5 Hardware Management PLC Systems 5 XFEL will have O(600) PLCs to be managed PLC devices control critical systems (e.g. cavity tuner and vacuum controls) System architecture has to be faulttolerant and maintainable High availability cluster with virtualized PLC management nodes Proven technology at FLASH for O(100) PLCs XEN-virtualized nodes on HA- LINUX Cluster Fault-tolerant features Easy maintenance Very robust

6 Management 6 Control System - Server programs, communication protocols, applications, commercial software and web services. - management has to support various stages in the lifecycle of the accelerator: - initial development and implementation, - commissioning phase and - production mode, where improvements and maintenance are dominating. In-house developed software, protocols and APIs Third-Party Applications Development Environment Code Repository Release and Package Management Distribution Documentation Documentation Distribution

7 Computer Infrastructure 7 Server Nodes Client Nodes Front-End Nodes Cluster Storage Systems Control Room Consoles User Desktops xtca Systems Central Services (Alarm, Name, File, Boot etc.) Online Disk Space Consoles for control systems operations Nodes for Control Systems Development and Operations PLC System Server Data Acquisition and Middle Layer Services Tape System (transparent) High Performance Nodes (Graphics) Other User Application Machines (Analysis) Server Console Systems

8 Infrastructure - Specifications 8 Requirements and Specifications Separation of control system and office network to ensure uninterrupted operations. Gateways to allow remote access for monitoring and expert interactions. layout accommodates physical and geographical distribution of system components. Dedicated high-speed links e.g. for uplink to IT-centre or between subsystem used for feedback purposes. Decouple control system network from off-site internet but allow remote expert access through secure connection.
