Supermicro begins shipping Vera Rubin NVL72 racks to customers

NVIDIA/Vera Rubin

Supermicro said it has started shipping NVIDIA's Vera Rubin NVL72 racks, moving NVIDIA's next AI platform from demonstrations into customer deployments. Each rack works as one large computer: 72 Rubin GPUs and 36 Vera CPUs linked by NVLink switches, delivered with Supermicro's liquid-cooling and power infrastructure. Supermicro did not disclose volumes, prices, customers or delivery dates.

• Per rack: 20.7 TB of HBM4 memory on the GPUs plus up to 54 TB of LPDDR5X, in 18 compute trays and nine sixth-generation NVLink switch trays.
• Supermicro's reference building block links 16 racks: 1,152 Rubin GPUs and 331 TB of HBM4 within a 5 MW power envelope.
• Cooling is direct liquid cooling (Supermicro's DLC-2): cold plates on the chips, coolant distribution units and rear-door heat exchangers.
• This is a vendor shipping update; it does not confirm broad availability or a specific customer's deployment.
