ceiling height of DC

[princee18]

Is there any ratio which has to be maintained between the size of a DC and its ceiling height. What should be the minimum height of a DC?

I don’t think there is a standard measurement for it; I think you just have to make sure there is enough space between the ceiling and the equipments.

The old rule of thumb for open-air data centers with subfloor cold air -- 9 ft plus 1 ft for every 20W/sq ft in heat density -- becomes difficult to apply beyond 100W/sq ft or so. Higher densities involving more close-coupled cooling reduce the need for overhead (and subfloor) plenums, so ceiling height can be reduced to the needs of equipment plus overhead utilities -- electrical, plumbing, data, fire suppression, lighting.
