What this means for the fabric
8 compute NICs means 8 rails. In a rail-optimized design each of those rails is sized on its own against the node count, then multiplied back up, so the leaf tier is driven by the rail count and not by the total endpoint count.
Storage and in-band management are separate fabrics with their own switches and their own optics, and the 1 BMC port per node feed the out-of-band network, which also has to carry every switch and every PDU in the cluster.
Power and racks
At 8 kW typical draw, this node fills a rack's power budget long before it fills the space. A 45 kW rack takes 5 of them on power alone, against 7 on rack units. Power is what actually sets the rack count.
Notes
Verified: 6RU 8-GPU HGX platform, ~8,750 W peak with 8x H100, redundant 2800 W supplies. Also ships in H200, B200, and MI300X variants.
