服务器虚拟化技术及其在医院的应用

摘要

The server virtualization is a technology to integrate all physical server resources as one logic unit,and then to divide it into isolated virtual servers-virtual machines-as needed.Server virtualization technology has been widely used at home and abroad.And its application in the hospital is gradually widened.Integration and virtualization of servers make it possible to reduce the number of physical servers so as to improve resource utilization significantly,deploy servers rapidly,realize high availability of the hospital information system,ensure continuity of hospital operation and reduce the cost of operation and maintenance.The effective combination of server virtualization,storage virtualization and network virtualization highlights the significance of virtualization.%服务器虚拟化是把物理服务器的资源抽象整合成一个逻辑资源,然后虚拟成多台相互隔离的虚拟服务器即虚拟机.服务器虚拟化技术在国内外已被广泛应用,在医院的应用正逐步深入.通过服务器整合和虚拟化,控制和减少了物理服务器的数量,明显提高资源利用率,并可快速部署服务器,实现系统的高可用性,保障医院业务的连续性,同时降低运维成本.把服务器虚拟化和存储虚拟化、网络虚拟化有效融合,更能彰显虚拟化的价值.
