      CERN-IT Storage Services for protoDUNE SP
      Speaker: Xavier Espinal Curull (CERN)
      protoDUNESP-FNAL-IT-Meeting.pdf

      Executive Summary

      Storage resources:

      • Disk space allocated on EOS for NP04 and NP02: 1PB
        • e-groups based ACLs to control access rights for different activities and users, ie. DAQ endpoint with a few “writers”
      • Access granted on CASTOR for tape backup purposes
        • “lazy“ aggregation, cold storage behaviour

      Data access: 

      • Local users (batch and interactive): xrootd and FUSE data access available and exercised during last months. 
      • “Grid-like” workflows enabled: ACLs based on VOMS certificates fetch from DUNE VO plus some local overrides in place to steer np02 and np04 distributed data together
      • Gridftp doors dimensioned accordingly to fulfill future protoDUNE, scaled-out from 2x1GByte/s to 8x1GByte/s (reminder: this bandwidth is shared among all eospublic experiments) 
      • EOS and CASTOR endpoints linked: FTS/xrdcp used for data aggregation and data recalls
