摘要
目的:探讨组建提高医院信息系统核心服务器稳定性、可靠性、安全性的系统架构。方法:客观分析医院服务器系统采用"PC服务器+本地硬盘"模式存在的一些安全漏洞,提出基于集中存储的双机热备方案和基于"小型机+磁盘阵列"全冗余模式的方案。结果:基于"小型机+磁盘阵列"全冗余模式,理论上可行,实践上可用。结论:"小型机+磁盘阵列"全冗余模式,可以有效提高核心服务器系统的稳定性、可靠性、安全性。
Objective To discuss how to improve the stability, reliability and security of the core servers of hospital information system. Methods Flaws on security were analyzed objectively in hospital server system adopting ＂PC server ＆ local hardisk＂ scheme. New schemes were put forward including both hot standby scheme based on concentrated storage and full redundancy scheme based on ＇minicomputer ＆ diskette array ＇. Results It is proved that the full redundancy scheme is reasonable in theory, and usable in practice. Conclusion The mode of ＇minicomputer ＆ diskette array＇ can effectively enhance the stability, reliability and safety of core servers.
