When combined with NX-OS based platforms+VMware as a solution, it is a no-brainer why UCS has gotten the market traction that it has. Less cabling, addressing limitations and restrictions of legacy technology like STP (admittedly Fabric Path is propreitory but it works wonders on Nexus), redundancy offered by OTV (again propreitory but works!), vPC+ , cut-down on power requirements with virtualization and consolidation...the list goes on.

Customer acceptance are the last word on the vailidity and effectiveness of any technology hitting the market and in this case it is easy to see why the customers have embraced UCS as readily as they have.

What is impressive is the amount of obvious effort that has gone into implementing the entire solution from a technical perspective, whether propreitory or not.

To reiterate, Well Done!
