Context Before
What this means is that deployment of large-scale GPU clusters will continue to require multi-plane network architectures. Do note however that multi-plane networking architectures are not limited by size and we have also seen NVIDIA reference architecture deployments with multi-plane clusters that are significantly below 100k GPUs each.
In multi-plane network architectures using the SN6600 switch instead of the CPO switch, each GPU fans out to multiple switch boxes using fiber shuffles. This requires customers to deploy shuffle boxes, patch panels and unwieldy octopus cables outside the switch box that introduce complexity in installation and maintenance.
Evidence
Some of Nvidia’s CPO SKUs – such as the SN6800 and Q3450 –contain such a fiber shuffle within the switch box, with each optical engine fanning out to different logical ports

② Atomic Claim
部分 Nvidia CPO SKUs（例如 SN6800 與 Q3450）把這類 fiber shuffle 整合在 switch box 內，每個 optical engine 向不同 logical ports fan out。
