NVIDIA GB300 NVL72 72-GPU Rack (Pegatron)
NVIDIA GB300 NVL72 rack-scale GPU system — 72 Blackwell Ultra GPUs and 36 Grace CPUs in a single, fully-integrated, liquid-cooled Pegatron NVL72 rack.
NVIDIA GB300 NVL72 rack-scale GPU platform, delivered as a single factory-integrated Pegatron NVL72 rack. Seventy-two GB300 Grace Blackwell Ultra GPUs connect over fifth-generation NVLink into one coherent accelerator — roughly 20.7 TB of HBM3e per rack for the largest AI training and inference workloads, liquid-cooled through a facility coolant distribution unit (CDU) sized to the site. Factory-integrated and NVLink-domain-complete. Configuration and availability confirmed at quote.
