Context Before

Evidence

While not part of the Rubin NVL72 rack, Spectrum-6 CPO enables even larger scale-out clusters with its doubled radix

Context After

Rubin Oberon Rack: NVL72 not NVL144 nor NVL36

Since the announcement of GB200 at Nvidia GTC 2024, the concept of an AI server system has shifted from a chassis to a rack scale system. In our GB200 article , we discussed the evolution of Nvidia AI server form factor from HGX (8 GPU per node) to Oberon (NVL72 rack scale). While the HGX form factor still exists, the majority of Nvidia’s Blackwell GPUs are integrated in the Oberon form factor. Rubin will also be offered in both HGX and Oberon systems.

② Atomic Claim

雖然不屬於 Rubin NVL72 rack,Spectrum-6 CPO 透過加倍 radix,可支援更大型的 scale-out cluster。
