In information warfare (IW), information storage is one of important processes to obtaining information dominance. Existing military storage systems are mostly independent, so they can?t provide reliable and effective storage service for users. How to integrate existing military storage systems into a network storage system which have stronger compatibility..higher usability and better cooperation? It?s the problem urgently need us to solve. The article makes a detailed introduction to technologies of storage virtualization (SV). As to its different realization methods, we analyze both their advantages and disadvantages. In the paper, the conception of integrating military storage resources based on SV is proposed.
