My pal Randall, of Vizworld.com fame, sent me a pointer to a YouTube video from a presentation filmed at the Silicon Valley Leadership Group’s Data Center Energy Efficiency Summit.
In the video the presenter walks us through a cold aisle containment experiment Pixar did when adding very dense compute racks to a room already maxed out on cooling load. They used total containment: panels and curtains in the room, blanking panels on the racks, and air dam foam under the floor.
Pixar saved $30,000 over conventional cooling, on an $18,700 implementation cost, for a return on investment of 3.7 months (including PG&E rebates). And the figures are indepently audited. At just over 3 minutes, definitely worth a watch.
