That's exactly my point if you've been following this thread.  Internal IT *can* build/buy their own private cloud.  The VCE vBlock is one example of that, and there is a good reason why the vBlock has <GASP> fabric extenders.  Applying the same old thinking to data center design isn't going to build a private cloud.

Agree 1000%.  This thread started off in the minutia of server access layer switches, but there is a much larger equation here as you point out (the multitude of servers).  However while the switch itself may seem like minutia, the architectural plays you make at the server access switching layer can have a broader reaching impact on power & cooling efficiencies.  Again there is a reason the VCE vBlock has <GASP> FCoE.

What difference would that make? We're all adults here.
