Beijing Union University is a municipal comprehensive general higher education institution officially established by the Ministry of Education in 1985. It was developed along with the needs of economic construction and social development in the capital with reform and opening up. The school faces the economic construction of the capital, adheres to the higher vocational education, general higher education, adult higher education overall planning, coordinated development of the school direction, faces high and new technology and the tertiary industry, focusing on the development and construction of Beijing ’s economic construction and social development. Disciplines and majors, with 9 disciplines and 91 undergraduate majors, the most comprehensive disciplines in municipal municipal universities, the largest number of majors, close to the needs of Beijing ’s economic construction and development, and has a number of provincial and ministerial levels A university with a key major. The school is the fastest-growing and largest municipal university since Beijing ’s reform and opening up. It currently has more than 30,000 students, including 13,800 full-time undergraduates, more than 8,300 vocational college students, and nearly 10,000 adult students. People (including adult education and self-examination education). With the rapid development of the school and the widespread application of network technology, multimedia technology, and storage technology, the School of Applied Technology of Beijing Union University is preparing to build a campus backbone network for the new campus. The entire network will complete information management and exchange within the campus. Students and society provide an interactive platform to provide students with convenient conditions for learning, provide perfect content for students' daily lives, and provide teachers with rich resources for teaching. The successful application of the backbone network will play a good role in promoting the school's teaching, scientific research and active academic atmosphere. Campus backbone network construction principles The campus network is a comprehensive digital network that meets the needs of multimedia information such as digital, voice, graphics and images, and the transmission and processing of comprehensive scientific research information. It is the foundation for the deep development of the Internet application of the school. It is also the school ’s modern school running and teaching, strengthening management, The need to achieve scientific research. In order to achieve high performance, high availability and easy management of the backbone network, the following design principles are followed in the technical design: 1. Processing capacity A powerful hardware platform and advanced Itanium 2 technology are used to make the system have powerful processing capacity and expansion performance to meet the needs of existing business and future business development. 2. Advancement Advanced design ideas and technologies are used for system design, and the products and technologies included adopt advanced, mature and reliable technologies. 3. Reliability and availability Select a highly reliable network platform, hardware platform and software system. The entire system platform has extremely high reliability and availability. 4. Openness Choose open products that comply with industry standards, management, maintenance and upgrade are very simple, greatly reducing the total cost of ownership of the system. 5. Security The interconnection between internal networks, internal networks and external public networks, use VLAN / ELAN, firewalls, etc. for access control to ensure network security. 6. Practicability The design of the entire system fully reflects the practicability of the system in terms of performance and price ratio. It should not only adopt advanced technology, but also achieve the goal of campus network under economically allowable conditions. System network topology The above picture is the campus network topology map. The content publishing system mainly relies on the three-tier Internet computing model, which is composed of a WWW server and a database server. The WWW server mainly provides Web page browsing and school information publishing services. The page click rate is high, which requires the CPU's computing power and data I / O capabilities to be very good. In the program design, we adopted the latest Itanium technology, which not only meets current business needs, but also meets future business needs. Expand. Inspur Yingxin SP3000 adopts the latest technology in the industry, based on 64-bit Intel Itanium 2 processor and a new system architecture, SP3000 adopts symmetrical and modular design, supports 4 Itanium 2 processors, system bandwidth up to 6.4GB / S, can Handle complex data analysis. SP3000 supports ECCDDR memory, with a maximum capacity of up to 32GB, integrated dual-channel Ultra320 SCSI controller, disk read and write speeds up to 320MB / S, and all key components such as hard disks, power supplies, fans, PCI-X, etc. use hot-swap technology to facilitate the system The maintenance and management of the company, in conjunction with the Falcon server management software enterprise version independently developed by Inspur, can effectively save user investment and improve work efficiency. For the database server, we adopt the high-performance, high-reliability and high-availability four-channel enterprise server Inspur NC2000, and configure 5 hot-swap SCSI hard drives to do RAID5 to protect critical data. As a campus network data center, it meets the needs of the entire school. Data requests for teaching, office, management and other business, store key data and information of the school, non-stop to provide a full range of database services for students and faculty, and can easily withstand sudden concurrent access. The school's OA server will meet daily office services, such as word processing, table making, official document circulation, meeting arrangement, course arrangement, etc. At the same time, teaching management, student management, file management, etc. must be implemented, so the processing capacity and memory of the server Speed ​​and size, system bus speed and bandwidth, disk system I / O capabilities, and network I / O capabilities are all relatively high. We selected Inspur NC2000 enterprise server in the solution selection. Inspur Yingxin NC2000 adopts optimized architecture and supports four XeonMP processors. The processor's three-level cache can be up to 2MB, and the maximum can be expanded to 24GB ECCDDR memory. It supports ChipKill technology, MemoryScrubing and other advanced memory error correction technologies, integrated dual-channel U320SCSI controller, can increase the read and write speed of the hard disk from the original 160MB / s to 320MB / s, integrate 1 Gigabit and 1 100M dual network card, support advanced network Features, improve the transmission efficiency and security of the network, the maximum can be expanded to 10 hot-swappable hard drives, the maximum storage capacity is nearly 1.5TB, and key components such as system fans and PCI slots support hot-swap technology, which improves expansion and maintenance The convenience of the system effectively guarantees the stability, reliability and efficiency of the system.
