Abstract

The embodiment of the invention provides a storage method and device based on data content identification. With the method and device based on data content identification, data from a host machine are received; the data content is scanned to acquire the format features of the data; the format features are matched with the format features in a content feature bank to judge the attributes of the data; the data are stored by classifications according to the attributes of the data so that the storage device can acquire the attributes of the data to be stored and optimize the data, thus improving data storage performance of the storage device.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a storage method and device based on data content identification. Background technique [0002] In the current storage system, the basic data storage operation is: the storage controller receives a write request from the host, performs a write operation on the hard disk or disk array according to the write request, and stores data on the hard disk or disk array. [0003] In the existing technology, the storage medium cannot perceive the upper-layer application, and cannot obtain the specific attributes of the data. For example, if the data currently to be stored is a frame of a video, a frame of MP3, a text or a database record, the storage medium cannot It is learned that the storage performance improvement of the current storage system is not obvious, and better performance optimization has not been achieved. Contents of the invention [0004] The embodiment of the present invent...
