The Cornell Electron Storage Ring (CESR) accelerator complex is used to support the Cornell High Energy Synchrotron Source (CHESS) x-ray user facility and the CESR Test Accelerator (CESRTA) ILC development program. Several hundred electro-magnetic elements as well as several thousand sensors are controlled and monitored in real-time via a Multi-Port Memory device (MPM). MPM access and control programs have used Hewlett Packard (originally DEC) Alpha and VAX computers running OpenVMS since 1988. Due to the demanding throughput, computational and storage requirements of the CESRTA experimental program, as well as a desire to upgrade to more supportable hardware, we have implemented a new Linux control cluster based on an Infortrend 10 GbE Internet Small Computer System Interface (iSCSI) storage device and the Red Hat Cluster Suite. This paper will describe the hardware and software changes required to upgrade our VMS cluster to a high availability, high performance, Linux control cluster.
