  Shanghai Synchrotron Radiation Facility (SSRF) use a 150 MeV linear electron accelerator as injector, its RF system consists of many discrete devices. The control system is mainly composed of a VME controller and a home-made signal conditioner with DC power supplies. The uniform signal conditioner serves as a hardware interface between the controller and the RF components. The DC power supplies are used for driving the mechanical phase shifters. The control software is based on EPICS toolkit. Device drivers and related runtime database for the VME modules were developed. The operator interface was implemented by EDM.

  In a large scale distribute control system, there are lots of common services composing an environment of the entire control system, such as the server system for the common software base library, application server, archive server and so on. This paper gives a description of a virtualization realization for a control system environment, including the virtualization for server, storage, network system and application for the control system. With a virtualization instance of the epics based control system environment built by the VMware vSphere v4, we tested the whole functionality of this virtualization environment in the SSRF control system, including the common server of the NFS, NIS, NTP, Boot and EPICS base and extension library tools, we also carried out virtualization of the application server such as the Archive, Alarm, EPICS gateway and all of the network based IOC. Specially, we tested the high availability (HA) and VMotion for EPICS asynchronous IOC successfully under the different VLAN configuration of the current SSRF control system network.
