Combining the advantages of the network and virtual SAN technology, the paper focuses on the characteristics of spatial data storage, by proposing a virtual SAN-based architecture of grid GIS data storage. Meanwhile, its corresponding experimental system has been designed to verify this proposal. In order for the storing facilities, FC and iSCSI data based double-thoroughfare have been designed in the proposed system to fulfill the efficient storage and retrieval of huge amount of spatial data. This solution possesses certain practical and applicable values from realizing and serving a technol...
