Abstract: With the construction and application of various information systems constantly, the monitoring data generated by the information system increases in series.It becomes a new challenge for enterprises that how to Efficiently storage and real-time analysis and processing of massive operation and maintenance data. Therefor, this paper proposes a solution of IT operation and maintenance data management system based on big data technology,which divides the data management system into four layers: data integration, data storage, data calculation and data access,they are independent but also cooperative, for giving full play to the advantages of large data technology in data storage, parallel computing, large-scale data analysis, mining and other aspects. The solution provides efficient processing ability and unified data management mode for the storage of mass data in Information Center, and fully supports the application of data analysis, so as to promote the construction of intelligent operation and maintenance.

Key words: big data, IT operation and maintenance, data management, data mining
