QuettaFlow VasRack

80 to 126kW in one cabinet is roughly three to five times what a well-built air-cooled rack manages, and it is the number that decides whether a given room can host a cluster at all. Floor space stops being the constraint and power delivery becomes it.

pPUE below 1.1 means under 10 percent of the energy going into the room is spent on cooling rather than compute. Over a multi-year training programme that is a line on the operating budget, not a rounding error, and it is the argument that usually justifies immersion over a chilled water retrofit.

It takes the same Lead Wealth modular servers as the VasEdge and supports NVIDIA L20, RTX 40 and 50 series, A series and H series cards. Deployment runs from a single cabinet to a scalable cluster, so the first rack does not commit the design to a particular final size.

QuettaFlow states an operating range to 45C, which is five degrees wider than the VasEdge and is the specification that matters most for deployment in this region. A cabinet that tolerates a hot plant room does not need the plant room to be conditioned first.
