NFS shared storage is an optional filesystem shared across all nodes in your cluster — useful for datasets, checkpoints, and anything you want available on every node.

​
Why use it

A node’s boot disk can be lost if the node is rebooted or relocated due to a hardware fault. Keep important data — datasets and checkpoints — on NFS instead.
Keep anything you can’t afford to lose on NFS. When a node is replaced after a hardware fault, your VM comes back on new hardware with an empty boot disk. Whatever lived only on the old node, including a training run in progress, is gone and can’t be recovered. Write datasets, checkpoints, and results to NFS from the start so a node replacement costs you a restart, not your work.

​
Capacity

NFS shared storage is optional. Let us know if you need it when you request your cluster, and we’ll size it to your workload.

​
Mounting

NFS is mounted at /data on every node by default. You can re-mount or symlink it elsewhere as you like.
When your contract expires, both the boot disk and NFS are deleted immediately. There is no grace period and no recovery. Back up anything important before the expiry date — see Data retention and expiry.
