Abstract
Failover subsystem of computer consists four modes In this paper, These modes will be discussed in more detail. - dual computer mode - failover mode - single computer mode - standby synchronization mode we have suggested the method of dual/redunancy configulation of server computer. Failover is activated by the standby computer, active computer receives a failover request across the inter-computer link immediatly. The active computer controls the scada system and maintains the current state in it's data base and channel system safety.
