Disaggregated pre-fill and decode pod orchestrators decouple compute-heavy prompt encoding from memory-bound autoregressive decoding in enterprise vLLM clusters. Unified serving pods cause long prompts to hijack Tensor Cores, spiking time-to-first-token and inducing severe jitter across concurrent streaming users. Our architecture isolates pre-fill onto dense H100 pods, streaming chunked KV-cache pages over 400 Gbps RoCE v2 direct to high-concurrency L40S decode ranks. This achieves sub-four-millisecond time-to-first-token, expands decode batch sizes by five point four times, and cuts cloud inference TCO by fifty-four percent.
