Storage system and method for media applications

Abstract

The invention discloses a media application oriented storage system and method. The system comprises a hardware layer, a logic layer and an application layer, wherein the hardware layer comprises a small storage module and a large storage module; the logic layer comprises a general file management module, a service intelligent analysis module in charge of predicting the service trend, and a power-saving intelligent management module in charge of managing the hard disk state in the large storage module; the application layer comprises a general file operation interface and a service intelligent management interface; and on the basis of instructions of a media file system, the data block access frequency corresponding to files is judged, and the files are intelligently stored and managed according to the data block access frequency corresponding to the files. After a physical storage device finishes intelligent scheduling and processing of data blocks according to the instructions, the intelligent sleep, activation and work of the storage media are executed to achieve the effects of power saving and environmental protection; and the access to the media file system and the physical storage device by a variety of upper-layer applications is completely transparent, and a variety of performance and efficiency requirements of the upper-layer applications are safely ensured.

Description

technical field [0001] The invention relates to a storage system and method for media applications. Background technique [0002] In the current storage system field, virtual storage, hierarchical storage, cloud storage, high-performance storage, high-capacity storage, green storage, hibernation storage, FC storage, IP storage, cluster storage, disk array, tape library, and optical disk library have been widely used. , virtual tape library and other storage technologies. [0003] With the gradual deepening and development of radio and television media applications, users have increasingly prominent comprehensive requirements for differentiated support for hot and cold data for application access, hierarchical management, and energy conservation and environmental protection. However, the existing various storage technologies cannot meet this comprehensive requirement well, and there are many limitations, so they cannot meet user needs and cope with the development of deeper ...

AI Technical Summary

Problems solved by technology

However, for broadcast-level video and audio media applications, these general-purpose physical storage devices have not been deeply integrated with the media file system dedicated to media file access, and have not intelligently classified and identified the association between files and data blocks and specifically for media files. The system provides a transparent file-level interface function. Therefore, the media file system cannot be well adapted to the physical storage device, and the hot and cold data cannot be intelligently processed in a scientific, orderly and economical manner, thus failing to achieve green energy saving, Dynamic balance of hot data high performance support
