[Abstract]:The development of network storage technology is very fast. The traditional data center architecture based on DAS,NAS,SAN storage architecture can not adapt to the development of campus information. Therefore, it is necessary to build a high performance data center storage system to ensure that the system continues to work all day long. Sichuan Postal and Telecommunications Vocational and Technical College is a provincial model vocational college facing the communication industry in southwest China. At present, the data center is still built around the structure of the server, the educational administration system and other application systems are installed on a server. The server not only runs the application system, but also produces local data storage. Although most of the current needs can be met, there are still: no centralized storage devices, high risk of single machine failure; serious waste of storage space, data can not achieve simple security sharing; there is no snapshot backup and recovery mechanism based on time point; The geographical location of each laboratory is scattered, which fails to form an organic whole, and the information island can not realize the centralized data transmission, storage and management. In order to solve the problems existing in the campus network data center, this paper proposes a storage architecture solution based on IP-SAN. On the basis of detailed and in-depth analysis of the theory of IP-SAN,iSCSI technology, from the perspective of storage system architecture and requirement analysis, the business requirements of storage network are fully considered, and the planning and design of data center network are given. Construction and post-testing for in-depth and comprehensive analysis and research. The main contents are as follows: firstly, this paper analyzes the current situation of the data center architecture in colleges and universities, and discusses the development course, analysis and research of the storage technology. At present, as a popular storage technology, IP-SAN is also widely used in the data center storage system of colleges and universities. The research focuses on the data center storage system IP-SAN architecture and the principle of iSCSI protocol. Then the data center storage system, the structure and principle of the system hardware platform are studied, and the reasonable hardware system scheme is adopted. Plan device hardware, determine storage device, switch and server device model and quantity, hardware configuration. The hardware connection and network structure of the storage system architecture. Then the network architecture of storage system (based on IP-SAN) is studied in detail, and the selection of hardware equipment is completed. Through the storage management system to manage storage resources and reasonable allocation of data services. And provides the suggestion, involves the later data center upgrades the reserved space, guaranteed the sustainability input, the application. Finally, the problems and faults found in the network debugging and data service operation under the IP-SAN framework are studied, the problems are analyzed, the solutions are put forward, and the experience of operation and maintenance is accumulated in the practical application process.
