Context Before
The standalone/dedicated rack direction materially changes the deployment calculus.
Evidence
A dual-rack approach allows hyperscalers to scale prefill
Context After
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
Dual-rack approach 讓 hyperscalers 可以獨立擴展 prefill……
