Datacenter Knowledge has 2 posts up about Switch Communications new datacenter in Las Vegas, which they are claiming is the highest-density datacenter in the world.
Switch Communications says it is successfully cooling a section of its Las Vegas data center running at nearly 1,500 watts per square foot using air cooling. How are they accomplishing this?
The key to Switch's high-density cooling is a design known as Thermal Separate Compartment in Facility (TSCIF), according to company co-founder Rob Roy. The ingredients in this approach include high-capacity AC units placed outside the data center area, and a tightly integrated hot aisle containment system for the racks. Here's an overview:
* The cabinets are set on a slab, with no raised floor.
* Chilled air is delivered into the cold aisle near the ceiling rather than through the floor, and enters the cabinets through the front.
* Each cabinet fits into a slot in the TSCIF unit, which encapsulates the rear and sides of each cabinet, while the open front extends beyond the enclosure.
* The hot aisle containment system delivers waste heat back into the ceiling plenum, where it can be returned to the chiller.
