Technological research about storage virtualization based on promoting utilization of storage resources

With the explosive increase of storage data and the urgent need for storage space,the storage virtualization technology is widely used in the storage system.The text offers a storage virtualization architecture of double layer,combining the traditional storage virtua-lization technology with the virtual memory mechanism which has been applied in the memory management of operating system and will be expanded and led to the whole storage system.The architecture realizes the virtualization in the logical and the virtual level,shields the isomerism of the storage equipments and extremely improves the utilization ratio of the storage resources.
