In the fast-evolving world of artificial intelligence, AI infrastructure solutions must deliver more than just raw power – they need to provide unmatched performance, efficiency, and scalability to keep pace with today’s most demanding AI workloads. DDN, a global leader in AI storage solutions, has once again raised the bar with its next-generation AI400X3 storage appliance. Powered by DDN’s EXAScaler® parallel file system, the AI400X3 achieved standout results in the MLPerf® Storage v2.0 benchmarks, setting a new standard for storage for AI that combines exceptional performance density with a compact, energy-efficient design.
Why AI Storage Matters for Scalable AI Deployments
As organizations across industries – from healthcare to finance to autonomous systems – scale their AI initiatives, the need for robust AI storage becomes critical. Modern AI workloads, such as large language model (LLM) training and computer vision, demand high-throughput, low-latency data access to keep GPUs fully utilized. Without a high-performance AI storage solution, even the most advanced GPUs can become bottlenecked, slowing down model training and increasing operational costs.
DDN’s AI400X3 addresses these challenges head-on. Designed to power the AI infrastructure of the future, this compact 2U appliance delivers relentless performance while minimizing datacenter footprint, power consumption, and cooling requirements. Whether you’re a startup exploring AI storage solution reviews or an enterprise building global infrastructure for AI, the AI400X3 offers a proven, scalable solution to accelerate your time-to-insight.
Efficiency Meets Performance: A Sustainable Approach to AI Storage
In today’s datacenters, space, power, and cooling are critical constraints. The AI400X3’s compact 2U form factor and low power consumption make it a standout choice for organizations prioritizing sustainability without sacrificing performance.

MLPerf Storage v2.0: Proving DDN’s Leadership in AI Storage
The MLPerf Storage benchmark is the industry’s gold standard for evaluating storage for AI workloads. It tests a storage system’s ability to handle the intense data demands of AI training, simulating real-world scenarios from single-node setups to large-scale, distributed environments. DDN’s AI400X3 excelled in both categories, showcasing its versatility and power.
Single-Node Performance: Powering AI with Minimal Footprint
For organizations just starting their AI journey, the AI400X3 delivers exceptional performance in a compact package. In single-node MLPerf testing, the AI400X3 achieved:
- Highest Performance Density: Supported 52 simulated H100 GPUs on Cosmoflow and 208 H100 GPUs on ResNet50, all from a single 2U, 2400-watt appliance.
- Blazing-Fast IO: Delivered 30.6 GB/s read and 15.3 GB/s write performance, enabling lightning-fast checkpointing for Llama3-8b models (3.4 seconds to load, 7.7 seconds to save).
These results highlight why DDN is a top choice among AI storage companies. The AI400X3 makes it easy to unlock powerful AI infrastructure performance without requiring extensive hardware investments, making it ideal for teams looking to scale efficiently.
Multi-Node Performance: Scaling AI Without Limits
For enterprises training large-scale models, the AI400X3’s multi-node performance is a game-changer. Key highlights from the MLPerf Storage 2025 benchmarks include:
- Massive Throughput: Sustained 120+ GB/s read throughput for Unet3D H100 training.
- Unmatched Scalability: Supported up to 640 simulated H100 GPUs on ResNet50 and 135 on Cosmoflow – a 2x improvement over last year’s results.
These metrics demonstrate the AI400X3’s ability to handle the most demanding AI infrastructure solutions, ensuring consistent, high-throughput data delivery under massive GPU loads. By keeping GPUs saturated with data, the AI400X3 accelerates training cycles, improves model resilience through frequent checkpointing, and reduces total infrastructure costs.
