Cabling the Library for Fibre Channel 5
One- and Two-Drive
Library Cabling
0
If you are cabling an ATL M1500 library, or an ATL M2500 library with only
one or two tape drives, the cabling is the same regardless of drive type or
SAN. One- or two-drive libraries require only one FC420 bridge.
Figure 2 shows the cabling for a one-drive library.
Figure 2 One-Drive Library
Cabling
In a one-drive configuration (as shown in figure 2 ), a SCSI daisy chain is
established from one of the SCSI ports on the FC420 bridge to the SCSI
controller and then to drive 1, 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.
Note:
HP LTO Gen 2 and SDLT 600 require 2 GB SAN connections. All
other drive types may have either a 1 GB or 2 GB SAN connection.
