### Compute

The ML4AI lab has the following compute VMs:

TODO:

- Add information about venti

### Storage

The lab has a 20 TB NFS share mounted at /media/mule on the kraken, leviathan, and orca VMs.

There is a 90 TB NFS share mounted at /media/snail-ssd on the orca VM.

TODO:

- Add information about timelord

TODO:

- Add information about other legacy SISTA systems that are still operational.

### Backup

- VMs running on InfoSci servers (e.g., eel, starfish) are backed up every 6 hours
- As of 2025-03-06, VMs running on lab servers (e.g., kraken, leviathan) are not backed up, but the plan is to include them in the backup system in the future.
