Storage Resources

ITaP maintains several different storage resources to accompany computational systems. Here is a brief introduction to research storage resources. More information and detailed documentation are available for each resource listed below.

  • Data Depot

    Research Data Depot

    The Data Depot is a new service from ITaP Research Computing (RCAC) that provides a high-capacity, fast, reliable and secure data storage system designed, configured and operated for the needs of Purdue researchers and campus units in any field and shareable with both on-campus and off-campus collaborators.

    ITaP currently plans to have the Data Depot online for limited trial use by August 29 and available for general use on October 31. As with the community clusters, researchers and campus units will be able to easily purchase capacity in the Data Depot through the Data Depot Purchase page on this site.

  • Group Storage

    Persistent Group Storage

    ITaP Research Computing now offers shared research group storage available from all research clusters or directly usable from labs at a competitive price.

    To purchase access to Group Storage today, go to the Group Storage Access Purchase page. Please contact us via email at if you have any questions.

  • Scratch Space

    Scratch Space

    For Scratch Space, each cluster is assigned a default Lustre parallel filesystem. The Lustre filesystems provide work-area storage optimized for a wide variety of job types, and are designed to perform well with data-itensive computations, while scaling well to large numbers of simultaneous connections.

  • Home Directory

    Home Directory

    Your Home Directory for all ITaP research resources is provided by an EMC Isilon filesystem.

    /home is the primary space used to permanently hold files for a given user. This space has a quota which can be adjusted with the BoilerBackpack Quota Management tool.

    All Home Directory spaces currently reside on 3 PB of redundant, high-availability disk space and is a central component of ITaP's research systems infrastructure.

  • Fortress

    Fortress Archive

    The Fortress system is a large, long-term, multi-tiered file caching and storage system utilizing both online disk and robotic tape drives. ITaP upgraded Fortress from DXUL to HPSS in October of 2011.
