Remember yesterday when I mentioned the swank HP/EDS datacenter in the UK that’s being atypically cooled? Good, because more information about it is coming to light.
The fresh air will be introduced into the plenum by 7-foot high low-velocity fans designed to maintain a consistent air pressure across the entire room/plenum. Slotted vents in the ceiling allow the fresh air to enter the cold aisles of the data center, which are fully-enclosed by a cold-aisle containment system.
The result is more consistent, energy efficient cooling. Go HP!
