I was looking at QLE8142 product overview at figure 1-2 "Combined SAN and LAN Function on One Converged Network Adapter" on page 1-3 "QLogic Converged Network Adapter", where this image can be found:

Do you think those bandwidths are fixed, 4Gb FC and 1GbE per port, or they are distributed depending on load?
 
Hi,

as the docu says the IO rate is 10Gb. This normally means you can use both ports with full-duplex mode.
PCIe 2.0 is capable of 2GB/s.
Also, here they meant 2000MBps per port, full duplex so yes you can.
 
I don't know. Yeah, the IO rate is 10Gb, but the fact that they put in the picture 1GbE and 4Gb FCoE, threw me off.
I went for dual card instead, HP NC522SFP NIC, dual 10 GbE guaranteed, and Dell-QLE2562 HBA, dual 8Gb FCoE (instead of 4).

Always better.

I tried such a combi card a few years back and needed also FCoE drivers to get it to work. It was a pain and it was not stable. We threw them out and also went with dedicated cards - no problems since.
