ARCC provides two options for research data storage. Alcova, and Pathfinder. As of June 1st, 2024, Alcova will begin migration from Alcova to ARCCs Data Portal

Research Data Storage on Alcova is ARCC’s Data Portal, HPC Storage, and Old Alcova are subject to default quotas as listed on our Pricing Sheet /wiki/spaces/AIP/pages/2062024761.

Data on HPC

ARCC high-performance storage system (HPS) for Beartooth is a high speed, tiered storage system designed to maximize performance while minimizing cost. Beartooth is intended to be used for storing data that is actively being used.

Researchers working with or generating massive data sets that exceed the default 5 TB allocationallocations or quotas, or having tha have significant I/O needs should consider the following options:

  • Rent space on shared hardware: There is a set price per TB per year. Please contact ARCC for the exact price.

  • Purchase additional storage disks to be incorporated into Beartooth: This option is appropriate for groups that need more space than the free offering, but don’t have the extreme space or performance demands that would require investing in dedicated hardware.

  • Buy your own dedicated storage hardware for Research Computing to host: If you need more than about 15 TB of storage or very high performance, dedicated hardware is more economical and appropriate. The exact choices are always evolving. Please contact ARCC for more information.

File Deletion and Purge Policy

This describes ARCC's file deletion policy:

  • /home: Home directories will only be deleted after the owner has been removed from the university system.

  • /project: Project directories will be preserved for up to 6 months after project termination.

  • /gscratch: Files that have not been accessed in 45 days will can be purged, and data . Data may be deleted as necessary.

  • /lscratch: Files will be are automatically removed after thirty (30) days of not being used or accessed14 days.

Costs Associated with HPC Storage

  • Please see Cost of Resources/wiki/spaces/AIP/pages/1627815937

    • If users require quota increases on Beartooth file storage, they may apply for a one-time, no-cost capacity increase by providing written justification for the amount of extra storage and it’s benefit to the UW mission of research, education and economic development.

      • This capacity increase lasts for the life of the storage system (typically 3 years), the increase must be approved by ARCC Leadership, and is subject to a 10TB max limit.

      • In all other cases, the user will be charged per Cost of Resources as listed here /wiki/spaces/AIP/pages/1627815937.

  • Users may request capacity increases on the ARCC Service Portal.
