|“At some point in the future, I think we’re likely to see most of the power and cabling overhead with the raised floor used mainly for water piping to serve cooling needs of close-coupled cooling systems.” — Robert McFarlane|
Today’s WhatIs.com Word of the Day is raised floor, a data center construction model in which a slightly higher floor is constructed above the building’s original concrete slab floor, leaving the open space created between the two for wiring or cooling infrastructure.
Although raised floors have been the norm in the modern-day data center, we have recently begun to see a return to construction that puts power and cooling above the hardware instead of below it. It’s being pushed as being a “green data center” solution. For one thing, putting the cooling system in the ceiling and allowing physics to let the cold air fall uses less power.
