Reference Architecture for RAG on H200 GPU Servers
A RAG stack is a retrieval, storage, inference, and governance system, not just a vector database attached to a model. The practical design uses H200-class GPU servers for generation, CPU/storage tiers for indexing, measured retrieval quality, and RDP GPU Mart support to map each tier to India-ready procurement.

TL;DR
- Keep ingestion, embedding, vector search, reranking, and generation as separately observable stages.
- Size storage and network paths for corpus growth, not only the first demo index.
- Use prompt logging and DPDP-aware retention controls before exposing sensitive enterprise content.
What should buyers verify before sizing?
The first pass should identify workload shape, concurrency, governance obligations, and site readiness. FOMALHAUT treats these as engineering inputs, not sales decorations. This article uses NVIDIA H200 Tensor Core GPU, NVIDIA NeMo Retriever documentation, NIST AI Risk Management Framework 1.0, MeitY DPDP Act material, MLPerf Inference Datacenter as the evidence base, then maps the implications to RDP GPU Mart categories where the fit is clear.
| Layer | Primary decision | Failure mode to test |
|---|---|---|
| Ingestion | Batch cadence and document parsing | Stale or duplicated chunks |
| Embedding | Model and dimensionality | High recall with weak precision |
| Retrieval | Vector + lexical blend | Citations that do not support the answer |
| Generation | GPU memory and batching | Latency spikes under concurrent users |
Which technical assumptions matter most?
- NVIDIA H200 platform material in 2024 lists 141 GB HBM3e memory.
- NIST AI RMF 1.0 was released in 2023 as a risk-management frame for AI systems.
- DPDP Act, 2023 adds governance requirements for personal data used in enterprise AI workflows.
The quoted source for this article is NIST AI Risk Management Framework 1.0: "NIST frames trustworthy AI around validity, reliability, safety, security, accountability, transparency, explainability, privacy, and fairness." The quote is used as positioning context only; capacity and procurement still need workload validation.
How does this map to RDP GPU Mart?
RDP GPU Mart should be used as a Make-in-India, INR-transparent route to shortlist the relevant DRACO / GPU servers + Storage configuration, validate rack and support assumptions, and keep procurement traceable. It should not be read as a reseller claim for third-party vendors named in the research log.

What are the practical next steps?
1. Collect model, dataset, retention, concurrency, and latency targets. 2. Run a small benchmark or proof-of-concept before locking a bill of materials. 3. Compare workstation, server, and storage options against power, cooling, support, and DPDP constraints. 4. Route any content or UI changes through review; this article changes only KB content.
FAQ
Is this article a final bill of materials?
No. It is a sizing and architecture guide. A final bill of materials needs workload measurements, site constraints, support expectations, and commercial validation.
Does RDP GPU Mart resell every vendor named here?
No. Vendor names are used for comparison and technical context. RDP GPU Mart positions Make-in-India GPU infrastructure options where they fit the buyer problem.
Should teams optimize for GPU count first?
No. Optimize for workload behavior, memory, concurrency, latency, data governance, and site readiness. GPU count follows those decisions.
Why include India-specific constraints?
Indian buyers often need INR/GST procurement clarity, GeM readiness, support paths, DPDP-aware handling, and power/cooling checks. These constraints can change the right architecture.
