Principle Analysis And Implementation Of Storage Virtualization

With growing explosion of data in SAN, storage virtualization technology must be used to satisfy the demand of storage resource management, sharing of data between of heterogeneous platforms, the availability and scalability of the storage system. The virtual storage are beginning to lead the direction of grid storage。The paper primarily probes into the virtual storage. Firstly, from the theory, the technology of distribute cluster is important for the virtual storage development. Moreover, the technology of the network virtualize storage space mapping is very important for researching the virtualize storage of distributing. Lastly, this paper brings forword the model of the virtualize Storage system. Based on the theory of the distribtute cluster, this paper researches the out of band technology's character and brings out an implement of virtualize storage.This paper mainly discusses the sort of virtual storage and Storage System Structure in implementing the distribute volume system. In SAN, the management of the data block is simple. The paper brings forword the distribute snapshot system with the new feather of the data instant recovery. And it resolves the question of I/O band and brings forword and implements a way of virtual storage.
