BIG-IQ Centralized Management
BIG-IQ in an auto failover HA configuration with a floating IP address
The BIG-IQ currently managing all BIG-IP devices.
The standby BIG-IQ that has the same configuration as the active BIG-IQ. The standby BIG-IQ automatically becomes active if the active BIG-IQ fails over.
A quorum data collection device (DCD) makes the deciding vote for which BIG-IQ will become active if communication is disrupted between the components of the BIG-IQ high availability configuration. If the quorum DCD is able to communicate with one of the BIG-IQ in the pair during the disruption, that BIG-IQ becomes active. The quorum DCD is not a peer BIG-IQ in an HA configuration.
