A Crash Course in CRAC Cooling
February 25th, 2011 By: Rich Miller
What’s a CRAC? It’s shorthand for Computer Room Air Conditioner, a key component in data center cooling. In this video, SoftLayer “Social Media Ninja” Kevin Hazard gives a basic explanation of how data center CRAC units work, along with a walk-around demonstration of airflow within a hot aisle/cold aisle raised-floor environment. Due to the ambient noise in the data center, Kevin’s explanation had to be “yelled.” This video runs about 2 minutes.

This was a good very basic primer on DC cooling. But there is so much more going on behind the scenes I would like to see.

force of habit to critique the air distribution architecture in that room but it is not set up to handle high density cooling without task, close-coupled, supplemental cooling. It’s also not very efficient at effectively segregating hot/cold air mixing as there is no dropped ceiling to be used as a hot air return plenum, and no form of hot aisle containment.

liked this –as a very good primer on DC cooling.
Agreed that there is lot to criticize but this serves as a good primer.
I restrained my self from critique.
