医院网络异地容灾软硬件及服务器虚拟化设计

该文探究医院网络异地容灾系统的软硬件设计与服务器虚拟化设计方法。该文首先概述异地容灾系统的整体架构,从系统服务器、光纤SAN网络系统、存储系统等方面,介绍硬件设计内容;从灾难检测模块、同步复制模块、灾难切换与系统恢复模块,介绍软件设计内容。随后使用VMware软件,对医院网络异地容灾系统的物理服务器进行虚拟化设计。结果表明,进行服务器虚拟化处理后,不仅能够降低硬件配置经费、提高资源利用效率,而且还能实现灾难的超前识别和备份数据的快速恢复,保证医院业务的连续性。

This paper explores the software and hardware design and server virtualization design method of remote disaster recovery system in hospital network.This paper first summarizes the overall architecture of remote disaster recovery system,introduces the hardware design content from the aspects of system server,optical fiber SAN network system,storage system and so on,and introduces the software design content from disaster detection module,synchronous replication module,disaster switching and system recovery module.Then the physical server of the hospital network remote disaster recovery system is virtualized by using VMware software.The results show that the virtualization of the server can not only reduce the hardware configuration funds and improve the efficiency of resource utilization,but also realize the advanced identification of disasters and the rapid recovery of backup data,and ensure the continuity of hospital business.
