Cisco came out with their UCS servers about five years ago, this included both B and C series x86 servers. The B series being blades and the C series being rackmounts. In just five years, Cisco UCS blades have become the #1 blades sold in the US and #2 world wide. In those years Cisco has been the only company that has shown growth in this server market (a whopping 39%).
As a Cisco Champion and an engineer who specializes in Cisco UCS, this is a proud day for me. It's amazing to provide customers with a product that I really believe in...and clearly others believe in it as well. For more information on this check out this deck provided by Cisco.
