You can configure FC and FC-NVMe SAN hosts with single nodes through one or more fabrics. N-Port ID Virtualization (NPIV) is required and must be enabled on all FC switches in the fabric. You cannot directly attach FC or FC-NMVE SAN hosts to single nodes without using an FC switch
Configuring FC adapters for initiator mode: You can configure individual FC ports of onboard adapters and certain FC adapter cards for initiator mode. Initiator mode is used to connect the ports to tape drives, tape libraries, or third-party storage with FlexArray Virtualization or Foreign LUN Import (FLI).
How FC target nodes connect to the network:
Storage systems and hosts have adapters so that they can be connected to FC switches with cables.
When a node is connected to the FC SAN, eachSVMregisters the World Wide Port Name (WWPN) of its LIF with the switch Fabric Name Service. The WWNN of theSVMand the WWPN of each LIF is automatically assigned by ONTAP..
Note: Direct-connection to nodes from hosts with FC is not supported, NPIV is required and this requires a switch to be used.
