Control Path and Data Path Configuration with CTL700
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 tape library.
The Control path is the path responsible for tape cartridge movement and library
control. The Data path is for tape drives.
The Data path is connected the same way the tape 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.

Note. The client can also be a NonStop S-series system.
Note. If the CTL700 tape library has a Fibre Channel interface instead of a SCSI interface, no
M8201 will be needed. The control path will connect via Fiber only.
