File systems

The Denvr Cloud is pre-integrated with network-attached file storage systems to preserve data sets, model checkpoints, and system output.

High Performance Storage


  • Petabyte-scale network-attached Flash SSD with configurable data protection

  • Up to 5 GB/s read throughput

  • Encrypted at rest and delivered to GPUs over tenant-private networking

Primary use:

  • Working space for very large datasets that are copied in and out for local Cache

  • Application file systems, databases, and large capacity/high IOPS requirements

  • Faster version of User Storage but is typically used for pre-processing and streaming large datasets in and out of Cache

User Storage


  • Petabyte-scale RAID-protected storage, optimized for low cost, parallel I/O, and persistent storage

  • Encrypted at rest and delivered to GPUs over tenant-private networking

  • Up to 1 GB/s of read throughput

Primary use:

  • Used for home directory files, application code and configuration, and datasets

  • Clients may optionally prefer to keep data in their own on-prem storage systems and leverage Denvr for caching

  • GPUs can process data directly from User Storage, but may benefit from Cache storage depending on your use

Cache Storage


  • Up to 16 TB of direct-attached NVMe SSD per bare metal node

  • Lowest latency and up to 12 GB/s read throughput

  • Cache is non-persistent and is freed when applications are stopped

Primary uses:

  • Volumes provide local storage for model training data, checkpoint files, and intermediate results data

  • Data loaders should copy training data into the Cache Storage to ensure full GPU utilization and not bottleneck performance on slower network-attached storage
