医院信息系统存储技术及容灾方案的应用研究

Application Study of Storage and Disaster Recovery Scheme for Hospital Information System

目的构建SAN(存储区域网络)架构的数据存储系统,确保医院信息系统(HIS)安全稳定运行。方法针对HIS对网络存储新的发展需求,配置双存储磁盘阵列柜,采用服务器双机集群方式,构建SAN架构的数据存储系统;设计基于虚拟带库对医院两类不同应用数据库(SQLSERVER 2005、ORACLE10G)的容灾恢复系统。结果设计方案的实施达到了数据安全存储和应用容灾的效果,确保医院的各种信息应用安全高效。结论该架构提高了HIS的可靠性和可用性。

Objective To ensure the safe and stable operation of the hospital information system （HIS） by building a SAN（Storage Area Network）-based data storage system. Methods For the new development needs of HIS for network storage, the data storage system based on SAN is built with dual storage disk array and trunked mode of dual server machines. The disaster recovery system is designed for two different application databases （SQL SERVER 2005, ORACLE10G） based on virtual tape library. Results The design can store the data safely and recover disaster, ensure the safety and efficiency of information applications in the hospital. Conclusion The design improves the reliability and availability of the HIS.
