File and Data Storage: AFS

Effective Monday, Nov. 23, 2020, new faculty and staff members are no longer auto-provisioned with AFS user volumes, but can submit a Help request if personal AFS user volume is needed. New students and post-docs will continue to be auto-provisioned. 

This change does not impact existing AFS directories or the process for adding permissions for new individuals to those existing directories. Your existing space and everything in it remains intact. 

Please see this IT Community news item for more information.


AFS (Andrew File System) is a distributed, networked file system that enables efficient file sharing between clients and servers. AFS files are accessible via the Web or through file transfer programs such as OpenAFS or Fetch (Macintosh) and SecureFX (Windows).

Currently all users with a full-service SUNet ID are granted 5 GB of AFS file space. Additional disk space is available by request for faculty-sponsored research including dissertations.

New faculty and staff members are not auto-provisioned with AFS user volumes, but can submit a Help request if personal AFS user volume is needed.
