Abstract: The IT system for space trial mission must be high-performance, high stability, high security and scalable computer network architecture, In order to support the need for continuous updating, upgrading and development in the future, and ensure the smooth implementation of the aerospace test task. According to Characteristics and technical requirements of IT operation and maintenance for cloud data center of Aerospace test system, With the domestic self controlled hardware and software as the core, Adopt subsystem, hierarchical, modular design concept of system architecture, Building an all open, component-based architecture prototype, Integration of resource monitoring, automation operation and maintenance, operation and maintenance process management, Build a reliable, scalable and high-performance solution for integrated IT operation and maintenance management. Escorting the stable operation of the space trial mission system.
