Abstract: High current linear induction accelerator (LIA) is mainly used in flash photography experiment , the success or failure of which is directly affected by the stability and reliability of the control system. At present, there are many back-end control hosts scattered in positions in the control system, which brings difficulties in centralized management and control. Furthermore, there is no redundant design in the control system. These factors are potential risks and may affect normal operation of the accelerator. In this paper, virtualization + FC SAN technology are used to build a virtualization control platform. The software and hardware are scalable and support high availability(HA). In the platform management, the management of cluster and data center are realized, and the functions of creating, cloning, migration and snapshot of virtual machines are supported. In the system monitoring, scheme wsith Zabbix and Grafana is used to develop monitoring application for servers, virtual machines and network, providing concise and clear visual interface. In terms of business functions, virtual machines are used to replace IOCs host equipment to realize all functions of back-end control. Relying on HA of platform architecture, redundant design is provided for the control system to solve the operation risks of the accelerator. In addition, applications such as PV monitoring and alarm, PV information archiving, are developed to realize information monitoring, historical data archiving and query of critical equipment in the control system. The application of virtualization platform improves the stability and reliability of the control system of high-current linear induction accelerator, and enhances ability of management and control of devices and ability of data visualization.
