What is Locker

Locker is a cost-optimized, high-capacity, large-file storage service for research data. Locker provides high-performance for large files, and allows investigators across U-M Ann Arbor to connect their data to computing resources necessary for their research, including U-M’s HPC clusters.

Locker can only be used for research data. It is designed for data that does not require frequent access, for example, data that is at the end of its useful life-cycle. It is tuned for large files (1MB or greater), and large numbers of small files should not be stored on the service without being aggregated in some fashion (as through tar). Locker can be used in combination with the Globus data management sharing system for hosting and sharing data with external collaborators and institutes.


  • Locker is available to researchers from any academic unit.
  • Locker space can be purchased with a minimum of 10TB with 1TB increments thereafter
  • Locker uses the Globus File Transfer Service
  • Locker does not yet provide the option of secure storage for regulated and/or sensitive data, but it is scheduled on the roadmap.
