Evidence
Having two 800G logical ports per GPU is advantageous because it allows multi-plane network deployments without complex fiber management – by splitting one logical GPU two ways to two different leaf switches
Context After
2(k2)L
Illustratively, consider two hypothetical VR NVL deployments with 1.6T and 800G logical ports respectively. A 1-plane, 3-layer network with one 1.6T logical ports achieves only a maximum cluster size of 93,312 GPUs, or:
② Atomic Claim
每顆 GPU 有兩個 800G logical ports 的優點，是可以把一顆 logical GPU 分兩路連至兩個不同 leaf switches，實現 multi-plane network deployments，且不需複雜 fiber management。
