Nexus GB200 NVL72 Blackwell Rack-Scale Cluster

72 Blackwell GPUs as one giant GPU — exascale-class AI in a single rack.

Overview

The GB200 NVL72 connects 36 Grace CPUs and 72 Blackwell GPUs through fifth-generation NVLink into a single 72-GPU domain inside one liquid-cooled rack. Nexus Compute specifies, sources through authorized channels, integrates, and acceptance-tests the rack, XDR-ready fabric, and storage as one warranty-backed system for organizations planning frontier AI build-outs.
