Design And Deployment Of Campus Network Data Center Solution

With the development of the information construction in colleges,the data center needs to deploy more and more information systems.Campus network users are also dependent on information services in the teaching,scientific research,life and other aspects.The data center is faced with the problems such as the lack of redundancy network architecture,the difficulty of infrastructure resource management and the lack of remote access security.How to solve these key problems of data center is an important part of campus network information construction.By analyzing the main problems of data center and the current situation as well as development trend of the technology,this paper identifies the main needs of the data center construction in next step.Through the research on the OpenStack,this paper puts forward a cloud platform based on OpenStack.This platform can manage the data center resources and improve the efficiency of data center resource utilization.In this paper,we designed a data center network redundancy architecture to provide a more reliable and stable network infrastructure for the services running in the data center.We set up multi-export redundant network architecture,so that campus network users can access network resources in a variety of ways,and enhance the reliability of export network.In order to alleviate the shortage of public IP address we put forward a model to access the service resource based on front machine architecture.Based on the characteristics of university campus network users and resource access requirements,as well as the security sensitivity of data services,this paper proposes a scheme for the campus network users to access the data center.Relying on the multi-campus security interconnection and remote access needs,we research the network connection between the main campus and branch campus and remote access of mobile office staff to main campus as well as the secure interconnection mode between the main campus and university partners.By using IPSec VPN,L2 TP over VPN and firewall technology,this paper proposes a data center remote access scheme,which improves the security of data center access and enhance the resource access experience of users outside the campus network.The overall solution of this data center not only solves the key issues the traditional data center is currently facing,but also has a good extendibility.This program can be well adapted to the needs of the development of information technology for a long time.The successful implementation of the program can provide an effective reference for other colleges and universities in the construction of data centers.
