FCoE through LACP/VPC on server with two dual-port CNA

Dear Community,


Would you please share the best practices to connect blade server via B22 FEX with two dual-port CNA? B22 is single-homed to each of two Nexus 5k, hence, we use VPC for Ethernet traffic of blades because each chassis is linked by two separate single-homed B22.


Does it make sense to aggregate all four interfaces on server into one LACP/VPC port-channel and bind two corresponding VFC interfaces on 5k switches (one per each fabric) to the port-channel interface on Nexus? Seems it doesn`t and it`s more optimal to have LACP/VPC for Ethernet traffic only and keep two separate interfaces on server intended exclusively for FCoE (bind VFC to the physical interfaces) but I`d like also to rely on your experience in similar cases.

 

Thanks in advance,


Best Regards

Re: FCoE through LACP/VPC on server with two dual-port CNA

Hello Balaji,

 

Thank you for sharing VPC design.

However, my question concerns mainly how to configure switch side for the server with two dual-port CNA adapters. Do you have any best practices or any working solutions there?

 

In general, my question is similar to what was discussing in https://community.cisco.com/t5/server-networking/fcoe-through-lacp-or-vpc/td-p/1658510

 

But the only answer in that thread doesn`t fully cover all possible best practices  and their limitations

 

Thanks,

Best regards
