Connecting GPUs in the Scale-Out InfiniBand Network - Line hint:

Context Before
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 port achieves only a maximum cluster size of 93,312 GPUs:
Evidence
(2\left(\frac{\frac{115{,}200}{1{,}600}}{2}\right)^3 = 2\left(\frac{72}{2}\right)^3 = 93,312)
Context After
By one 1.6T logical port, we mean that the two 800G OSFP cages connected to each GPU are connected to a single, dual-port 1.6T transceiver at the leaf layer because the two 800G ports are effectively performing the function of one 1.6T port—and hence the term “logical”.
② Atomic Claim
上述 93,312 GPUs 的計算式為：(2\left(\frac{\frac{115{,}200}{1{,}600}}{2}\right)^3 = 2\left(\frac{72}{2}\right)^3 = 93,312)。
