Context Before

Evidence

The bidirectional SerDes technology employed on the copper backplane is used for NVIDIA’s scale-up network.

Context After

For Vera Rubin NVL72, the scale-up network continues to be rail-optimized with all-to-all connectivity between each GPU and switch ASIC in the scale-up domain.

② Atomic Claim

Copper backplane 上採用的 bidirectional SerDes technology，用於 NVIDIA 的 scale-up network。
