Embodiment 1

[0072] Embodiment 1. A method for performing file operations in a system where multiple storage media coexist, the multiple storage media at least including one or more first storage media, and one or more second storage media; image 3 As shown, the method includes:

[0073] S110. According to the access statistics information of each file stored in the system, filter out the files satisfying the heating trigger condition;

[0074] S120. Periodically copy files that meet the thermalization trigger condition, and when the absolute value of the difference between the predetermined performance parameters of the first storage medium and the second storage medium is greater than a preset threshold, then the thermalization trigger condition is met When the files are copied, they are preferentially copied to storage media with high predetermined performance parameters.

[0075] In this embodiment, the file refers to a set of related information defined by the creator, which can be l...

Embodiment 2

[0114] Embodiment 2. An apparatus for performing file operations in a system where multiple storage media coexist, and the multiple storage media include at least one or more first storage media and one or more second storage media; Figure 4 As shown, the device includes:

[0115] The file access statistics module 102 is configured to filter out files satisfying the heating trigger condition according to the access statistics information of each file stored in the system;

[0116] The file migration module 103 is configured to periodically copy files that meet the heating trigger conditions, and if the absolute value of the difference between the predetermined performance parameters of the first storage medium and the second storage medium is greater than a preset threshold, then the file that meets the heating trigger condition will be copied. When copying files with optimized trigger conditions, they are preferentially copied to storage media with high predetermined perform...

Embodiment 3

[0215] Embodiment 3. A system in which multiple storage media coexist, including multiple storage media; the multiple storage media include at least a first storage medium and a second storage medium; the first storage medium includes one or more; The second storage medium includes one or more;

[0216] like Figure 12 As shown, the system also includes:

[0217]A processor, configured to filter out files satisfying the heating trigger condition according to the access statistics information of each file stored in the system; periodically copy the files satisfying the heating trigger condition, when the first storage medium, When the absolute value of the difference of the predetermined performance parameter of the second storage medium is greater than the preset threshold, when copying the file satisfying the heating trigger condition, it is preferentially copied to the storage medium with the high predetermined performance parameter.

[0218] Optionally, the processor is f...

Abstract

The present invention provides a multiple types of storage media coexistence system as well as a method and an apparatus for performing a file operation. The multiple types of storage media at least comprise one or more first storage media and one or more second storage media. The method comprises: screening out a file that meets a thermalization trigger condition according to access statistic information of each file stored in the system; and periodically copying the file that meets the thermalization trigger condition, and if an absolute value of a difference value of predetermined performance parameters of the first storage media and the second storage media is greater than a preset threshold, preferentially copying the file that meets thermalization trigger condition to a predetermined storage medium with a high performance parameter . The present invention provides a file operation scheme applicable to the multiple types of storage media coexistence system.

Description

technical field [0001] The invention relates to the field of storage, in particular to a system in which multiple storage media coexist and a method and device for performing file operations. Background technique [0002] With the development of the times, people's demand for file (such as but not limited to multimedia files such as video) services is getting higher and higher. Traditional single servers can no longer meet the needs of practical applications. Server clusters and distributed storage technologies have emerged as the times require. [0003] Several typical application scenarios of storage clusters are shown in Figure 1(a)~(c). In these scenarios, when file storage is shared, all shared storage methods as shown in Figure 1(a) are used. When the file storage is not all shared, there are two ways, one is the way of mutually exclusive storage of all files, as shown in Figure 1(b), and the other is partial shared storage as shown in Figure 1(c) , some mutually exc...
