What is CAC Archival Storage?

  • CAC Archival Storage provides low-cost, high-performance option for storing research data.
  • CAC Archival Storage has a direct 100 Gbps connection to Internet2.
  • CAC Archival Storage is not mountable by running jobs, instead the user must transfer their data from the CAC Archival Storage to an accessible server using Globus.
  • Data in CAC Archival Storage is intended to be an additional copy of user data; CAC Archival Storage is not backed up or snapshotted.
  • All CAC resources are suitable for unregulated, non-confidential data (reference for details).
  • Globus users have easy access to add, delete, and share their data using any Globus endpoints.
  • Some of the Globus endpoints available include:
    • CAC user home directories (cac#home)
    • XSEDE sites:
      • Stampede (xsede#stampede)
      • Lonestar (xsede#lonestar4)
      • TACC Archival Storage (xsede#ranch).

First Step - Enable (or create) CAC project for Archival Storage and add users where appropriate

  • To use the CAC Archival Storage service, you must be a user of a CAC project where Archival Storage is enabled.
  • The project PI can add users and verify that Archival Storage is enabled at the Manage CAC project page.
  • Don't have a project? How to start a CAC project?.
