Turbo
Turbo Research Storage is a high-capacity, fast, reliable, and secure data storage service that allows investigators across U-M Ann Arbor to connect their data to the computing resources necessary for their research, including U-M’s Great Lakes HPC cluster. Turbo supports storage of sensitive data and ARC’s Armis2 cluster.
Turbo can only be used for research data. It is tuned for large files (1MB or greater), but is capable of handling small files such as documents and spreadsheets. Turbo, in combination with Globus sharing, works well for sharing and hosting data for external collaborators and institutes.
The Turbo service is available in a replicated and unreplicated form. Snapshots are available on a daily basis for up to a week. Weekly snapshots are stored for one more week before being deleted. More information for Turbo is available on the Turbo page.

To Order Service
To order Turbo, go to the ITS Service Request System (SRS). Select for NFS volumes (including Multiprotocol to be shared to Linux only or both Windows and Linux) or CIFS volumes (to be shared with Windows only). If you have any questions, contact us at arc-support@umich.edu.
Locker Large-File Storage
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 NFS volumes (but not CIFS) can be used in combination with the Globus data management sharing system for hosting and sharing data with external collaborators and institutes.
The service is available in a replicated and unreplicated form. Snapshots are available on a daily basis for up to a week. Weekly snapshots are stored for one more week before being deleted. More information for Locker is available on the Locker page.

Data Den
Data Den is a service for preserving electronic data generated from research activities. It is a low-cost, highly-durable storage system, and is the largest storage system operated by ARC.
Data Den is a disk-caching, tape-backed archive optimized for data that is not regularly accessed for extended periods of time (from weeks to years). Data Den does not replace active storage services like Turbo and Locker. It is best suited for research data that is not accessed regularly and frequently. Data Den is best accessed through the Globus data management sharing system to move data into and out of tape.
Data Den is only available in a replicated format.

- Amount of storage needed (in 1TB increments)
- MCommunity Group name (group members will receive service-related notifications, and can request service changes)
- Numeric group ID of the group that will have access to files at the top level directory
- Numeric user ID of person who will administer the top level directory and grant access to other users
