STIX Data Center hardware architecture and data flow. Solar Orbiter telemetry data are processed at the Mission Operations Center (MOC) and delivered to the instrument team via the generic file transfer system (GFTS). The STIX Data Center currently utilizes five servers: one for data exchange, two for running the data-processing pipelines, one for the web server, and one for data storage (network attached storage or NAS). STIX data products are stored on the NAS server. The data exchange server is also used to deliver instrument operations requests (IORs) to the MOC, and payload direct operation requests (PDORs) to the Science Operations Center (SOC).
