      LUSTRE* SOLUTIONS
    • PARALLEL FILE SYSTEM

Data-intensive workflows in Research, Government, Energy and Earth Sciences are driving analytics and modeling to extreme levels of fidelity in areas like materials modeling, ignition, brain mapping, climate studies, forecasting and more.

Exponential growth in data inputs is required to fuel every significant step taken to close the gap between a model and the physical world. This data growth profile puts storage infrastructure squarely in the critical path – driving requirements for extreme, dependable performance that scales.

Developed to overcome the toughest storage and data management challenges in extreme, data-intensive environments, DDN EXAScaler appliances scale up and/or out, leveraging a SSD-accelerated, hyper-converged, parallel architecture to deliver industry-leading performance and efficiency for HPC Big Data workflows.

EXTREME PERFORMANCE AND SCALE, NEW TECHNOLOGIES AND OPEN SOURCE

Researchers are the most demanding user community in HPC. To boost research productivity, advanced high performance sites are moving to centralized storage models. A centralized storage approach allows them to provide data access speeds to feed more concurrent projects at higher data rates, incorporate best-of-breed open source and new technology wherever possible, and improve cost-effectiveness and management overhead. A primary requirement when building centralized storage infrastructure is the power to grow to support site-wide data needs, even over multiple clusters or generations of clusters.

DDN EXAScaler – THE INDUSTRY’S MOST ADVANCED LUSTRE APPLIANCE

DDN builds on the experience of over a decade of Lustre development, system design, implementation and support to deliver the EXAScaler line of Lustre appliances. EXAScaler combines the industry’s most powerful storage architecture with the leading Lustre distribution, DDN integration tools, system monitoring tools and deep bench of Lustre experts across engineering, pre-sales and support. The result is the industry’s fastest, most advanced Lustre appliance, proven in the most demanding environments in HPC.

DDN ENTERPRISE LUSTRE DISTRIBUTION
DDN has been working with the core Lustre development team and delivering Lustre solutions for 15 years. To provide our end users with the best Lustre experience bar none, we build EXAScaler Enterprise Lustre Distribution on top of the supported community branch, hardening it for months through extensive automated testing to enhance stability, uptime, and performance.  EXAScaler comes with a time-proven and tested approach to high availability in Lustre, and with an extensive set of tools that simplify deployment, maintenance, and support.

DDN is a very active member of the Lustre community and has contributed many performance, scalability and management features including development or lead test owner on all major features in the recent Lustre 2.9 release.  DDN contributes all core Lustre enhancements to the community and has never forked Lustre.  Because we can incorporate them in our own release faster, DDN developed features are often available to DDN customers exclusively for a period of time before they are incorporated into the main branch.
