Figure 1-23 Definition of Network Segment ID on LPAR manager
In the figure above, an external network is used to establish communication
between shared NIC #0 of LPAR1 set to segment 1a and shared NIC #1 of
LPAR2 set to segment 1b or shared NIC #2 of LPAR2 set to segment 2a.
Note:
• Total throughput of shared NICs is 3 Gbps per LPAR manager.
Tip:
• For communication between shared NICs set to a same network segment,
an external network is not used.
However, for communication between shared NICs to different network
segments, an external network is used.
VF NIC
A network segment of VF NIC can be set when SR-IOV as a hardware
function of physical NIC is available on LPAR manager, and NIC scheduling
mode is shared mode.
NIC assigned the network segments is called "VF NIC".
VF NIC is set on the "Virtual NIC Assignment" screen.
For LPAR manager, up to 8 physical LAN controllers can be assigned and up
to 16 physical ports can be assigned.
The following tables show a combination of logical port numbers, a detection
number of LAN controller and network segments for each hardware
configuration as examples.
