In early 2013 the Tier1 prototype was developed and its trial operation began. March, 2015 is the date of finalization of this complex and commissioning a full-scale Tier1 centre for СМS in JINR. During all time it has continuously adapted to the new requirements, introducing new hardware and technologies as they became available, and it has grown significantly in resources offered to the CMS experiment to be on top reliability levels as compared to other Tier1’s processing data for CMS.
Special Tier1 network centre was developed, providing scalability of its network infrastructure. Additional work has been done in the last years to hardware and service monitoring. Future modernization and raising of the Tier1 performance will provide possibilities of efficient and rapid processing and storage of data from the CMS experiment at LHC for work at high luminosity and increasing energy collisions.
The report of Strizh T. A. was presented at the conference GRID-2018
