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, archiving, and storing large files (e.g. video or image files).  

LSS is also optimized for HPC workloads that demand high bandwidth and storage and is especially appropriate for researchers working with large data sets in need of additional backups.

LSS does not support complex nested permissions inside a single file share. Support for this service is available Monday-Friday during normal working hours. 

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 recover (optional)
  • Access from off campus is available through VPN (UI Anywhere) or Virtual Desktop


Shared storage (standard LSS usage)

Space is $35 per terabyte/year (billed monthly at $2.92/TB) per copy of data.

For researchers with a faculty appointment, 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.

Note for UI3 Cluster Faculty: After December 31, 2020, UI3 Cluster Faculty will be charged for their LSS shares as per https://informatics.uiowa.edu/ui3-transition-faq.

Dedicated storage nodes

Dedicated storage nodes incur an up-front cost of $2500 per node to secure 5 years of maintenance & support from ITS-Research Services staff.

Nodes which are more than 5 years old may continue to be used at a cost of $2500 per year under some conditions.
