Organizations have unprecedented access to insights about their data with AI, Analytics, and High Performance Computing (HPC). Increasingly data-intensive workflows place storage infrastructure firmly on the front line of performance requirements, driving the need for scalable, dependable performance both on premise and in the cloud.


DDN has developed new data management and integrity filesystem features exclusive to its appliances and cloud offerings in Exascaler. A powerful data orchestration engine, stratagem provides policy-based placement controls that allow users to maintain control over the contents of data.

  • Hot Nodes accelerate data access, auto-caching data on the local NVMe, avoiding networking round trips, and keeping infrastructure freed up to serve other workloads.
  • Hot Pools ensures efficient use of storage by strategically moving data between high-performance flash and high capacity disk.

With EXAScaler, you can manage, create, and analyze far more data than ever before, reducing time-to-insight with industry-leading performance.
