Hi Anna, We’re about to deploy Lustre/HSM with Phobos for a new large research data archival system at Stanford (200PB).
https://github.com/phobos-storage Phobos is open source and a Lustre copytool is available. Archiving policies can be set up via Robinhood like with other HSMs. Robinhood is also open source and supports project IDs if you take the patches from GerritHub (like this one: https://review.gerrithub.io/c/cea-hpc/robinhood/+/541104 but more are needed, I can give you the list if needed). Data restore concurrency should be well handled with Lustre/HSM. A Lustre userspace coordinator named “coordinatool" is required for using Phobos in multi-server mode, but it is also freely available on GitHub. We plan to have a dedicated Lustre client for the coordinatool. Hope that helps.
