Inspur helps Jinan University campus card construction

What should a 21st century campus look like? I am afraid everyone now has their own answer. But there is one thing in common: the modern campus is an information campus. One of the hot topics in the field of campus informatization is the construction of campus card system. Through the small cards, the lifestyles of teachers and students have undergone tremendous changes. At the same time, the information islands on the original campus have also been connected into an organic and efficient whole.

Jinan University, located in the capital of Shandong Province, is a provincial comprehensive university. This famous university was founded in 1948. At present, there are more than 30,000 full-time students and more than 8,000 students enrolled in adult education. At the same time, Jinan University has more than 2,200 in-service faculty and staff, and many more people come to the school to exchange visits and visits every year. Especially in the face of a large number of scholars, how to meet a series of applications such as identity recognition, information query, payment, and access management, and then meet the goals of building a safe university and implementing more scientific management? Jinan University has found a way to solve this problem-the campus card. Recently, the campus card system of Jinan University has entered the implementation stage, and it is expected to be put into use when the new school year begins in September. As an important part of this system, the high-performance storage solution provided by Inspur Storage has also become one of the earliest storage systems used in campus card systems in China.

Campus cards light up campus life

I do n’t know since when, the students ’bags are full of various“ cards ”and“ certificates ”, to withdraw money by credit card, to eat by meal card, to use the“ 201 ”card for calling Documentary evidence, go to the computing center with a computer certificate, exams and exam certificates. The complicated procedures have brought many inconveniences to the lives of the students. In this case, the campus card came into being. At present, the commonly used campus card is made with the help of the campus network and the most advanced non-contact IC card in the world. It integrates document management, student file management, staff and staff attendance, cafeteria management, computer room management and other various service functions. In one, it truly realizes a hand-held card and smooth campus.

The campus card will bring us a new and convenient modern life. School management will be greatly simplified and work efficiency will be greatly improved.

Jinan University constructs a prospective campus card system

Facing the imminence of campus informatization, Jinan University began to realize the dream of a digital campus by building a campus card system. In the planning of Jinan University ’s digital campus, it is proposed that the digital campus will use computer technology, network technology, and communication technology to fully digitize all information resources related to school teaching, scientific research management, and life services, and use scientific and standardized management to these information resources. Integrate and integrate to form unified user management, unified resource management and unified authority control, and build the school into a virtual university that faces the campus and faces the society beyond time and space. In the process of achieving this goal, it is actually a systematic project to gradually eliminate information islands on campus, effectively realize the sharing of data and information, and greatly improve the school management level.

Under such ideological guidance, Jinan University has put forward very high requirements for the information system. First of all, the campus card system is the basic and integrated "campus card" system platform to be constructed for the informationized campus. On this platform, basic subsystems and corresponding applications such as unified identity authentication, school consumption, and school management must be implemented. The second is to truly achieve "one card in hand, travel all over the campus." In the process of further implementation and application, the campus card system of Jinan University also requires the combination of school and bank, electronic money settlement, cardholder self-service deposit, etc., and real-time self-transfer of bank cards and campus cards. The financial function of the campus card.

High standards to promote perfect solutions

In terms of actual needs, Jinan University proposed that the entire system should be coordinated with the original campus network. Because the campus card of Jinan University already involves payment, it has higher requirements for transaction security, not to mention that this system will be required to realize the inter-bank exchange between schools and banks in the future. Therefore, in this system construction, for the application of payment and identity authentication, it is required to build an independent data center to support it, while applications such as non-payment support the original campus network system.

In the construction of the data center, Jinan University proposed to build a "dual-machine system that supports domain division or a 4-node UNIX cluster system." Generally speaking, the amount of data generated in the campus card system is not large, but it has very high requirements for the high availability and high security of the system. In the requirements of this system, it is clearly proposed that the entire system should be equipped with a high-availability environment supporting dual-machine hot backup and a supporting management system supporting a high-availability computing environment. Disaster recovery and backup in different places on campus.

Different from the construction of the previous campus card system, the data center project in the campus card system puts forward clear requirements for storage. In this system, you need:

-Adopt iSCSI storage system

-More than 4 full-duplex 1000BASE-TX interfaces

-Supports jumbo frames

-Support more than 16 logical volumes, RAID5

-Support remote disk protection, snapshot and other functions

-The capacity is around 2TB, supporting high availability features

In addition, for the entire campus card system, Jinan University proposed:

-Supports 200,000 cards and can be expanded according to demand

-The terminal equipment supports 5000 sets

-Full backup of consumption data, consumption flow can query data for one year

-The hardware and software system is based on the campus network layout and supports the requirements of next-generation Internet technology

The campus data center has become prototype

According to the above requirements, Inspur Storage provided the high-performance storage system AS500 based on Inspur's "active storage" concept for this project as the core of the Jinan University campus card data center computing system.

Inspur AS500 storage system adopts a modular design based on an open architecture and incorporates industry-leading industrial standards including iSCSI, FC, SATA, etc. It not only has extremely high scalability, high performance and high availability, but also has good Application flexibility can be used to build various storage architectures such as NAS, FC SAN, and IP SAN. Together with powerful AS Manager storage management software, it can help users to effectively manage information data and achieve a highly available computing environment.

The storage capacity of AS500 can reach 4.5TB. In the case of dual controllers, if the host interface uses iSCSI, the data read speed can reach 335MB / s. In terms of ensuring the high reliability of the storage system, AS500 is "hard and soft". In terms of hardware, AS500 uses a full range of redundancy technology to achieve load balancing and online hot swap. In terms of software, with the help of AS Manager storage management system, AS500 can implement management functions such as snapshot and cache mirroring functions. Once the system fails, you can use snapshot technology to restore the state to a certain point before the failure; the application of cache mirroring technology can ensure that in the case of a controller failure, another controller can use the cached data it is applying Safely save to disk. Under this mechanism, the high standard and high availability requirements of Jinan University are guaranteed.

Topology diagram of Jinan University campus card data center 1

In the topology diagram, we can see that the entire data center consists of 8 PC servers, 2 minicomputer clusters, and 1 AS500 storage system. Among them, the minicomputer cluster and AS500 storage system together constitute a unified identity authentication and consumer transaction management platform. All systems are interconnected by Gigabit Ethernet to form the entire campus card system.

In practical applications, in order to ensure high security, the Jinan University campus card system for financial transaction data uses a VPN private network + security strategy to fully guarantee the transaction security of the entire system. It is used for financial transaction networks and non-financial transaction networks. It is actually discrete.

Digital campus digital life

Right now, the campus card project of Jinan University has entered the final sprint stage. At present, the initial card issuance volume of the entire system is about 40,000, and the MF1 contactless logic encryption card, which is the most widely used in the field of contactless IC cards and the most cost-effective, is adopted as the application carrier. Starting from September, teachers and students of the whole school can hold a campus card to realize consumption in canteens, water rooms, bathrooms, merchants, etc. At the same time, libraries, computing centers and even exams will be able to "one card pass". Gone are the days when card piles and card troubles are gone.

In the second phase of Jinan University campus card construction in the future, after the school-bank interconnection is successfully implemented, Jinan University campus card can also realize the loading function, and can realize self-service through the terminal equipment provided by the bank.

It can be seen that the prototype of the modern digital university has appeared before our eyes.
