Query: SAN/AFS: Developments in Storage Data Systems on Frascati Tokamak
  Upgrade   In the last three years, the architecture of Frascati Tokamak Upgrade (FTU)
experimental database has undergone meaningful modifications, data and codes
have been moved from mainframe to UNIX platforms and AFS (Andrew File System)
has been adopted as distributed file system. Further improvement we have added
regards data storage system; the choice of SAN (Storage Area Network) over
Fiber Channel, combined with power and flexibility of AFS, has made data
management over FTU very reliable. Performance tests have been done, showing
better transfer rate than previous system, based on JBOD modules with SCSI
connection.
