Installation Best Practices
Follow SCSI Best Practices
When installing an LTO-1 or LTO-2 tape drive, follow SCSI best practices to ensure trouble-free instal-
lation and operation.
SCSI Host Bus Adapters (HBA)
We strongly recommend that you attach the LTO-1 or LTO-2 tape drive to SCSI controllers that sup-
port the SCSI Ultra2 LVD interface and 160 MBytes SCSI transfer rate only.
In addition, do not
Attach the tape drives to a non-LVD SCSI controller, as this will degrade the performance of
•
the tape drive and the performance of your backups.
Attach non-LVD SCSI devices on the same bus cable, as this will degrade the performance of
•
the tape drive and your backups.
Connect the tape drive to a disk RAID controller, as this is not supported.
•
If you are installing an adapter, we recommend you use a SCSI LVD controller kit that includes the
SCSI cable and terminator.
If installing a SCSI HBA, be sure it is supported by your operating system and your backup software
application. In addition, ensure that you have the proper drivers for the HBA, if any are necessary.
Before you install the HBA, check and record your current system configuration. For example, in
Windows 2000, you may find information on any currently installed SCSI HBA by:
Double-clicking on Administrative Tools in the Control Panel.
•
Clicking on Computer Management > Device Manager.
•
Clicking on the SCSI host adapters listed.
