(3) VF NIC
With LPAR manager, you can enable SR-IOV function of physical NICs and set a
network segment for VF NIC to a physical LAN controller in shared mode. Defining
connection between the network segment and VF NIC allows communication with
external networks. Network segments can be set on the
assignment screen.
Communication is available between VF NICs connected to the same network
segment without using external network. VF NICs connected to different network
segments require an external network for communication.
Up to two physical LAN controllers can be assigned to LPAR manager.
The following table describes relation between the number of Shared NICs and
network segment identifiers.
