Data Center Containment 101

A Subzero White Paper by Gordon Johnson

New White Paper discusses the Essentials of Data Center Containment

Regardless of if we’re entering a data center for the first time or have been doing so for
years, most data centers have something in common. As you walk through rows of racks,
you’ll alternate between cold and hot aisles. You’ll hear expressions like “CRACs”, “PUE”,
“White Space”, “Cold Aisle Containment”, “Hot Aisle Containment”, and many more. The
purpose of this White Paper is to assist those new to the data center and those assigned
with making key decisions to get the most out of existing “legacy” and newly designed data

Since energy efficiency and data reliability are key goals for anyone managing or associated
with data centers, how can we achieve both in the shortest amount of time while getting
the quickest ROI (Return of Investment)? When is it more appropriate to use one type of
containment instead of another type? Which saves more money? This paper will answer
these and other questions.
