典型的高可靠性服务系统,一般采用集群冗余备份和高性能的磁盘阵列统一存储.但是存在成本较高的问题,一般中小型企业和单位难以承受.针对这一问题,提出一个方案,仅使用两台普通PC Server,没有高性能的磁盘阵列,每台服务器都充分应用,通过数据库同步,智能数据库访问层,心跳检测,当其中一台服务器出现异常时,能够自动无缝地切换到另一台服务器.

Typical service system of high reliability generally uses Cluster and Disc Array, but it is too expensive to Small and medium-sized enterprise. A new scheme is proposed, it uses only two PC Server without Disc Array, through database synchronization, intelligent database access layer and heartbeat detection, when one PC Server failed it will automatically switch to another one seamlessly.
