Control Path and Data Path Configuration
The Library Media Manager solution consists of a Fiber/SCSI control path. It is plugged
into a Fibre Channel ServerNet adapter (FCSA), and then to a Fibre Channel to SCSI
router (M8201), and then it connects via SCSI directly to the library. The Control path is
the path responsible for tape cartridge movement and library control. The Data path, on
the other hand, is for tape drives.
The Data path is connected the same way the library is for SCSI tape drives, it is
connected by fiber only for Fibre Channel tape drives . The LMM GUI runs on a PC
and uses TCP/IP to communicate with the NonStop NS-series server.
Commands sent from the LMM GUI via TCP/IP are intercepted by the Library Media
Manager process running on the NonStop NS-series server. The process then sends
the commands via the control path to the tape library.
