Oak Storage

Oak is a High Performance Computing (HPC) storage system available to research groups and projects at Stanford. Learn more about Oak or contact us at for further questions.

Oak Service Overview

Oak is available for use by all Stanford University and affiliated research projects and groups. This includes healthcare researchers, as well as researchers from the SLAC National Accelerator Laboratory (SLAC). Please note that a four year commitment from the PI is required when purchasing Oak.

Service Description

For more details about Oak, please look at the official Oak Service Description available here (Stanford only).

Two flavors of the service are available for purchase with a 4-year commitment:

Service flavor Service description Service price
Filespace PIs/Faculty rent disk space in increments of 10 TB and 1.5 million inodes1. $42.95 per 10TB / month
or $50 per TB / year
JBOD PIs/Faculty purchase one or more full disk arrays (JBODs), with 550 TB usable capacity each, that is/are supported and administered by the SRCC team as part of the overall Oak service. A JBOD comes with a maximum of 82.5 million inodes**. JBOD cost2 + $687 per JBOD / month
(service only)

Oak storage is readily available from both the Sherlock and XStream HPC clusters, but also from multi-protocol gateways (Globus, SFTP, NFSv4, Samba/CIFS…). Restrictions may apply and personalized gateway service will incur additional costs to the PI.


Oak is NOT HIPAA compliant and is not a storage choice for any data that include PHI or PII. The system is approved for storing Low and Moderate Risk data only and is not suitable for data classified as high-risk. For more information about data risk classifications, see the Information Security Risk Classification page

Oak group space

  • There are only group/project spaces on Oak (similar to how /home/groups or /scratch/groups work on Sherlock).
  • When a group directory is created on Oak, we use the PI/faculty SUNet ID as the group name (eg. /oak/stanford/groups/SUNetID/).
  • Or, alternatively, a project directory can be created under /oak/stanford/projects/.
  • File system group quotas are used to limit the amount of file system space group/project can use.
  • Each group is provided with a personal dashboard that provides information about available disk space (quota) and usage.

Managing users

  • The PI provides an initial list of SUNet IDs having access to the new group or project shared directory on Oak.
  • The PI gets access to a Stanford Workgroup to manage authorized users (please be aware that changes made in Workgroup Manager may take up to 4 hours to be propagated to Oak).
  • Members of the workgroup can then organize files as they desire in the group/project directory (POSIX ACLs are supported).

  1. JBOD pricing is dependent upon hard disk market variations (contact us for current pricing

  2. inodes are filesystem objects like files and directories
