26. Summary RDMS Tier2 sites contribute in the CMS Data Processing and Analysis Tasks  Tier-2 sites are satisfied to CMS Computing Requirements  they are involved actively into data processing and analysis (as of CMS Physics Groups associated sites)  CMS Regional Operation Centers in JINR/MSU/IHEP/FIAN are operated for remote monitoring of detector systems and data express- analysis There is still a number of problems (technical, financial etc.) preventing RDMS Tier2 sites to increase their resources and operation stability A stable and successful operation of several RDMS CMS Tier2 centers and years of operating experience lead to creation the CMS Tier-1 center in Russia as an integral part of the central data handling service of the CMS Experiment (CMS Tier-1 in Dubna)
