NEM 24P 10GE module connection to Ops Center

If I have Ops Center on a blade EC/Proxy controllers, and I need to know that if I wanted to define a network which will require a physical fabric, do I have to have a vNIC configured per vlan on the controllers or will NEM 24P 10GE vlans be enough, I mean will Ops Center controllers deal with those networks just being configured on NEM or do the controllers need to have an IPed NIC on each VLAN that is present on the NEM.
