will cause a waste of disk space
