Abstract: With the gradual deepening of railway informationization, the massive data generated by various railway businesses brought challenges to storage, management and effective utilization data. In order to allocate storage resources reasonably, maximize the value of railway big data, realize the refinement and intelligence of data center management, reduce the complexity of data center management, this article put forward the design scheme of railway big data storage and management system, described the system architecture, the technical scheme, the design and implementation of system functions in detail. The system effectively reduced the work intensity of operation and maintenance personnel, improved work efficiency, and the automation and intelligence of data center management.
