Storage

Storage With Backups

Primary storage - excellent for important data that has to be backed up. 

• • • • • • NetApp - 165 TB dedicated to research computing

            • • Network Volumes -   I:\\Research  (Windows),   smb://share.research.pdx.edu   (Mac)

              • NFS volumes:   /vol/share ,   /home ,   /vol/apps  to computational systems

          • Off-site backups - daily **

          • Snapshots - hourly, daily, weekly, quarterly, yearly **

• • • • • • • For more on snapshots, refer to here.

Storage WITHOUT Backups

Scratch volume - temporary storage location for computational work

• • • • • • Coeus HPC cluster and standalone linux compute (agamede, hecate, and circe) -  /scratch   (170 TB)

          • No backups.  No quota. First in, First out deletion rules.

Using Scratch Storage

Creating (allocating) a workspace 

To create a workspace, run the command ws_allocate <ws-name> <days>, where <ws-name> is the workspace name, and <days> is the number of days before the workspace will expire. You can give the workspace any name you like (workspace directories are automatically prefixed with your username, so the workspace name does not have to be globally unique). Running ws_allocate --help will show available options for workspace creation. The maximum number of days before a workspace expires is 30. Allocating using a ws_allocate -m <mail> -r <reminder_days> <ws-name> <days> will send you an email to the <mail> address <reminder_days> before the expiry.

Once the workspace is created, it can be accessed at /scratch/<username>-<workspace-name>.

Listing workspaces

You can list all your active workspaces by running ws_list.

Extending a workspace

If your workspace is about to expire, and you want to keep it around for longer, you can extend the workspace, by running ws_extend <ws-name> <days>. A workspace may be extended a maximum of five times.

Sharing a workspace

You can give access to your workspace to other users using the ws_share command. To give access to a user with username <user>, run ws_share share <ws-name> <user>. You can later revoke access with ws_share unshare <ws-name> <user>.

Network Data Storage and Research Shares

• • • RC offers research or storage shares to PSU faculty and researchers.  Up to 2 TB of storage is free for each researcher/research group.  More than 2TB is available a charge.

    • The default share size is 500GB. Additional storage up to 2TB can be granted upon request, however storage requests over 500GB must be reviewed.

    • A new share can be requested by completing the I Drive Request Form.

    • There are other storage options available to PSU students, faculty, staff.
