Embodiment Construction

[0017] The system will be further described below in conjunction with the accompanying drawings and the specific implementation and application process.

[0018] Such as figure 1 As shown, the whole system consists of seven functional modules, which are logical volume hosting module, logical logical volume management server load monitoring module, logical logical volume management server status monitoring module, virtual machine monitor hosting module, system central control module, logical The status of the logical volume management server listens to the management module and the client module, and these modules are respectively deployed on four types of nodes with different functions: the logical volume management server, the virtual machine server, the system central control server and the system client. Each module publishes its own functions through the Web Service interface for other modules to call, and through the coordination of the central control module of the syste...

Abstract

The invention relates to a cloud storage system with a balanced multi-server load. A conventional cloud storage system, in part, has defects that firstly, since the cloud storage system is tightly coupled with an own platform system, intersystem integration and secondary development are not facilitated; and secondly, logical volume management server bottleneck seriously affects the whole performance and the reliability of the system. According to the invention, multiple logical volume management server bottleneck manages a background storage device via logic volume management technology based on a colony; an intermediate control service coordinates and controls modules of the system to operate, and distributes storage resources for a user virtual machine; and besides, the reliability and the performances of the system are ensured via a fault management mechanism and a dynamic load equalization mechanism. The system provided by the invention achieves the reliable storage device management of a cloud storage server is achieved; on performance, the storage device reading / writing throughput capacity of the system is affectively improved, and averaged reading / writing response time is shortened.

Description

technical field [0001] The invention relates to the technical field of cloud storage, and relates to a cloud storage system with multi-server load balancing. Background technique [0002] Domestic cloud storage technology can be divided into file-level storage technology and block-level storage technology according to the level of storage provided. [0003] File-level cloud storage technology mainly refers to distributed file systems, which manage a series of storage resources distributed on the network and provide users with a complete set of file operation interfaces, such as Amazon Simple storage service (S3), Eucalyptus S3, OpenStack, Hadoop Distributed File System (HDFS) uses a distributed file system to provide background storage for user virtual machines. Distributed file systems have high security, scalability, and read-write efficiency, but file-level storage cannot provide users with raw block devices. [0004] Block-level cloud storage provides users with origin...
