This video of a LEGO Data Center is clearly a detailed homage to a real data center, built and filmed by YouTube user "eduardotanaka." He used 5,772 pieces, 28 Minifigures, 1 Light Brick, 1 meter of fiber optic strand and spent 8 hours building this unique creation. You can build your own too, using his model and instructions that were uploaded to the Lego LDD gallery at the LEGO web site (search for data center). He notes that he has plans for future expansion: Facilities and security management with temperature, sound, IR and door sensors as well as automatic locks powered by LEGO NXT are on the drawing board. We think he's probably going to install real, yet tiny, working IT equipment in the future! This video runs 4 minutes.
