Embodiment

[0061] In the first aspect, the embodiment of the present invention provides a file copy storage method. A file copy storage method includes such as figure 2 S101 and S102 are shown.

[0062] S101: Obtain a target ID based on the storage IDs of multiple storage nodes and the evaluation coefficient of each storage node.

[0063] Wherein, the storage ID corresponds to the evaluation coefficient, the target ID is the storage ID corresponding to the optimal evaluation coefficient among the evaluation coefficients of each storage node, and the evaluation coefficient of the storage node represents the storage performance of the storage node for the copy of the target file.

[0064] S102: Store the copy of the target file in the storage node corresponding to the target ID.

[0065] In the prior art, by randomly obtaining a storage node to store a copy of the file, there may be an excessive amount of data stored by a certain storage node, resulting in unbalanced data load in the st...

Abstract

The embodiment of the invention provides a file copy storage method and device, a readable storage medium and electronic equipment, and the method comprises the steps: obtaining a target ID based on the storage IDs of a plurality of storage nodes and the evaluation coefficient of each storage node; wherein the storage ID corresponds to the evaluation coefficient, the target ID is the storage ID corresponding to the optimal evaluation coefficient in the evaluation coefficients of each storage node, and the evaluation coefficient of each storage node represents the storage performance of the storage node for the copy of the target file; and storing the copy of the target file to a storage node corresponding to the target ID. A storage ID corresponding to an optimal evaluation coefficient inevaluation coefficients is obtained as a target ID. The copy of the file is stored in the storage node corresponding to the target ID, so that the copy is stored in the storage node with the strongeststorage performance for the copy, the data load balance of the storage system is improved, and the data storage performance of the storage system is improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a file copy storage method, device, readable storage medium and electronic equipment. Background technique [0002] With the rapid development of mobile Internet and science and technology, various industries and fields of society will generate massive and diverse data. Therefore, one of the problems facing the field of cloud computing is how to efficiently and reliably store and manage massive data. . [0003] At present, a large amount of data relies on cloud storage systems for storage management. For the cloud storage system, the cluster in its cloud storage environment stores and manages the data based on the copy of the file, that is, the copy of the file is stored in different nodes, so that when the file of an accessed node fails, it can be accessed from other The node obtains a copy of the file to restore the data, ensuring the storage performance of the c...
