Have you ever been to one of the Cisco Customer Proof of Concept (CPOC)? If you like fridges you will enjoy it. This is the one located in Sydney.
The video is a bit shaky but you can get the idea – several corridors like this one and if you pay attention you will see two Cisco Nexus 7000 Series and four UCS chassis fully populated. The UCS kits were deployed by me but shame on me I recorded the video with them turned off.
