Embodiment Construction

[0042] 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.

[0043] The present invention implements the layered, segmented file and segmented continuous storage of the video stream data in the storage system through the stream data storage model of the video data created in the storage system in advance. Among them, the streaming data storage model of video data implements functions such as layered storage management of video streaming data, continuous disk storage, offline replication of disk partitions, and sleep sche...

Abstract

The present application discloses a method and device for storing video stream data, which acquires the video stream data to be stored, caches the video stream data to be stored into a plurality of video data files with a preset capacity, and then determines according to a preset scheduling strategy The video stream data to be stored is the target storage level among multiple storage levels in the storage system; the video stream data to be stored is stored in the first available custom partition of the target storage level according to the time sequence of the video data files Among the multiple contiguous available data slices corresponding to the first available block file of . Realize the layering, block file and continuous storage of video stream data, avoid discrete storage of video stream data, and improve disk I / O throughput and concurrent write performance of the storage system.

Description

technical field [0001] The present invention relates to the technical field of data storage, and more specifically, to a method and device for storing video stream data. Background technique [0002] In ultra-large-scale smart cities, especially in the application of smart transportation, as many as tens of thousands of high-definition cameras are connected, and its storage management capabilities are difficult to meet. For example, tens of thousands of high-resolution front-end network videos such as 720P and 1080P are connected at the same time. Taking a video stream of 1080P and 30 frames per second as an example, the video data rate generated by it is 750Mb / s. Compared with the H.264 video compression coding algorithm, the code rate of the generated video data is also 4 ~ 8Mb / s. As the number of connected video data channels continues to increase, the aggregate I / O throughput of disks in NVR and other storage systems has dropped sharply, and it cannot be greatly improve...
