Which is an example of a rack-oriented cooling architecture?

Question

Options

• AA cooling unit is located in the ceiling plenum to cool the data center racks.
• BA cooling unit is located within the rack itself to cool the contents of that rack.
• CA cooling unit utilizes perforated raised floor tiles to deliver cool air to the rack.
• DA cooling unit is located along the perimeter wall of the data center to cool a specific zone of racks.

• B

• C

• D

Explanation

Option B is correct because rack-oriented cooling means the cooling mechanism is integrated directly into or attached to the rack itself, targeting only the heat generated by components within that specific rack - this is the defining characteristic of a rack-level cooling architecture.

Option A describes a room-level or facility-level approach, where overhead ceiling plenums distribute cool air broadly across the data center rather than to a specific rack. Option C describes a raised-floor cooling strategy, which is also a room-level method that delivers conditioned air through perforated tiles to the general area beneath and around racks. Option D describes a zone-level or perimeter cooling approach (similar to traditional CRAC units), which serves a group of racks in a region rather than a single rack.

Memory tip: Think of the word "rack-oriented" as meaning the cooling unit is married to the rack - it lives in it, moves with it, and serves only it. If the cooling unit serves anything larger than a single rack (a row, a zone, a room), it is not rack-oriented.
