$SMCI is now shipping $NVDA Vera Rubin NVL72 racks, integrated with its Data Center Building Block Solutions and the DLC-2 direct liquid cooling stack.
Per rack:
1. 72 $NVDA Rubin GPUs and 36 Vera CPUs, operating as one machine
2. 18 1U compute trays, each with 4 Rubin GPUs and 2 Vera CPUs
3. 9 sixth generation NVLink switch trays, 216 TB/s of scale-up bandwidth
4. 20.7 TB of HBM4, up to 54 TB of LPDDR5X

Cooling is what Supermicro is really selling, and it comes from its own portfolio:
1. Cold plates, manifolds, hose kits
2. In-row CDUs rated 1.8 MW each, N+1 redundancy
3. Rear door heat exchangers for residual heat
4. Facility-side cooling towers
Every rack is tested with the full stack before it leaves.
"We have spent years building the liquid-cooling stack, the manufacturing capacity, and the deployment teams for exactly this moment," said Charles Liang, president and CEO, Supermicro.
Supermicro also said on its own X account that the first systems went to SpaceX AI, built at the expanded San Jose facility.
Shipping first is the win.
The open question for $SMCI is the margin these racks carry, because this is a company that has taken thin ones before to hold volume.
