AIStor Fuels the AI Factory

NVIDIA STX defines how enterprise AI factories store, move, and access data at modern AI speeds. AIStor is the unified data foundation accelerating training, enterprise RAG, and real-time agentic inference throughout the AI lifecycle.

High-Throughput AI Training

AIStor saturates GPU interconnects during training by delivering data at the speed GPUs consume it, eliminating the storage bottleneck that limits cluster utilization.

GPUDirect RDMA for direct GPU-to-storage transfers

Parallel data loading across distributed training jobs

Eliminates CPU and network bottlenecks in the data path

Enterprise RAG at Scale

AIStor stores and serves the knowledge that enterprise RAG pipelines depend on — with the performance and reliability production AI demands.

Millions of vectors and documents at sub-millisecond access

Native S3 compatibility for seamless pipeline integration

Scales with retrieval demand without reconfiguration

Supercharging Inference for AI Factories: KV Cache Offload as a Memory-Hierarchy Problem

How AIStor + NVIDIA Works

AIStor deploys within the NVIDIA STX reference architecture as the unified storage layer, replacing fragmented multi-tier architectures with a single high-performance data store that feeds every stage of the AI pipeline.

AIStor Inside NVIDIA BlueField-4

AIStor runs natively on the NVIDIA BlueField®-4 DPU, putting storage compute directly on the SmartNIC and eliminating host CPU overhead entirely.

Storage processing offloaded to BlueField-4 ARM cores

Host CPU freed entirely from storage I/O

AIStor operates at wire speed on 800GbE fabric

Purpose-built for AI factory scale deployments

Storage at Wire Speed

AIStor integrates with NVIDIA GPUDirect® RDMA for S3-Compatible Storage to enable direct memory transfers between storage and GPU, bypassing the CPU and system memory entirely.

GPUDirect RDMA for S3-Compatible Storage is available now as a tech preview.

Data moves from AIStor directly into GPU memory

Eliminates CPU bottlenecks in the training data path

Enables storage to keep pace with 800GbE GPU interconnects

Validated on NVIDIA BlueField-4 SmartNIC infrastructure

KV Cache Offload: Inference Memory Hierarchy

AIStor acts as a high-speed memory tier for KV cache during inference — extending effective GPU memory capacity without sacrificing latency.

Offloads KV cache to fast object storage under memory pressure

Sub-200μs retrieval latency preserves inference SLAs

Enables long-context and multi-agent inference at scale

Transparent to the inference stack via standard S3 APIs

Architected for NVIDIA STX

MinIO’s minimal footprint integrates natively with the NVIDIA BlueField-4 DPU that underpins the STX architecture.

Static binary under 200 MB

No external metadata databases or background services

Runs natively within BlueField-4 DPUs, eliminating dedicated x86 storage nodes

Proven Results

Performance validated across real AI factory workloads—training, inference, and retrieval at scale.

12× GPU Throughput

AIStor with GPUDirect RDMA delivers 12× the GPU throughput of a standalone NVMe configuration — saturating the interconnect so GPUs are never waiting on data.

5× Training Data Per GPU Hour

Enterprises using AIStor in AI factory configurations process 5× more training data per GPU hour compared to traditional storage approaches.

106M Vectors in 120 Seconds

AIStor ingests and indexes 106 million embedding vectors in 120 seconds — enabling enterprise RAG pipelines to operate at a scale that matches production data volumes.
