Abstract

The invention discloses a load balancing optimizing method based on block level cloud storage. According to the method, a heteromorphosis part of a genetic algorithm is added to a load balancing strategy to improve accuracy of the strategy to search globally optimal solution as far as possible; simultaneously, a breakpoint resume function facing an internet small computer system interface (ISCSI) is designed, so that when a volume server is reselected for ISCSI reconnection, users which are uploading data needn't upload the data again, a system can automatically continue uploading from the breakpoint, and the reliability of the system is improved; and by means of existing isomerism storage environments, a hierarchical storage management mechanism based on volume life cycle is provided, and advantages and characteristics of different storage devices are fully utilized to further improving access efficiency of the system. The load balancing optimizing method can be used for solving the load balancing problem of a cloud storage system in the technical field of computer storage.

Description

technical field

[0001] The invention relates to the technical field of computer storage, in particular to a device for optimal management of block-level cloud storage based on load balancing multi-volume servers. Background technique

[0002] Cloud storage is an extension and development of the concept of cloud computing. It refers to the collection of various heterogeneous storage devices in the network to work together through cluster technology, distributed file system, grid technology, etc., to provide external security to users. , reliable and efficient data storage and data access services.

[0003] According to the different storage levels it provides, cloud storage can be divided into two categories: file-level cloud storage and block-level cloud storage. File-level cloud storage mainly refers to distributed file systems, which provide file-level storage access services through network file system access protocols; block-level cloud storage provides users with origi...
