Embodiment Construction

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0080] Video data, pictures, and audio data in the security industry are referred to as streaming data. Streaming data has the characteristics of large data volume, more writing and less reading, and fast coverage frequency. When storing streaming data in project applications, it is necessary to process a large number of new data writes Issues related to deletion of expired data, as well as hardware cost issues brought about by a large amount of streaming data storage. Shingled hard...

Abstract

The embodiment of the invention provides a data processing method and device, an SMR storage system and a storage medium. The method comprises steps of obtaining a data writing instruction; determining a target object block of the target data to be written in in an SMR area of the target SMR disk according to the data writing instruction; generating target main index information and target standbyindex information for the target data and the target object block; writing the target data and the target standby index information into a target object block; writing the target main index information into a CMR area or other storage media; and writing database index information of the target data into other storage media, wherein the database index information of the target data comprises the target Unit key and the identifier of the target object block. Through the database index information, the main index information and the standby index information, the data writing sequence among thedata blocks in the SMR area is not limited, the operability of SMR disk data storage is improved, and the data storage efficiency is high.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a data processing method, device, SMR storage system and storage medium. Background technique [0002] SMR (Shingled Magnetic Recording, shingled magnetic recording) disk is a disk data storage technology that partially overlaps the data tracks on the disk, just like the tiles on the roof, so it is called shingled magnetic recording technology. SMR technology can greatly increase disk storage density. However, due to its special storage structure, SMR disks do not support random data writing and in-place updating, resulting in poor data storage operability and low data storage efficiency. [0003] Therefore, it is hoped that the operability of SMR disk data storage can be improved, and the efficiency of data storage can be increased. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a data processing meth...
