Fornax User Resource Allotments and Costs

V.1.3 July 17, 2026

Upon your first login to the Fornax Science Console you will have:

• 1000 credits for spending on cloud resources (compute, storage, and egress); this is renewed yearly, at the beginning of the fiscal year (Oct. 1). If you need more credits before the renewal date, contact the Fornax Helpdesk.

• A 200 GB ceiling to the private storage available in your Home Directory; if your work requires more, please see the options below or contact the Fornax Helpdesk.

• Access to additional, private S3 storage, mounted as “s3-storage” under your Home Directory, for a cheaper storage option (see table, below)

• Additional /scratch storage space that can be expanded to temporarily house very large datasets for software that expects data mounted as a traditional file system. See Data Storage in the Fornax docs for more details

The Fornax Science Console Dashboard will help you keep track of what you have spent.

For more information, see: Compute and Storage in the Fornax docs
