Context Before
Source: SemiAnalysis AI Networking Model ↗
We think the second cluster with two switch planes will likely be the more prevalent reference architecture for Vera Rubin NVL72 InfiniBand deployments.
Evidence
As pointed out earlier, what is unique about both switches is that each switch box consists of four 28.8T Quantum-3 Switch ASICs for a total of 115.2T per box switching capacity
Context After

② Atomic Claim
兩種 switches 的特點是，每個 switch box 都由 4 顆 28.8T Quantum-3 Switch ASICs 組成，總 switching capacity 為每 box 115.2T。
