Large Scale Storage (LSS) is a cost-effective and scalable storage solution available to all University of Iowa faculty, staff, departments and researchers.  

LSS is useful for:

  • backups
  • archives
  • storing large files (e.g. videos and images)
  • HPC workloads that demand high bandwidth and storage

LSS is approved for the following data classification levels:

  • Public
  • Internal
  • Restricted *
  • HIPAA * (SMB/CIFS only)
  • Export-Controlled (Please contact research-computing@uiowa.edu before putting Export-Controlled data on LSS)

* If you intend to store protected health information (PHI) from UIHC on LSS, you are responsible for obtaining approval from the UIHC Data Governance group.  Please contact icts-bmi-consulting@healthcare.uiowa.edu for more information.

Storage space can be rented on a monthly basis (“shared storage”, the most common LSS usage) or for a fee ITS - Research Services can maintain & support storage nodes purchased by you (“dedicated storage”).

If you are interested in dedicated storage, please contact research-computing@uiowa.edu before purchasing storage nodes as some conditions and considerations apply.

Benefits of LSS

  • 1TB-100TB+ shared space
  • Optimized for HPC workloads that demand high bandwidth and storage
  • Daily backups and snapshots help recover a deleted file (or a different version of a file) as far back as 30 days, unless other increments are needed
  • Replication copies files to a remote site for disaster recovery (optional)
  • Access from off campus is available through VPN (UI Anywhere) or Virtual Desktop

LSS does not support complex nested permissions inside a single file share.

No cost storage for faculty

For faculty, a single 5TB share with backups is available upon request at no cost on either LSS or the Research Data Storage Service. Additional space may be purchased at the standard rate.
