File memory method, apparatus and system

Abstract

The embodiment of the invention discloses a file memory method, a device thereof and a system thereof. The method comprises the following steps: the size of continuous physical blocks of memory is preset; and file data are stored in the preset continuous physical blocks successively. During the file memory process in the embodiment of the invention, the continuous physical blocks are distributed to files and a continuous memory of the files is ensured in the continuous physical blocks, thus being capable of setting the pre-reading strategy of the files and improving the reading performance of a file system.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a file storage method, device and system. Background technique [0002] In a file system, the data of a file includes two parts: the metadata of the file and the content of the file. The metadata of a file includes attribute information of the file and the location of the file content in the storage medium; the content of the file is the information recorded in the file. When reading the data of a file, the metadata of the file must first be found, and then the content of the file stored in the storage medium can be found according to the information in the metadata. [0003] In the currently commonly used storage media based on head drives, the number of head movements is a key factor affecting performance when reading data, so how to make the data as continuous as possible in the design of the file system, thereby reducing the number of heads To improv...

Problems solved by technology

[0008] The data of the file is not guaranteed to be continuously distributed, so that the read-ahead operation cannot be effectively optimized; at the same time, the file metadata is discretely distributed, and the reading efficiency is low
