Automated failover and switchover

The business must define how much control is given up to automation during unplanned outages. IBM® i high availability solutions have a customizable level of business interaction in failover processing. In case of a failure, the application can automatically failover to a backup system, including all application environment start.

Some customers want control over the failover processing. In this situation, the system will require a response for failover processing to occur. In a solution where user interaction is needed for failover, the think time (or time taken to make a decision to failover) is directly charged against the recovery time objective. The business must decide how much automation control will be given to the system during failover. The business should not take more time to make the decision to failover to the backup system, than it takes to actually do the failover.
