Date Centre and Virtualization Technology

虚拟化网络技术是指在一个物理网络上同时运行多个互不干扰的逻辑网络,各个逻辑网络都各自有着特定的拓扑及路由算法。通过对网络设备的虚拟整合,实现网络流通量路径的分离,完成网络路径的虚拟化,提高关键业务在虚拟化网络中的服务保障。服务器虚拟化技术通过运用虚拟化的技术充分发挥服务器的硬件性能,能够在确保企业投入成本的同时,提高运营效率,节约经济成本和空间浪费。文中对虚拟化的网络技术进行了介绍与分析,介绍了虚拟化网络技术的概念及原理,讨论了VMware esxi服务器虚拟化、VMware vSphere关键技术,及实现服务器虚拟化所需要的主要组成元素及技术。

Network virtualization technology refers to multiple non-interfering logical networks synchronously running on the same physical network, while each logical network has its own specific topology and routing algorithm The virtual integration of network devices contributes to separation and virtualization of network paths, as well as the improvement for service assurance of key services in virtual network. The server virtualization could bring into full play the hardware capability of servers, ensure that the enterprises could consider the improvement of operation efficiency, and save economic cost and space while making investment This paper introduces and analizes the network virtualization technology, then describes its concepts and iples, and discusses the virtualization of VMware esxi servers, the key technology of VMware vSphere, ding the major factors and technologies for realizing server virtualization.
