Abstract: HL-2M network and data management includes experimental network system, data storage and 
backup, experimental database and experimental information management, etc. The network system is the 
supporting framework of the device operation, providing the interconnection channel and signal transmission for 
each sub-system. Data storage and backup system provides data storage management and disaster recovery 
backup for tokamak experiment. The experimental database system provides efficient retrieval, access and 
management for metadata and scientific data. Experimental information management system provides parameter 
configuration management, operation logging and operation duty management for each sub-system of the device, 
which realizes the informatization of experimental operation management and improves the efficiency of 
experimental operation. 

Key words: HL-2M tokamak, Data storage and backup, Experimental network system, Information management system
