PoS(ISGC&HEPiX2023)005Extension of local dCache instance capacity using national e-infrastructure J. Chudoba The Czech WLCG Tier-2 center for LHC experiments ATLAS and ALICE provides computing and storage services for several other Virtual Organizations from high energy and astroparticle physics. The center deployed Disk Pool Manager (DPM) for almost all (only ALICE VO uses xrootd servers) supported VOs as a solution for storage until recently. The local capacity was extended by a separate instance of dCache server which was operated by CESNET Data Storage unit in a remote location. The exact location has changed during the project, the distance was between 100 to 300 km. This storage extension was based on HSM and was mapped as a separate ATLAS space token where higher latencies were expected.
