• Operational interventions including HW and pool failures

  • ATLAS utilizes tokens for transfers, and DATADISK and SCRATCHDISK have been migrated to the CERN FTS Pilot instance

  • USATLAS storage upgraded to dCache 9.2.6 + java-17 (1/22)

    • https://ggus.eu/index.php?mode=ticket_info&ticket_id=165029

    • While initially a temporary workaround is in place to overcome the issue. Most recently refreshing the state of components appeared to help as the occurrence of the issue appeared to be reduced.

    • Issues found and reported www.dcache.org #10575 configuration instabilities observed wrt. WAN TPC writes.

  • Configuration for RHEL8 (HPSS, dCache pools) is ready. New data servers just delivered to start their commissioning, etc

  • 1000 LTO8 tapes (= 12 PB) purchased and delivered to BNL receiving
  • Procurement process of FY24 storage for ATLAS started

  • Data challenge 24 preparation:

    • Stress-testing and performance evaluation of USATLAS storage (tuning, etc.) with dedicated FTS servers

    • Joint USATLAS-USCMS site transfer stress testing (1/24):

      • Achieved WAN READ throughput surpassing 400 Gb/s.

      • No issues were identified on core, doors, and pools servers regarding CPU, memory, or load. Traffic distribution among the pools is uniform
