Abstract

The invention discloses a data storage management method and equipment thereof. Each basic unit of an Internet protocol storage area network (IPSAN) space is divided into a basic data region and at least one enhanced data region. The method comprises the following steps of: receiving video monitoring data with a basic layer and an enhanced layer by using storage equipment and writing the basic layer data into the basic data region and the enhanced layer data into each enhanced data region according to the video monitoring data of each time unit; when the basic data region of the last basic unit is fully written, starting to rewrite from the basic data region in the first basic unit; when each enhanced data region in the last basic unit is fully written, starting to rewrite from the corresponding enhanced data region in the first basic unit; and building index information by using the storage equipment according to the storage conditions of the video monitoring data.
