Design on High-Reliability Key Hospital Database Server System of "No.1 Millitary Medical Project" / 医疗卫生装备

ABSTRACT

Objective To improve the reliability of the core database system by ameliorating the scheme of the server system architecture. Methods Combined with practice of the hospital informatization, the security and potential hole of the database server system were analyzed and evaluated. Results Aimed to deal with the security hidden-trouble, a mini-server was adopted instead of PC server, while SAN(Storage Area Network) was utilized instead of RAID-5, and mirror copy technique was used to implement the real-time hot copy of the data. Conclusion Consequently the reliability of the system has been greatly improved.
