Port Redundancy

To allow for port redundancy, two front-end ports on a storage controller must be connected to the same switch or server.

Fault domains group front-end ports that are connected to the same network. Ports that belong to the same fault domain can fail over to each other because they have the same connectivity.

If a port becomes unavailable because it is disconnected or a hardware failure has occurred, the port moves over to another port in the same fault domain.
