With the rapid development of computer technology, data storage in the modern information systems playing an increasingly important role. It is important for various types of applications to provide reliable and efficient operation of security. How to ensure the safety of the core data to ensure that the information system's high availability and high performance, has been the building of modern information systems is an important topic. In this paper , on the basis of the structure of the storage system related research, and investigate and participated in the building of a storage system for the base of practice. I summed up the situation for several different models. Specific and practical application are given in the research and design examples. This paper review on the concept of storage area networks, aracteristics and the current applications, such as the challenges faced by the problem of the storage network the forefront of technology and development trends are presented. Combination of many factors, analysis the demand of the storage systems and the requirements of security for the further application in the model design and lay the foundation for achieving. With DAS, NAS, SAN three storage architecture advantages, in different circumstances, the characteristics and applications. Two proposed generic storage model were put forward. Finally the actual projects have been completed and conduct a detailed study. To further promote the application of this system paves the way for the development of storage systems with a new idea.
