DDN

DDN (DataDirect Networks) is the world’s largest privately held storage company. It builds AI-enabled data infrastructure that powers 75 % of the world’s top 200 AI supercomputers, including systems for OpenAI, NVIDIA, and major cloud providers.
Main introduction
DDN transforms raw data into business value through a vertically-integrated stack: high-performance NVMe flash arrays, parallel file systems, policy-driven software, and cloud-native management. The platform is engineered for the extreme concurrency, low-latency and petabyte-scale throughput demanded by modern GPU clusters, autonomous driving, life-science analytics and large-language-model training.

Key features
• AI200, AI400, AI500X and AI7990 appliances deliver up to 1.4 TB/s read bandwidth and 80 M IOPS in a single rack, verified by MLPerf benchmarks.
• EXAScaler parallel file system provides POSIX, NFS, SMB and S3 gateways from the same namespace, eliminating data copies and reducing GPU idle time.
• Hot-node technology tiers data automatically between NVMe, disk and cloud object stores while keeping metadata on flash for consistent sub-millisecond latency.
• Cloud-native control plane (DDN Insight) offers GUI, CLI and REST APIs for one-click deployment, predictive analytics, proactive health checks and charge-back reports across on-prem, hybrid and multi-cloud footprints.
• Enterprise-grade security: FIPS-140-2 encryption, role-based access, WORM immutability, ransomware detection snapshots and synchronous replication to remote sites.
• Green design: 2.5× better power efficiency vs. competitive arrays, liquid-cooling ready, and 5:1 data reduction guaranteed.
• Global support: 24×7 follow-the-sun coverage, 98 % first-call resolution, and optional AI-certified professional services to accelerate time-to-insight from months to days.
