Multi-node clusters support two types of shared storage: persistent disks that survive beyond cluster lifecycles, and ephemeral shared storage that exists only during the cluster’s lifetime.

​
Storage Options

​
Persistent Storage

  • Persists after cluster termination
  • Shareable across multiple clusters
  • Requires pre-created disk with Active status
  • Use case: Long-term data, models, and datasets

​
Ephemeral Shared Storage

  • Temporary storage for cluster lifecycle only
  • Automatic creation during cluster provisioning
  • Shared between all nodes in the cluster
  • Use case: Temporary files, intermediate processing data

​
Step-by-Step Guide

1

Go to `Multi-Node Cluster` and select a provider. For persistent storage, ensure the provider and location match your existing disk. Look for the `Add Shared Filesystem` button.

To use existing persistent storage, click `Add Shared Filesystem` and select your disk.

Provision with disk
This disk will remain available after cluster termination and can be reattached to new clusters.
3

For temporary shared storage, simply enter the desired size in GB. This creates a new shared filesystem that's accessible by all nodes but will be deleted when the cluster terminates.

Shared disk for cluster
Ephemeral storage is deleted when the cluster terminates. Do not store critical data here without backups.
