Problems solved by technology

[0004] However, with the increasing development of applications, the RAID storage method gradually shows the following defects: First, the entire file is stored as the basic unit in the RAID storage method. When multiple users access the same media file at the same time, Access speed will be limited
Secondly, when dynamically expanding the capacity of multiple existing hard disk drives, especially when expanding the capacity of hard drives using the RAID redundancy strategy, since the RAID redundancy strategy is implemented through hard disk mirroring, it is necessary to expand the capacity. Rebuilding the RAID strategy is costly and complex, and when there are users accessing media files, dynamic expansion will also affect the ongoing normal business

Embodiment Construction

[0014] Such as figure 1 As shown, the file storage system involved in the present invention includes a storage control unit 10 and a plurality of disk storage units 20. The storage control unit 10 is used to create a file and divide the file into a plurality of file blocks so as to be stored in the plurality of disk storage units 20. The storage control unit 10 can also detect the online status of the multiple disk storage units 20 (that is, the electrical connection status between the disk storage unit 20 and the storage control unit 10), and obtain a list of file blocks stored in each disk storage unit 20 . When a disk storage unit with a relatively large remaining storage capacity appears in the plurality of disk storage units 20 (for example, a new disk storage unit is added, or the original disk storage unit releases new available space, etc.), the storage The control unit 10 is also used to transfer part of the file blocks in the existing multiple disk storage units 20 t...

Abstract

The invention discloses a method for storing document and a storage allocation method for a document storage system using the document storage method for storage, wherein documents are divided into document blocks to be stored respectively in a plurality of disk storage units, so that the problem that when multiply users access the same document, the speed is limited is solved well. Simultaneously, the performance of disk storage units is further improved through document block redundancy and safety of the document storage system is improved effectively.

Description

Technical field [0001] The present invention relates to the field of file storage, in particular to a method of storing files in multiple storage units and a method of using the method to perform storage allocation to a file storage system including multiple storage units. 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 systems is becoming increasingly large. The interactive system of the radio and television industry requires the storage system to have the characteristics of large capacity, high read and write performance, and high security. How to store and manage media files efficiently and securely is a major challenge for the radio, television and video industry. [0003] At present, most of the video-on-demand solutions mainly adopt the way that the video server is directly connected to the disk array (that is, RAID) for data stora...
