Description
The BNL Computing Facility Revitalization (CFR) project aimed at repurposing the former National Synchrotron Light Source (NSLS-I) building (B725) located on BNL site as a new data center for Scientific Data and Computing Center (SDCC). The CFR project finished the design phase in the first half of 2019, completed the construction phase by the end of FY2021, and entered the early occupancy phase in Jun-Aug 2021. The occupancy of the B725 data center for production CPU and DISK resources of the ATLAS experiment at the LHC at CERN, STAR, PHENIX and sPHENIX experiments at RHIC Collider at BNL, the Belle II Experiment at KEK (Japan) started in 2021Q4 and ramped up in 2022Q1 to the level of 40 racks populated with equipment in the B725 Main Data Hall (MDH). At the same time, two library rows in B725 Tape Room were populated with IBM TS4500 tape libraries serving ATLAS and sPHENIX experiments. The occupancy of B725 MDH is expected to further increase to 70 racks by the end of FY2022. The new HPC clusters and storage systems of BNL Computational Science Initiative (CSI) are to be deployed in B725 data center starting from early FY2023 as well. The transition of the SDCC data center environment for using B725 data center for hosting the majority of CPU and DISK resources, and leaving the old (B515 based) data center for hosting predominantly TAPE resources, is expected to continue until the end of FY2023. In this talk I am going to summarize the main design features of the new SDCC datacenter, report on how the transition to B725 data center occupancy was carried out in 2021Q4-2022Q1 time frame, and highlight the plans for scaling up the occupancy and infrastructure utilization for both old and new data centers up to FY2026.
