Latest News

  • Currently /ifs is read only, and /zfs must be used for active work
  • You have received an email indicating the data you have access to on /zfs
  • All new projects are being created on /zfs
  • Offsite backups on /zfs are currently active
  • We are currently tuning performance on /zfs

If you have any questions or concerns, please email for clarification.

Where’s the data?

  • All automatically migrated directories below will be hidden until the switchover is complete on December 2, 2021.
  • All data in /ifs/projects will be moved to /zfs/projects/faculty

  • All data in /ifs/gsb will be handled on a case-by-case basis
  • Links to shared datasets stored in /zfs/data will be provided on an as-needed basis

What are we doing?

  • Retiring the current Isilon storage system (mounted at /ifs on the Yens)
  • Installing a new storage system, designed by the Stanford Research Computing Center
  • Copying data to the new system
  • Making a read-only copy of the old system available for 12 months
  • Organizing the new system to clarify data administration

Why are we doing it?

  • The Isilon system is reaching the end of its planned lifespan
  • The new system will have larger capacity at less cost
  • The new system will be easier to administer for users and technical staff

What do you need to do now?

  • Plan to update your code to refer to paths in /zfs instead of /ifs
