For those of you that like to look at other people’s datacenters, here are some more images of CERN’s computer center. Beautiful stuff, and you can clearly see the different stages in the construction, from building the racks to the installation of the servers.
If you want to see more about the way these data centers are constructed, have a look at this video from Switch. It’s essentially a big commercial for their new SuperNAP facility, but it covers the major aspects of data center design. If that’s not enough for you, this page has many other interesting videos.
