Inference Storage Planning for a Thousand-GPU AI Datacenter

Direct answer

The core of thousand-GPU datacenter storage planning is a three-tier architecture plus KV tiering: the measured one-FX100-per-8-nodes ratio, a fully reproducible Python TCO model, and gated joint tests to control build risk.

The storage design of the thousand-GPU plan

Mingxin's thousand-GPU plan (128 nodes × 8 × MI308X) includes a fully reproducible TCO model: Clos network BOM, three-tier storage (local / all-flash pool / capacity tier) with KV tiering, power and PUE, depreciation modeled line by line, and a 10,000-run Monte Carlo sensitivity analysis (dc1k_plan).

The storage ratio anchor comes from measurement, not guesswork: a single 100 GbE port sustains 8-node KV read-back (R2/R3 bandwidth data), so FX arrays deploy at 1:8; network and component anchor prices all cite public sources.

Gated construction: stop-loss if gates are missed

G1 delivery acceptance (materials inspected, array self-test with 24/24 drives recognized) → G2 single-node baseline (R1 basis reproduced ±10%) → G3 main joint-test gate (TTFT reduction ≥25%, throughput inside the measured +29–40% band, 8-node shared read-back approaching the NIC ceiling) → G4 stability (72-hour stress + fault injection transparent). Each gate stops the project if missed — customers do not pay for unverified promises.

The complete costing model is reproducible Python after NDA — a datacenter is a heavy-asset decision, so we make verifiability part of the plan itself.

FAQ

Can an already-built datacenter be retrofitted?

Yes: KV tiering is an incremental architecture that leaves compute and network mostly untouched. Start with a single-array pilot (the ten-week G1–G4 process) and scale after verification.

Can we run the TCO model ourselves?

Yes: Python source is provided after NDA — change parameters and recompute every conclusion, including parameter sets unfavorable to Mingxin. That is part of the verifiable commitment.

What share of investment should storage take?

The joint-test basis is within ~10% of GPU investment; the exact share depends on the workload profile (inference share, context length, switch frequency). The calculator produces a range first.
