Business Challenge story

To enable real-time understanding of natural language, Nuance must rapidly and cost-effectively ingest, store and analyze huge volumes of speech data.


Nuance uses IBM® Spectrum Scale™ to give its HPC community fast, massively parallel access to billions of files, with automatic policy-based storage tiering that balances storage cost and performance.


Software-defined storage with policy-based file management optimizes performance while limiting costs. Tiering gives 20 percent performance boost. Non-disruptive scalability keeps HPC grids productive.
