The Depot Object Store offers research groups in need of centralized object storage unique features and benefits:

  • Available

    To any Purdue research group as a purchase in increments of 1 TB at a competitive annual price or you may request a 100 GB trial space free of charge. Participation in the Community Cluster program is not required.

  • Accessible
    • Access to the Depot Object Store is via S3-compatible APIs. Applications requiring POSIX filesystem access should continue to use the Data Depot Filesystem.
  • Capable

    The Depot Object Store facilitates joint work on shared files across your research group, avoiding the need for numerous copies of datasets across individuals' home or scratch directories. It is an ideal place to store group datasets, models, or raw data.


  • Controllable Access

    Access management is under your direct control. Unix groups can be created for your group and staff can assist you in setting appropriate permissions to allow exactly the access you want and prevent any you do not. Easily manage who has access through a simple web application — the same application used to manage access to Community Cluster queues.

  • Data Retention

    All data kept in the Depot Object Store remains owned by the research group's lead faculty. When researchers or students leave your group, any files left in their home directories may become difficult to recover. Files kept in the Depot Object Store remain with the research group, unaffected by turnover, and could head off potentially difficult disputes.

  • Never Purged

    Depot Object is never subject to purging.

  • Reliable

    Depot Object is redundant and protected against hardware failures by Ceph replication and erasure coding.

  • Restricted Data

    Depot object is suitable for non-HIPAA human subjects data. See the Data Depot FAQ for a data security statement for your IRB documentation. The Data Depot is not approved for regulated data, including HIPAA, ePHI, FISMA, or ITAR data.
