Cabling the M2500 Library for Fibre Channel
Cabling the M2500 Library for Fibre Channel
0
The cabling configuration used for the M2500 library with the FC420
option depends on the following factors:
• Number of tape drives installed
• Tape drive type (SDLT or LTO)
• Number of FC420 Fibre bridges installed
• Data transfer rate of the storage area network (SAN)
One- and Two-Drive
Library Cabling
0
If the M2500 library has only one or two tape drives, the cabling is the
same regardless of drive type or SAN. One- or two-drive libraries only
require one FC420 Fibre bridge.
Figure 1
shows the cabling for a one-drive library.
Figure 1 One-Drive
Cabling
As shown in the figure, a SCSI daisy chain is established from one of
the SCSI ports on the FC420 to the SCSI controller and then to drive 0,
where the daisy chain is terminated. The SCSI controller is included in
the chain to pass SCSI commands to the robot.
The SCSI controller and drive 1 must be on the same SCSI bus because
the SCSI controller has termination disabled.
