Teaching system, Dawning Server has built a complete campus server system for Jinan No. 1 Middle School with its high-quality products and services, as well as its rich experience in serving the education industry for many years, helping Jinan No. 1 Middle School to realize the application of campus network and multimedia teaching.
Change according to needs, build an information campus
Founded in 1903, Jinan No. 1 Middle School in Shandong Province is a provincial key senior high school with a century-old history. Excellent talents with outstanding talents also have a certain reputation in the world. As a century-old school, Jinan No. 1 Middle School has written a deep stroke in the development of China’s education industry. However, with the development of the times, the environment of the entire education industry has changed. How to maintain the competitiveness of the century-old school and rejuvenate it in the new era has become a major concern of the leaders of Jinan No. 1 Middle School. In recent years, with the development of informatization, Jinan No. 1 Middle School deeply felt that informatization is the only way to realize the modernization of education, and the introduction of information technology into the campus is a necessary condition for improving the comprehensive strength of the school. Therefore, it attaches great importance to the construction of campus informatization.
Under the leadership of the Jinan Municipal Government, the relocation project of Jinan No. 1 Middle School was officially launched in 2006. In March 2007, Jinan No. 1 Middle School moved into the new campus of the former Shandong Institute of Light Industry. The new campus of Jinan No. 1 Middle School is the leading project of the Jinan education system integrating the city’s educational resources. In the construction of the new campus, both the Jinan Municipal Government and Jinan No. 1 Middle School regard the campus network and multimedia teaching system as the top priority of the entire project, and Bao Zhiqiang, the former mayor of Jinan City, personally led the supervision of the expert group of famous universities in the province.
The information center construction of Jinan No. 1 Middle School is based on the standards of colleges and universities. In addition to serving as the network platform of the multimedia teaching system, it also needs to provide functions such as mail reception, data storage management, billing gateway management, and teaching development. The only outlet with China Education Network and Internet Network. Such a variety of tasks require powerful computing power and data storage capabilities, which cannot be borne by a few PCs. Therefore, Jinan No. 1 Middle School clearly proposed the selection of high-performance servers as the hardware platform of the campus network. Software and hardware devices are required to have high operating efficiency, fast response speed, good compatibility and scalability. In hardware, servers are required to use processors that support 64-bit and 32-bit compatibility, and perform cluster and load balancing for servers. , the requirements are more stringent.
Flexible configuration to build an efficient platform
After in-depth research on the application of Jinan No. 1 Middle School Information Center, the technical staff of Dawning Company found that although Jinan No. 1 Middle School is a middle school, its campus network construction cannot be based on the traditional middle school campus network due to its high starting point. In addition to satisfying high reliability functions, the construction of the system should also have features such as advanced nature, high performance, and linear expansion, which can meet the current and future business development needs of the system, as well as the rapid growth of the market economy. Therefore, Dawning Company proposed a cluster plan composed of minicomputers and high-performance servers to provide power for the school’s information center. All-in-one card, e-mail, teaching development and other tasks are realized by different servers, so as to improve the work efficiency and efficiency of the information center. stable operation of the system.
The core application service is the top priority of the campus network construction of Jinan No. 1 Middle School. A large number of educational and teaching software resources, administrative information, office information and other data materials will be stored in the database. These information will be dynamically released through the Web server. Users can query the information in the database through browser or client software, therefore, the system needs to be able to run stably for a long time. Dawning used two EP430 Tianyan second-generation minicomputers in the system construction to form a dual-machine hot backup system. When the working machine is abnormal and cannot support the operation of the information system, the backup machine will take the initiative to manage the work of the working machine and continue to support the system. operation, so as to ensure the continuous operation of the information system. At the same time, considering the expansion and upgrade capability of the system, the EP430 Tianyan second-generation minicomputer adopts an open x86 architecture design, which is an application-level minicomputer with good cost performance. It combines high performance, high scalability, large capacity storage and high reliability. Integrated, fully capable of 64-bit SMP development and testing, scientific computing, background database, background storage and other applications, providing an excellent smooth upgrade capability for the system.
Jinan No. 1 Middle School Information Center is composed of database, WEB/DNS, billing gateway, mail, mail gateway, VOD, teaching development, anti-virus, FTP, backup/firewall log, e-book, e-journal server and other applications. The information center has a wide variety of applications and comprehensive consideration of future scalability, security, ease of maintenance and initial capital investment. The construction adopts the cluster model based on the IA architecture, and a separate server system is configured for each application. This improves the application effect of the entire system. Dawning Company adopted Dawning Tiankuo I450r-F dual-channel dual-core server and R4280AD four-channel dual-core server in the system construction of the information center to form the cluster server system of Jinan No.1 Middle School Information Center, including mail, mail gateway, VOD, teaching development server The server adopts Dawning R4280AD; WEB/DNS, billing gateway, antivirus, FTP, backup/firewall log, e-book, e-journal server and other servers adopt Dawning Tiankuo I450r-F. In addition, according to different application characteristics, Dawning also provides targeted solutions, such as teaching video playback, e-learning development, etc. These functions are an important part of multimedia teaching, and have high performance requirements for servers. At the same time, huge storage space is needed. In response to this demand, Sugon connects the server to the SAN storage system through Fibre Channel, and realizes the dual-machine redundancy function through software. When working normally, it provides VOD and educational services to the outside world. When a server appears In the event of a failure, another server can take over the tasks on the failed server to provide external services.
It is worth mentioning that in the whole system construction, the design of the data storage system is very good. This program adopts the latest SAN structure data backup technology. The DS8340 series of products are used as the centralized storage device of the network storage system, which supports online capacity expansion, ensures data integrity, and reduces the risk of system downtime. It is backward compatible with Sugon’s existing 2Gb optical disk expansion cabinet, and can directly connect the 2Gb optical fiber expansion cabinet to the DS8340 controller without changing or rebuilding any configuration or data files to achieve “seamless data migration”, which is well guaranteed The storage management of the campus database provides a good support for multimedia teaching.
Conclusion:
The competition in the 21st century is the competition of talents, and the competition of talents is actually the competition of the education industry. Nowadays, the degree of informatization construction has become an important criterion for measuring the modernization of a country’s education.
