摘要
介绍一种支持电网调度高可靠性要求、用于监控与数据采集(SCADA)的双机共享磁盘冗余阵列系统的实现方法,通过双机监控程序监视本机应用程序系统,实现主备机自动、手动切换。使用共享磁盘冗余阵列,保证了数据的一致性。在此方案下,还可以对应用模块进行切换,并实现数据库系统的容错。最后对这种方案进行了评价。
To meet the high reliability requirement of power dispatching, a method of implementing the dual processor system in SCADA with shared RAID is put forward. Each processor is monitored by the dual processor monitoring program, so that the auto-switch and manual-switch between the host and the standby processor can be realized. Data consistency is achieved by shared RAID and the switch between different application modules and fault tolerance capability of the database system are also realized. Finally, the performance of the scheme is evaluated.
