4 Cabling the ATL M2500 Library for Fibre Channel

Cabling the ATL M2500 Library for Fibre Channel 0

The cabling configuration used for the ATL M2500 library with the

FC420 option depends on the following factors:

• Number of tape drives installed

• Tape drive type (DLT8000, SDLT, or LTO)

• Number of FC420 Fibre bridges installed

• Data transfer rate of the storage area network (SAN)

One- and Two-Drive

Library Cabling

If the ATL 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.
