利用群集和存储区域网技术构建安全的数据库服务器系统

在医院信息系统实际应用中，大多数都配备了专用数据库服务器（DS）。大型医院的HIS系统，因业务数据量庞大需要配置两台或多台DS，满足医院日益增长的数据处理要求。医院的HIS大都采取客户，服务器业务工作模式，其业务数据集中存储在一台或多台DS上。这种单节点服务器模式存在较大的安全隐患，主要探讨利用双服务器群集和光纤存储技术，构建安全的数据库服务器系统及数据存储系统。

Make Use of Cluster and Storage Area Network Technique to Establish the Secure Database Server System

The exclusive DSes are mostly set in the practical application of information systems of hospitals. HIS systems for large-sized hospitals need two or more DSes because of their enormous data flow, to meet the requirement of gradually increasing data processing demand of hospitals. HIS systems in hospitals majorly take use of customer/server operation mode, the business data of which are stored in one or more DSes. This kind of single node server mode is not safe. Our discussion is mainly on the topic of making use of dual-server cluster and fiber storage technique to establish a safety database server system and data storage system.
