Infrastructure
Every rack, every rail, accounted for.
A look inside the hardware we build: GB300 NVL72 racks and HGX B300 nodes, the rail-optimized fabric that joins them, the storage that feeds them and the operations that keep them busy.
Front
The rack, top to bottom.
Eighteen compute trays and nine NVLink switch trays share one 48U MGX rack with eight power shelves. Everything that carries data faces the cold aisle.
Rear
Power, coolant and NVLink — all blind-mate.
A 50 V busbar down the middle, four copper spine cartridges either side of it, supply and return manifolds at the edges. Trays slide in and connect to all three at once.
One compute tray
Two superchips, cooled at the source.
Each GB300 superchip pairs a Grace CPU with two Blackwell Ultra GPUs over NVLink-C2C. Cold plates sit on every hot component; fans only handle what is left.
02 — Cluster explorer
Walk a cluster before you reserve it.
Every rack, switch and rail of a representative build, in a full-screen explorer. Switch configurations, isolate a rail, hide a layer, or open any rack to see what is inside it and where its links go.
