So I now have one on order that should sort it out but will keep you posted.

Good point about the uplink port but I have not found anything that would suggest a proprietary protocol. The module in the switch is a U691D SFP+ one.

Many thanks again.
I think you have gotten some things mixed-up.

The Dell switch supports stacking uplink, 10GB-CX4, 10GBase-T and 10GB-SPF+ modules. So there are options which are available.

As for the Intel card, there are several options. Intel has CX4, 10GBase-T and SPF+ server adapters. (I have several dual-port CX4 adapters).

So, you can easily mix these units to fit your needs.
