dCache, Bridging Between Sync-n-share and Compute Cloud
Patrick Fuhrmann, Alexander Paul Millar · DESY (CERN, DESY, Fermilab, IHEP, and SLAC) · 2015
How we solved it at DESY• Looked around, chose two open-source projects:• dCache: powerful managed storage system Integration with scientific data life-cycle; "Hot" data can be stored on SSDs, "cold" on cheaper HDDs, "archive" tape; … but no sync and share facilities.• ownCloud: popular front-end Our collaborators adopting ownCloud makes it more attractive; … but assumes storage is managed.• Combining these two gives DESY the best of both worlds: dCache is mounted on servers with NFS v4.1/pNFS, running community edition ownCloud.Integrated with DESY Kerberos, LDAP and "Registry".
