SEARCH FOR A RELIABLE STORAGE ARCHITECTURE FOR RHIC.
Software used to operate the Relativistic Heavy Ion Collider (RHIC) resides on one operational RAID storage system. This storage system is also used to store data that reflects the status and recent history of accelerator operations. Failure of this system interrupts the operation of the accelerator as backup systems are brought online. In order to increase the reliability of this critical control system component, the storage system architecture has been upgraded to use Storage Area Network (SAN) technology and to introduce redundant components and redundant storage paths. This paper describes the evolution of the storage system, the contributions to reliability that each additional feature has provided, further improvements that are being considered, and real-life experience with the current system.
