The company carries products that provide block, parallel file and [[object storage]]. [[Block storage]] devices store data in chunks with a maximum fixed length. Parallel file systems spread the data across more than one storage device to provide redundancy and increase performance. Object file systems separate the file metadata information from the rest of the file data and store them in separate devices. The Lustre and Spectrum Scale file systems are examples of parallel file systems that are supported by some of DDN's storage systems. High speed interconnects such as [[InfiniBand]] are also supported by some of DDN's storage systems.
The company also provides a storage management tool to configure and monitor DDN storage devices as well as a line of [[flash storage]] appliances. For example, DDN's Infinite Memory Engine (IME), a flash-native data cache, allows data to reside next to compute in a shared pool of non-volatile memory (NVM). In 2018, DDN introduced a line of all flash products designed to address AI and analytics workloads in GPU compute environments, known as A3I. <ref> [https://www.enterpriseai.news/2018/10/04/ddn-nvidia-blueprints-unified-ai-appliance-with-dgx-1s/]<
DDN's enterprise business unit supplies solutions for virtualization, with Tintri, software defined unified storage, with Nexenta, and all flash primary unified storage, with IntelliFlash.
