Evidence
To scale beyond the maximum cluster size of 93,312 GPUs, a 2-plane network can be deployed in which each of the two 800G OSFP cages supporting a GPU are linked to separate leaf switches on different network plans. This allows you to build a 186,624-GPU cluster size as diagrammed below and even scale up to 746,496-GPU cluster sizes.

② Atomic Claim
在原文所述假設情境中，要超過 93,312 顆 GPU 的 maximum cluster size，可以部署 2-plane network：每顆 GPU 的兩個 800G OSFP cages 分別連到不同 network planes 上的 leaf switches。
