Cisco are at least proving the accusation
That Cisco UCS is simply a ploy to trap customers into the "Cisco Powered...." money pit for a bit longer. Cutting off Dell now that they have found a few customers who actually bought the sales pitch and paid the injurous Cisco markup for commodity servers is not surprising. Cisco can't exist in a commoditised market, they have too much overhead and now that everyone can do scale out Ethernet (oh, sorry, Cisco can't) for big virtualisation platforms, Infiniband etc in horizontal scale out for HPC (sorry Cisco, port density, cost...) and there is a glut of the other device types out there Cisco have to join the IBM / HP game of locking you into a single vendor data centre to carry on milking you.
Don't worry, the bankers will carry on paying taxpayer's money to Cisco and keep them alive...
