GPU Storage Infrastructure.

Purpose-built for GPU-adjacent storage. PCIe Gen4 fabric routes NVMe capacity directly to GPU-heavy hosts — no CPU bottleneck, no fabric hops.

Ships inside DF-R1
OVERVIEW

Storage placed next to the GPUs that use it.

AI training and inference stall when storage can't keep up. GPU Storage Infrastructure eliminates the storage tax by placing NVMe capacity on a PCIe Gen4 fabric that reaches GPUs directly.

Deploy NVMe capacity behind the same PCIe fabric that connects your GPU accelerators — with GPUDirect-friendly topology and DMA-optimised paths.

ARCHITECTURE

Solution block diagram.

The block diagram shows how GPU Storage Infrastructure stitches a large NVMe pool directly onto the GPU fabric — bypassing CPU-side bottlenecks. GPUs peer with NVMe endpoints across the PCIe Gen4 fabric backplane (Tier-1 US PCIe switch silicon inside) using GPUDirect Storage. Training batches stream from SSD into HBM at bus-native throughput; the CPU is freed from I/O staging. Result: shorter training epochs, higher GPU utilisation, and lower cost-per-token for large-model training runs.

Connection diagram.

The connection diagram maps a typical GPU training row. Two or four GPU nodes each expose a PCIe HBA into the DF-S06 chassis via MCIO cables. The chassis houses the fabric plus a large NVMe pool. Front-end networking (200/400 GbE or IB) stays with the GPU nodes; DF-S06 does not sit in the data-network path. Management runs on a separate 10 GbE port. Use this diagram to plan GPU rack elevation, cable lengths, and PSU sizing when adding NVMe drives.

HOW IT WORKS

Detailed description.

GPU-intensive AI training and inference are I/O-bound as often as they are compute-bound. Between epochs, models re-read datasets. Between requests, inference services fetch features. Every stall costs GPU utilisation.

GPU Storage Infrastructure places NVMe capacity behind the same PCIe fabric that the GPUs sit on. With GPUDirect-compatible topology, storage-to-GPU transfers can bypass CPU memory copies — a direct DMA path from NVMe to HBM.

The Datafabrix Gen4 Fabric Backplane provides the low-hop, deterministic fabric that makes this work. Combined with our reference GPU host designs, you get storage that keeps GPUs fed.

Applications

  • LLM training data plane — Multi-terabyte datasets streamed directly to GPU HBM.
  • Vision model training — Sustain millions of image reads per second per GPU.
  • Inference feature retrieval — Low-latency RAG feature fetches from NVMe to GPU.
  • Checkpoint I/O — Fast periodic checkpointing without CPU-bound bottlenecks.

RACK-LEVEL ARCHITECTURE

Where DF-S06 sits in your rack.

PCIe Gen4 backplane wired directly between GPU accelerators and NVMe storage — line-rate GPU-to-flash. The solution slots into a standard 19-inch rack alongside your existing servers, storage, and network fabric — no re-architecture required.

Target deployments: GPU compute where I/O to storage is the training-loop bottleneck.

  • Cabling: standard PCIe host adapter → PCIe cable → DF-S06 chassis
  • Power: standard C13/C14 rack PDU, 1+1 redundant PSU option
  • Management: 10 GbE + IPMI/BMC out-of-band + Datafabrix DCIM integration
  • Cooling: fits standard rack thermal envelope, no liquid cooling required
01

Install in rack

Slide the DF-S06 chassis into a standard 19-inch rack slot. Rail kit included. Cable to your PDU and management network.

02

Connect PCIe host

Install the Datafabrix PCIe host adapter in your existing server. Connect via PCIe cable to the DF-S06 backplane uplink.

03
