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
Aside from the X800-Q3400 air-cooled switch, NVIDIA will also offer a CPO version, which is the X800-Q3450 containing the same 144 ports of 800G

② Atomic Claim
除了 air-cooled X800-Q3400 switch，NVIDIA 也會提供 CPO 版本 X800-Q3450，同樣具備 144 個 800G ports。
