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.

Evidence

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.

Context After

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

在使用 SN6600 switch、而非 CPO switch 的 multi-plane network architecture 中，每顆 GPU 會透過 fiber shuffles fan out 到多個 switch boxes。
