DATA ACCESS METHOD BASED ON FEATURE ANALYSIS, STORAGE DEVICE AND STORAGE SYSTEM

摘要

A data access method based on feature analysis, a storage device and a storage system. The method comprises: carrying out file feature analysis on a file to be stored, and acquiring a file feature value of the file to be stored; a storage device generating a file feature value record according to the file feature value of the file to be stored, and storing the file feature value record and the correlation between the file feature value record and the file to be stored in a pre-set mapping table; when the storage device receives a data management command of a storage server, generating a condition file feature value corresponding to the data management command, wherein the condition file feature value is used for representing a query condition corresponding to the data management command; and the storage device matching the file feature value record in the pre-set mapping table according to the condition file feature value to acquire a file name of a required target file or a physical address of the target file. By means of the method, the load of a storage service can be effectively reduced, so that the performance of a data storage server does not decrease due to an excessive load.
