How It Works
Three steps to persistent, high-speed storage for all your AI workloads.
Create a Volume
Create a persistent volume from the dashboard or CLI. Choose NVMe SSD or HDD and set your size.
Attach to Any Instance
Mount your volume on any GPU instance. Near-zero latency over InfiniBand internal network.
Data Persists Forever
Terminate your GPU instance — your data stays. Launch a new GPU and re-mount instantly.
Manage Storage from Anywhere
Use the dashboard, CLI, or REST API — whatever fits your workflow.
# Create a 500GB NVMe volume
wollnut storage create --size 500gb --name my-data --type nvme
