Cisco SFP+Cu Twinax (10GB) vs LC Fiber?

We are making a connection from our Dell servers to our Nexus 5010 switch using 10GB Twinax for a FCoE setup.

We may have to use 10GB LC Fiber instead.

My question is, does the medium matter when transfering 10 gigs of data? or will their be gotches from our standard 10GB copper configuration? I thought FCoE required the twinax. If we use LC Fiber will we need specific drivers on our CNA cards?

Thanks

Ok Don however we have specific setup like in the zoning on the nexus that enables FCoE specifically. That is one of the gotchas I'm talking about. Could I simply remove the lines that are for FCoE when using Fiber?

I'm not following you.  If you remove the connections that are carrying your FCoE traffic, then you're going to lose your FCoE connection.
Exactly, I'm talking about replacing them with LC to LC Fiber connections. Different protocols
What changes would need to be made in this case. We already have lines on the FCoE zoning that enable FCoE and all that.

Twinax vs. fiber is physical layer function.

Whatever configuration that you use on your fiber ports would be the same commands that you would use on the twinax ports.
