Control Path and Data Path Configuration
The Silo Media Manager solution consists of a SCSI control path, plugged into either a
PMFC or the ServerNet/DA S-SAC and 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 to either the PMFC or the ServerNet/DA S-SAC and
directly to a tape drive. The SMM GUI interface runs on a PC and uses TCP/IP to
communicate with the NonStop system.
Commands sent from the SMM GUI via TCP/IP are intercepted by the Silo Media
Manager process running on the NonStop system. The process then sends the
commands via the control path to the tape library.
