Virtual SAN-based Data Storage Method in Grid GIS

The objective of this paper is to discuss the efficiency storage of mass spatial data in grid GIS environments. This paper introduces a grid GIS data storage solution based on the integration of the advantages of grid and virtual SAN techniques. This solution is a milestone for the presence and future of GIS, aiming at seamless and high efficiency storage management and data service. Then this paper discusses the structure of experimental platform, the realization of the data service, and the advantage of this method.
