Connecting SCSI, SAS, or Fibre Channel and Power Cables 13
SuperLoader 3
Note: The maximum number of autoloaders supported per SCSI bus is two.
The autoloader may not work with multiple
SCSI LUNs when attached to a RAID
controller. The autoloader is not recommended for use with a RAID controller. If
this situation occurs, it is recommended that the autoloader be attached to a
separate SCSI bus controller on the host or server.
Connecting SCSI, SAS, or Fibre Channel and Power Cables
To connect the SCSI, SAS (Serial Attached SCSI) or Fibre Channel and power cables to the
autoloader, refer to the following sections:
SAS 1 and SAS 2
Connectors
The type of SAS connector on the back of the SuperLoader (SAS 1 or SAS 2) depends on
the type of tape drive.
•
LTO-3 and LTO-4 Tape Drives SAS Connectors
• LTO-5 Tape Drive SAS Connectors
LTO-3 and LTO-4 Tape Drives SAS Connectors
SuperLoader 3 systems with LTO-3 or LTO-4 tape drives (including Model B versions)
contain a SAS 1 connector (see Figure 10
).
Figure 10 SAS 1 Connector
Connector shown outside of
system for clarity.
Only connect SAS 1 cables that are no longer than 4 meters when connecting to a SAS 1
connector.
Note: SAS 2 cables that are over 4 meters in length cannot be used with SAS 1
connectors. Quantum recommends using SAS cables that are no longer than 4
meters when connecting to a host.
