Abstract

The embodiment of the invention discloses a file layered storage method which is used for solving the problems that in the prior art, cold and hot files are roughly judged, the cold and hot degrees ofthe files cannot be truly reflected, consequently, file layered storage is inaccurate, storage devices with different properties cannot be reasonably distributed and effectively utilized, and practicability is low. The method comprises the steps of determining access popularity of a target file based on an average access frequency of the target file in a predetermined time period before a currentmoment and an average access proportion of the target file; and based on the access popularity of the target file, storing the target file on a storage layer matched with the access popularity. The invention further discloses a server.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of storage, and in particular, to a file hierarchical storage method and server. Background technique [0002] With the development of society, the amount of data that enterprises need to store is increasing, and the types of data to be stored are also increasing. Usually, various enterprises will purchase other storage devices to achieve the purpose of urgent expansion. Since the performance of the purchased storage devices is not uniform, how to rationally allocate and effectively utilize these storage devices with different performances is very important. [0003] At present, by judging the coldness and hotness of files in the enterprise system, and then storing the judged hot and cold files in layers, these storage devices with different performances can be reasonably allocated and effectively utilized. However, in the existing file hierarchical storage method, the judgment of ...
