Redundant (Fault Tolerant) Configuration
Note: This feature is not supported on the APM E2000.
Heartbeat, Redundancy, Data Synchronization, and Failover support provides the ability to back up and restore an APM 2500 or APM 5000 system with little or no downtime in the event of a failure of a primary APM. By using the heartbeat protocol in conjunction with network RAID, a redundant APM automatically takes over device and console management in the event of a failure of the primary APM or its Ethernet connection.
A heartbeat signal between a primary and secondary APM verifies that the primary APM is up and running. If the heartbeat signal is not received from the primary APM for a predetermined interval (5 seconds by default), the primary APM is assumed to be down and the redundant APM takes over. When the primary APM is brought back up, the secondary APM fails back and synchronizes data with the primary APM.
