A variety of storage systems with varying characteristics make up the data platform available to the ITS-RC community. As datasets increase in size, complexity, and/or sensitivity, more attention is required to ensure best match of resources to the tasks at hand.


  • High capacity storage
  • OK to compute against, however as IO increases, /work becomes the better option
  • OK to hold inactive data sets like a near-line archive
  • If you have 30TB or more of truly inactive data, we can assist in moving it to Cloud based cold archive, achiving greater data durability and lower storage costs

Your directory primary storage is: /users/{o}/{n}/{onyen}
This storage is provided by the same hardware as /proj

  • High capacity storage
  • OK to compute against, however as IO increases, consider copy/move to /work for processing
  • OK to hold inactive data sets like a near-line archive
  • If a meaningful amount of cold data accrues, it can be packaged and MOVED to cloud archive, providing more working space for your warm data
  • /users is not intended to be used for team oriented shared storage, like /proj; it is intended to be your personal storage location; think of it as a capacity expansion to your home directory. Note that /work is NOT intended to be a personal storage location; /work is for data actively being processed, especially for workloads with high IO requirements.
  • 10 TB quota


  • High performance storage
  • New as of 2022
  • Intended for active data only, aka hot data, actively being processed
  • /work is NOT intended for holding inactive data
  • Please MOVE inactive data to your /users directory

  • High capacity
  • Read-only at this time
  • In process of migrating out of /ms
  • All data in /ms must be re-homed

Cloud based cold data archive

  • The most durable, least expensive storage option available, presuming there is low probability of needing to retrieve/access frequently or at large data volumes

The following two systems are built upon old hardware that is no longer on maintenance, and thus at non-trivial risk of loss as compared to the storage systems listed above. This is the prior generation of /proj hardware; high capacity, decent performance.


Useful for:

  • Data that can be re-acquired
  • Intermediate results of analysis and workflows
  • Staging area to re-organize data on its way somewhere else, such as Cloud based cold archive
  • etc.


  • Read only
  • Suggestions for data sets to add are welcome
  • Disposable data; if systems fail, data can be re-acquired

Examples of data sets in /datacommons:

  • 1,000 Genomes
  • Berkeley DeepDrive, bdd100k
  • SCAMPS Dataset, Camera Measurement of Physiology
  • Indoor Scene Recognition
  • Stanford Dogs
