Hi suprtbowl100d, I see some confusion here .. You may need physical ports if FC/iSCSI protocol is used. To use NFS protocol, only nasServer and storage pool should be configured any other ports/iSCSI ports are not required. Also, csi driver uses nasServer and not responsible for creating it, though it is a pre-req. csi-driver is like any other tool, so if you can export NFS share with others then its ok you can use it.
I would like to setup the CSI driver to use NFS volumes on NAS shares on the Unity.  Currently I don't have iSCSI ports on our array. Is this a requirement? From below it seems to be that to use NFS iSCSI ports are a requirement ? Requirements
What physical ports on unity are needed to use NFS with Unity CSI driver ?
