The construction of campus information system mainly includes three functions: campus communication network, library information system and campus card system. The function of campus communication network is relatively complex, involving information resources sharing systems in various fields, such as scientific research, academics, software, economics, politics, etc., personnel management, financial management, educational administration management, scientific research management, file management, foreign affairs management, medical management, logistics Management and other school information management systems and MAIL systems. Different applications have different requirements on the server. Therefore, Inspur recommends that each unrelated application service be deployed separately to obtain better performance and convenient management and maintenance. The data of campus management application is very important for the overall teaching and operation of the school, and it puts forward high requirements for the high availability, manageability and data security of the storage system. The library information system mainly refers to the electronic library system, which is currently two sets and will continue to be expanded in the near future. According to the unique characteristics of e-books and the number of students on campus, the application server performance required by the library information system is quite high, and the storage of book documents also puts forward greater requirements for the capacity space of the storage system to protect the library collection of electronic documents Expansion needs. The campus all-in-one card system can be used by students to handle chores, buy food, drinks, books, and borrow books. The card is not only convenient for everyone to use, but also an important symbol of the school's informatization level. This system not only requires absolute accuracy and security of data, but also requires 24-hour work, and has high requirements for stability, reliability, parallel processing, and network performance.

The backbone uses a Gigabit / 100M Ethernet network, and the storage uses an independent storage area network (SAN) to achieve independent storage and management of data. The server required by the campus computer network is connected to the optical fiber storage system through the SAN switch. The library system server and the card system server are also connected to the storage system through this switch. Each server is connected to two SAN switches through two lines, and Inspur Yingxin EMC CX500 storage system is connected to two switches through four lines. Because the data of the card and some school information management systems are particularly important, in order to be foolproof, Inspur ’s Storage experts recommend that an ADIC Scalar 24 LTO tape library be used for offline backup of such critical data to ensure that the entire campus information system has certain disaster tolerance capabilities. (Because of its own characteristics, the tape library is connected to the main SAN switch by a single line, and is managed and accessed by the backup management server).
