Liquid-assisted air (in-cabinet coil)
Air moved across a water-cooled coil inside the cabinet rather than cold plates on the package. The dominant architecture of the Cray XT, XE, XK and XC generations, and the step between room air and direct-to-chip liquid.
Why this part
The Cray XT and XE answer: keep the air path but shorten it, moving air vertically through the cabinet across a water coil rather than around a room. Jaguar, Titan, Blue Waters, Cori, Trinity and Piz Daint all used it. It is the intermediate step that let a decade of machines grow denser without asking sites to plumb water to every board, and it is the reason so many facilities built in that era could later be upgraded rather than replaced.

“Units recorded” sums only the edges where a public source states a quantity. It is a floor, not a total, and should never be read as installed base.
