My servers have built on-board QDR IB via QSFP :)

And I didn't want/mean to start any interconnect wars. I know how those end up 
going. If you have 10G infrastructure then 10G is the way to go (to some size 
anyway before the 10G switches become either way oversubscribed, or off the 
chart expensive)

Well, the servers we are buying now have dual on-board 10GigE SFP+
ports which seem to add almost nothing to their cost.

But OK, you caught me.  The real reason I want 10GigE is because that
is the infrastructure I already have.  :-)
