Context Before
Source: SemiAnalysis AI Networking Model ↗
We think the second cluster with two switch planes will likely be the more prevalent reference architecture for Vera Rubin NVL72 InfiniBand deployments.
Evidence
When used in conjunction with the VR NVL72 servers, the signal from the NIC at the leaf layer is split four ways – 200G each way – to each switch ASIC within the box

② Atomic Claim
搭配 VR NVL72 servers 時，leaf layer NIC 的 signal 會分成四路，每路 200G，分別進入 box 內各顆 switch ASIC。
