Context Before

For Rubin Ultra NVL144 Kyber, there will be no CPO used for scale up, despite rumors from other analysts suggesting scale-up CPO introduction for Kyber. However, optics for NVLink are coming and will be progressively phased in. Scale-up CPO will first be used for the Rubin Ultra NVL576 system to connect between 8 Oberon form factor racks, forming a two-layer all-to-all network.

Evidence

A copper backplane will still be used for scale-up networking within the racks however.

Context After

This is still for low volume / testing purposes.

② Atomic Claim

不過 rack 內的 scale-up networking 仍會使用 copper backplane。
