① SA Source

• Source: 開啟完整 SA 文章
• Section: CPX Form Factor
• Line hint: 143

Context Before

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

Evidence

The standalone/dedicated rack direction materially changes the deployment calculus.

Context After

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

轉向 standalone／dedicated rack 會實質改變 deployment calculus。
