The dCache project at Brookhaven Lab provides an open-source storage software solution and is a joint venture involving Deutsches Elektronen-Synchrotron (DESY), Fermi National Accelerator Laboratory (FNAL), and the Nordic e-Infrastructure collaboration (NeIC). 

dCache aggregates multiple storage types (disk or tape, e.g., Mass Storage System/BNL HPSS system) into a single storage system and manages data movement, replication, and integrity. dCache supports several access protocols, including https or posix.

Several instances are deployed at BNL for various experiments:

  • ATLAS (the largest instance at BNL)
  • Belle-II
  • s-PHENIX
  • Deep Underground Neutrino Experiment (DUNE)

Problem Reporting

To report any problems or requests, please open an RT ticket in StorageManagement queue ( and include as much relevant information in the report as possible.
