Considerable attention is paid to the activities in frames of the Russian node of the Grid network, in which JINR plays a role of one of the centers for modeling and analysis of the data of the ATLAS experiment. The involvement of JINR in the ATLAS TDAQ and Data Quality Monitoring Framework is under consideration, the history of the creation at JINR of a remote access system (Remote Control Room). Described is the development (in the field of Distributed Data Management) of the service of deleting unnecessary or damaged data (Data Deletion Service) on the sites Tier0-Tier1-Tier2 which ensures the integrity of storing information in a geographically distributed environment. Attention is paid to the creation of grid-nodes of the Tier3 level for a physical analysis on the local resources.
