网络服务器容灾技术应用研究

容灾技术通过建立异地灾备中心,提供一个防止用户业务环境系统遭受各种灾难性破坏的信息系统,使其具备在灾后快速恢复的能力,能满足信息系统业务连续性需求。本文首先对几种容灾技术进行比较并展开深入研究,简要分析了容灾技术的评价指标以及目前常用的容灾技术—IPSAN的技术原理。最后,论文针对南京工程高等职业学校网络服务器进行容灾方案的整体设计。

Network Server Disaster Recovery Technology Application Research

Disaster recovery technology through the establishment of remote disaster recovery center,provide a means for preventing user service environment system subjected to various disaster destruction of information system,make its have in post-disaster recovery ability,can meet the needs of information system business continuity.Firstly,several disaster recovery technology for more in-depth research,a brief analysis of the disaster tolerance technology evaluation index and current disaster tolerance technology-the IP principle of SAN technique.Finally,aiming at the Nanjing engineering higher occupation school network server disaster recovery scheme for the overall design.
