Liang-Jui Shen, Dexue Liu, Tsung-Yueh Wan · 2011
In large scale distribute control system, there are lots of common service composed an environment for the entire control system, such as the server system for the common software base library, application server, archive server and so on. This paper gave a description of a virtualization realization for control system environment include the virtualization for server, storage, network system and application for the control system. With a virtualization instance of the epics based control system environment that built by the VMware vSphere v4 [1], we tested the whole functionality of this virtualization environment in the SSRF [2] control system, include the common server of the NFS, NIS, NTP, Boot and EPICS base and extension library tools, we also virtualization the application server such as the Archive, Alarm, EPICS gateway and all of the network based IOC. Specially, we test the high availability (HA) and VMotion for EPICS asynchronous IOC successful under the different VLAN configuration of the current SSRF control system network.
