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

Evidence

we have also seen NVIDIA reference architecture deployments with multi-plane clusters that are significantly below 100k GPUs each.

Context After

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.

② Atomic Claim

SemiAnalysis 也觀察到 NVIDIA reference architecture 採用 multi-plane clusters，而每個 cluster 的規模明顯低於 10 萬顆 GPU。
