The problem with 10G is that there are at least 3 copper and 2 fibre
standards to chose from, so chosing 10GB-t may not be right.  Most systems
have SFP pluggable modules so you can chose the type you use.
While fibre is currently common, I think that's mostly because it's used
for inter-rack/site mostly; but you don't need it for the machines in a rack.

There is an elwctrical standard for connction prior to the phy, I think
that's xaui, I'm not sure if that's the same as the SFPconnections.
