The Key Technology and Realization of Storage Visualization

Storage technology goes though the variations from single disk, tape and RAID to storage networking. Now storage area networks (SAN)is the prevalent technology of storage networking, it provides high performance, high availability and high scalability etc. , but at the same time, it results in the complications of storage environment and storage management. Storage virtualization is the effective means to resolve the problem of storage management. This paper mainly analyzes the storage virtualization in SAN, discusses its key technology and main implementing methods.
