You must install X1024 or X1124 Fibre Channel NIC adapters on your storage systems for IP over Fibre Channel functionality.
An X1024 adapter has two 2-GB Fibre Channel ports and an X1124 adapter has two 4-GB Fibre Channel ports.
In the SnapMirror over Fibre Channel application, they run in the switch fabric topology logged in to the Fibre Channel switch as an F-Port. Each port discovers other FCVI-capable ports by querying the switch name server and then logs in to these ports as necessary. Each port is identified by its unique World Wide Name (WWN).
The adapter operates as a standard network interface. Each port must be configured with its own IP address and network mask, just as an Ethernet adapter is configured. For an active/active configuration system, the administrator must also configure its partner IP address.
