随着电大网络教育的发展和基于网络考试课程的推广,硬件投入及系统维护工作量激增,传统的数据中心框架已越来越不适应电大教育和基于网络考试发展的需要. 文章旨在研究利用虚拟化技术降低硬件投入成本和系统维护工作量. 目前,电大考试服务器的利用效率非常低,我们可以通过将现有服务器虚拟化的方法提高其使用效率,并且可以快速部署虚拟考试服务器,从而提升管理维护的便捷度.由于一台物理服务器可以同时安装多个虚拟考试服务器,而每台考试服务器又同时需要连接不同的VLAN网络,这就需要通过设置虚拟交换机的方法实现虚拟网络与现实网络的连接.

With the development of network education at Radio & TV University as well as the popularization of courses based on network examination, there is an sharp rise in hardware investment and workload of system maintenance. It's become harder and harder for the traditional framework of data center to meet the great demands of Radio and TV education and the network-based network examinations.This paper looks into the possibilities to reduce the investment of hardware and the workload of system maintenance by the use of virtualization technology. At present, the examination servers are of extremely low utilization. Therefore, it's quite sensible for us to virtualize the current servers to enhance its utilization, whereby to achieve rapid deployment of servers for examination as well as to promote the convenience of maintenance. Since multiple virtual servers can be mounted on one physical server and each sever can be connected to several different VLAN networks, it's quite possible to interconnect the virtual and physical networks by means of setting up virtual switch.
