Storage

Denvr Cloud provides two primary storage categories.

• Direct Attached Storage (DAS)

• Network Attached Storage (NAS)

Direct Attached

Low latency ephemeral storage, ideal for caching training datasets, model checkpoints and intermediate results. Denvr hosts include up to 30TB with read throughput up to 30 GB/s. On Denvr virtual machines these disks can be formatted and mounted with the following:

sudo mkfs -t ext4 /dev/vdc
mkdir -p /home/ubuntu/direct-attached
mount /dev/vdc /home/ubuntu/direct-attached

Tips

• Cache your models and datasets here to avoid bottlenecks during training or inference tasks.

• Backup results or checkpoints to our NAS for reuse on other Denvr hosts.

Network Attached

Reliable distributed network storage for managing VM root disks, saving model checkpoints, and sharing datasets across hosts and even teams. Our network storage comes in general and high-performance tiers.

General Storage

Low cost, encrypted and redundant storage for home directories, system files, reference datasets or docker images. Petabyte-scale with read throughput up to 1GB/s.

Tip

• Ideal for virtual machine root disks (/dev/vda) and custom images.

High-Performance Storage

High performance, encrypted and redundant storage for sharing large model checkpoints and datasets across a cluster of machines or between users. Petabyte-scale with read throughput between 5 and 10GB/s depending on region.

Tip

• Backup DAS cached model checkpoints or training results here for future analysis or retraining.

• Personal shares are user specific stores that can be accessed from our virtual machine or application services. Default location is ~/personal.

• Tenant shared can be accessed by any user in an account and is also available from either virtual machines or applications. Default location is ~/tenant-shared.
