OSN storage can be requested through the ACCESS (formally XSEDE) User Portal. Allocations of a minimum 10 terabytes and max of 50 terabytes supporting up to 1.6 million files can be requested through the ACCESS allocation service (an overview is available here). The best way to get started is to request an ACCESS Explore allocation. Larger allocations can be accommodated with additional review. If your project needs more than more than 50 terabytes or more than 1.6 million files, please contact us directly to discuss before you submit your request.
Please contact us if you have any questions or need assistance with submitting these requests, OR if you do not have an account on the ACCESS portal. We will be happy to help you!
An active research dataset can remain in OSN storage up to five years.
