The controller object is the physical fibre-channel interface port on the server that operate as FC targets. It is identified by the name fc0 ... fc<n> on FC only server and on both FC & iSCSI server it starts from fc1. For iSCSI operation it is referred by the generic name `iscsi' to represent all the physical ethernet interfaces. Know controller interface types is listed below
iscsi | Any network interface recognized by kernel. More control over specific network by specifying iSCSI portal tag and name. |
fcn | Selects the fibre channel target port as specified by the instance number n |
nvmet-rdma | Any RDMA transport registered with the kernel. Typically they can be Infiniband, iWARP, or ROCE |
nvmet-fc | Uses the NVMeoF transport provider over Fibre-Channel |
nvmet-tcp | This uses standard TCP network interface just like iSCSI |
