① SA Source

Context Before

Recall from above that a Vera Rubin NVL72 cluster built with Q3400-X800 switches at 1.6T logical ports per GPU cannot scale beyond the maximum cluster size of 93,312 GPUs. Even if future switch generations continue to double the maximum possible switching capacity per switch box, the per GPU bandwidth is also expected to double, which means that the effective logical port count in a cluster network is unlikely to change.

Evidence

What this means is that deployment of large-scale GPU clusters will continue to require multi-plane network architectures.

Context After

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.

② Atomic Claim

這表示大型 GPU cluster 的部署未來仍會需要 multi-plane network architecture。
