Switches help Southeast University connect data centers in multiple campuses

Creating World-class University Informatization is facing new challenges

Promoting campus informatization comprehensively is an inevitable choice for schools to implement the national informatization development strategy. Southeast University is a national key university directly under the Central Government and directly under the Ministry of Education. It is one of China's famous Eight old construction schools, the National "211 project", "985 Project", "excellent engineer Education and Training Program" and "111 plan" are key universities.

Southeast University adheres to the concept of "Educating people first", takes "rejuvenating the country through science and education" as its mission, constantly increases teaching investment, deepens Education and Teaching Reform, and is committed to building an internationally renowned high-level research university. In recent years, Southeast University has increased its informatization efforts and achieved significant progress in improving the school's teaching, scientific research, management, and service, it has effectively promoted the further improvement of School Informatization Construction.

At present, with the continuous development of information construction, the degree of information technology on campus is constantly improved, and the dependence on IT systems is getting higher and higher. The business system continuity and the importance of disaster protection are becoming more and more prominent, they all put forward high requirements on the bandwidth and reliability of the data center network.

With the gradual expansion of the school scale, Southeast University has established two data centers in the four-card building campus and the jiulong Lake campus, where different services are deployed and all servers are virtualized. How can we ensure business continuity in the face of numerous business systems and current multi-data center construction? How can we continuously and smoothly Promote School Informatization? The campus informatization of Southeast University is facing new challenges.

To meet the needs of Southeast University,  conducted in-depth research and analysis on Southeast University to design a network architecture featuring high availability, scalability, ease of management, and security and reliability. All blade servers in the two campuses of Southeast University have been virtualized using VMware, And the campus access authentication is performed on MX900. The Internet egress of the two data centers is located at the campus of the Four-card building, and the two campuses are connected through optical fiber cables. Data Centers are interconnected through EVN and a large Layer-2 network is built to achieve unified business scheduling between data centers and achieve high reliability and Business Continuity of multiple business systems. In addition, virtual machines are freely drifting, it lays the network foundation for business-level dual-active or even multi-active data centers in the future.

uses the CE12800 with high bandwidth, low latency, and the highest density of 10GE, 40GE, and 100GE boards to provide customers with a future-oriented core network for large bandwidth and low latency data centers. In addition, CE12800 has rich data center features, such as TRILL, FCoE, DCB, and Virtualization (CSS and ), this solution provides customers with scalable and stable data center network solutions for the next 8-10 years. With the EVN technology, multiple data centers in Huaneng can be interconnected, A Distributed Remote Interconnection layer 2 network is built to realize the distribution of resources in different regions and unified dynamic scheduling, which enables unified management and improves disaster recovery redundancy through distribution.

At the same time, is actively building the cloud computing data center ecosystem with an open mind. IT has cooperated with a number of world-renowned IT vendors and standard organizations, its Cloud Fabric2.0 "Cloud connection" solution implements open connection with the VMware Cloud management platform vCloud and the network virtualization platform NSX to jointly create an online network policy migration solution, it helps Southeast University achieve unified and automatic distribution of ICT resources.

Provides stable solutions to create a secure network environment

 is committed to providing customers with a safe and secure network environment with first-class data center-level core equipment.

In addition, you only need to replace the equipment supporting EVN technology at the data center boundary, and do not need to change the internal network structure of the existing data center. This effectively protects the existing network investment of Southeast University and reduces the changes to the existing network topology.

At the same time, the data center-level Core switch CE12800 has a large capacity (supporting 10GE/40GE/100GE line cards) and a wide range of data center features (such as TRILL and EVN) the industrial design can effectively protect users' investment (most of the components of CE12800's full range of devices can be used in general), and provide users with a stable network architecture for the next 5-10 years.
