服务器虚拟化在医院信息化系统中的研究与应用

Research and Application of Server Virtualization in Hospital Information Systems

随着医院信息化建设的不断深入,医院信息系统也越来越多,软硬件部署环境也越来越复杂,如何有效地管理大量的物理服务器是当前面临的问题之一。在对医院信息系统服务器物理部署架构和虚拟化部署架构分析的基础上,对两种部署方式进行了比较,提出了基于服务器虚拟化的混合架构,将业务量大数据访问频繁的关键核心应用部署在物理服务器集群上,将业务量小数据访问频率低的非核心业务部署在虚拟机服务器上,有效地发挥两者的优势。结合医院信息化的实际情况,通过ORACLE RAC技术和vSphere软件在医院信息系统中进行了实际环境下的服务器混合部署,为医院信息系统的高效运行提供了保障。

With the further development of hospital information construction, more and more hospital information systems are being built, and the software and hardware deployment environments are even more complex. Currently, how to effectively manage a large number of physical servers is one of the problems to be solved. Comparing the two deployment methods based on the analysis of the physical deployment architecture and virtualized deployment architecture of the hospital information system server, a hybrid architecture based on server virtualization is established to deploy the key core applications on physical server cluster and non-core applications on virtual machine servers. It effectively takes the both advantages. Combined with the actual situation of hospital informatization, the ORACLE RAC technology and vSphere software are used in the hospital information system to carry out the mixed deployment of servers in the actual environment, which provides a guarantee for the efficient operation of the hospital information system.
