A group could set up a dedicated server machine (a PC) that communicated with other groups' server machines (either on the same LAN or through switched networks).
一个组可以设置一台专门的服务器(PC)和其他组的服务器通信(可以在同一个LAN中，也可通过交换网络)。
Since all LAN traffic is switched, this is the highest-performance and lowest-cost option.
由于全部LAN流量都是交换的，所以这是一个性能最高、成本最低的选择。
In this scheme, the database nodes can be distributed in WAN or LAN and switched transparently to user applications and the system's disaster recovery time is short and the cost is low.
该方案中各节点数据库可以分布于wan或LAN中，对客户应用实现透明切换和数据的自动同步，系统恢复时延很短，开销较小。
