Problems solved by technology

When the system performs streaming media storage and video streaming playback, the randomness of reading and writing hard disk data is relatively large. At this time, magnetic head re-addressing and positioning will occur. If the positioning data is read too small and the probability of random reading and writing data is high When it is large, it will cause the head to be in the addressing state most of the time, thus causing low disk I / O throughput efficiency

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Such as figure 1 As shown, a method for optimizing a disk storage strategy includes the following steps:

[0021] (1) Process the media stream data before sending to the disk, and divide it into media stream data blocks according to the rules:

[0022] Dividing the media stream data into data blocks according to a certain size can avoid disk fragmentation, because fragmentation can lead to a decrease in disk I / O usage efficiency and space usage efficie...

Abstract

The invention provides a method for optimizing a disk storage strategy. Through storing media stream data in a partitioning manner, and generating an indexing file according to keyframes and storing the indexing file in an independent region, when data is played, the indexing file is loaded in internal storage, and specific media stream data block contents are played according to the indexing file, preventing large amount of disk random read operation when the data is read and improving disk throughput efficiency, so system fluidization and storage business are performed more smooth.

Description

technical field [0001] The invention belongs to the field of disk storage, and more specifically relates to a method for optimizing a disk storage strategy. Background technique [0002] In the video conferencing system, the combination of distributed storage and centralized storage is generally used for storage system layout. The system supports multiple storage server clusters. Storage nodes use ordinary hard disks or disk arrays for local storage. Different nodes Media data cannot be shared, so streaming and storage operations need to be performed on the same node at the same time. Streaming operations need to read disk data, and storage operations need to write data to disk, that is, disk data I / O operations are required. Based on this condition, it is necessary to optimize the storage and streaming strategies to improve the system disk IO throughput. [0003] For most IO operations, the data should be written or read as efficiently as possible with the upper limit of t...
