Just want to verify communication between UCS servers on same chassis but having active vNICs on different FIs (Diagram attached). I suppose all commuication between server-A & server-B will happen through Layer 2 switch as server-A will generate an ARP request for Server-B, that will be passed over to FI-A and then to L2 switch down to FI-B, where server-B will respond back with it's MAC that will then be passed to Server-A via FI-B to L2 switch to FI-A.I don't expect any traffic between servers A & B be routed via firewall? Is there anything I need to be careful about in this design? Going forward we will have multiple subinterfaces on the firewall for different VLANs and all servers will use Firewall as default gateway.

Hi Muhammad,
Your understading is correct, as long as the traffic is in the same vlan the upstream layer-2 switch should be able to take care of it.

you may want to look at the throughput of your firewall for server-server traffic in different VLANs. If your L2 switch is 10G but your firewall is only 1G then you could have a potential bottle neck.
