This is a list of storage options on CLA's Linux systems.
Home Directory
Each Linux user account receives a home directory (aka home folder). Your home directory is available in the Linux environment and is also accessible by desktop computers via SMB or SFTP.
- Path: /home/<Internet ID>
- Backup: 30 days
- Limit: 250GB
- Cost: None
Hint: use the terminal command du -sh . (including the period) when on lts or SSHed to a node to check your storage usage
Labs, Research Projects, and Classes
You may request a dedicated folder (aka share) for use by a group (e.g. research lab) or your project. This space is available in the Linux environment and is also accessible by desktop computers via SMB or SFTP. This storage is hosted on OIT's Research Data Storage system.
- Path: /labs or /pkg
- Backup: 30 days
- Limit: variable
- Cost: OIT plans to implement an annual cost for usage over 5TB per PI or research group starting in 2023 or 2024.
- Please contact us at [email protected] to request storage
Local Scratch Space
/scratch.local is highly ephemeral and the files are only available to the node on which the storage is mounted. It should be used when staging content for immediate use by a process running on the node.
- Path: /scratch.local
- Backup: None, deleted when job is finished
- Limit: 1TB but shared between all users on a node
- Cost: None
Please see our page on how to use Local Scratch Space for more information.
Network Scratch Space
/scratch.network is ephemeral in the sense that it is not backed up and files > 30 days from its creation date are subject to deletion on a FIFO (first in, first out) basis when the storage becomes full. While files exist for a longer time, and are available on any of our integrated compute nodes, as I/O is over the network, it is significantly slower.
- Path: /scratch.network
- Backup: None
- Limit: 1TB
- Cost: None
