Problems solved by technology

The traditional host-based virtualization management method adopts a symmetrical structure, any node in the cluster can perform virtualization management operations, and the consistency of metadata is maintained by communication between nodes, which increases the burden on the host and limits System scalability
In addition, due to the adoption of a symmetrical structure, this method does not support heterogeneous storage area network environments with different operating systems on front-end hosts

Embodiment Construction

[0050] The virtualization management system is mainly composed of the metadata server and the virtualization agent software on each front-end host, that is, the application server. The metadata server is mainly responsible for building the storage resources of different companies and different media in the storage area network into a storage pool, and providing virtual volumes for each application server on demand. It is also responsible for the management and configuration of storage resources, and provides advanced functions such as capacity expansion and data migration. The virtualization agent on each application server mainly realizes the address translation from the virtual logical disk to the actual physical disk, and reads the metadata of the corresponding virtual volume from the metadata server. In order to eliminate the single point of failure caused by one metadata server, two or more metadata servers can form a cluster. The hardware structure of the storage virtua...

Abstract

This invention relates to a store virtualization manage method based on metadata server belonging to store area net virtualization realm, characterized by the followings: virtual proxy module of each front-end host computer actualizing the shift from virtual logic reel to actual physical reel; one or multiple metadata servers forming physical reel with different storage device by global unique identifier and building storage pool to reflect metadata constructing reel of storage device; using managing module to actualize the control to metadata; building communicating association of virtual proxy module supplied with metadata information and managing module jointed with previously received identifier information to constitute corresponding virtual device via Ethernet. It can accomplish various virtual function, and ignore the effect of system throughput ratio and respond time.

Description

technical field [0001] A storage virtualization management method based on a metadata server belongs to the field of storage management, and in particular relates to the field of storage area network (SAN) virtualization management. Background technique [0002] Storage virtualization refers to a technology that separates specific storage devices from server operating systems and provides storage users with unified storage pools and logical volumes. Storage virtualization management in storage area network is a key technology to realize the full potential of storage area network. The traditional host-based virtualization management method adopts a symmetrical structure, any node in the cluster can perform virtualization management operations, and the consistency of metadata is maintained by communication between nodes, which increases the burden on the host and limits System scalability. In addition, due to the adoption of a symmetrical structure, this method does not supp...
