Context Before

Evidence

VR NVL72 CPX (Dual Rack): Rubin CPX deployed in a separate rack alongside the VR NVL72 rack

Context After

The standalone/dedicated rack direction materially changes the deployment calculus. A dual-rack approach allows hyperscalers to scale prefill and decode capacity independently, optimize datacenter power envelopes, and reduce system-level failure domains versus tightly coupled trays. More importantly, it formalizes architectural disaggregation between inference prefill (compute-bound) and decode (bandwidth-bound).

② Atomic Claim

VR NVL72 CPX Dual Rack configuration 則把 Rubin CPX 部署在獨立 rack，與 VR NVL72 rack 並列。
