Connecting GPUs in the Scale-Out InfiniBand Network - Line hint:

Context Before
For the Vera Rubin NVL72 deployment however, there are two 800G OSFP cages per GPU for a total of 1.6T per GPU bandwidth. Having two 800G logical ports per GPU is advantageous because it allows multi-plane network deployments without complex fiber management—by splitting one logical GPU two ways to two different leaf switches.
Evidence
As such, larger network clusters can be built with two 800G logical ports than if only one 1.6T logical port were used.
Context After
The maximum number of hosts that can be supported using a switch of k ports on an L-layer is:
② Atomic Claim
因此，相較只使用 1 個 1.6T logical port，使用 2 個 800G logical ports 可以建立更大的 network clusters。
