Using a Serial-attached
SCSI Host Bus Adapter
LTO-3 Half-Height Tape Drive User's Guide
the LTO-3 Half-Height Tape drive would degrade the performance of the
drive and your backup operations.
Caution: Never connect the LTO-3 Half-Height Tape Drive to a
disk RAID controller. This is not supported.
If you must use a SCSI host bus adapter (HBA), always:
• Use a dedicated SCSI HBA to enable the best performance and reduce
the chance of installation difficulties that might be caused by
duplicate SCSI IDs on the same bus channel.
• Use a SCSI LVD controller kit that includes a high-quality SCSI cable
and terminator that conforms to Ultra 2 SCSI specifications. A low-
quality cable, or a cable that does not conform to the Ultra 2 SCSI
specifications can cause intermittent write/read errors, SCSI
timeouts, and corrupted data.
• Make sure that:
• Your operating system supports both the adapter and your
backup software application.
• You have the proper drivers for the HBA, if any are necessary.
To achieve the very best performance from your serial-attached SCSI

operations, always attach the drive to a serial-attached SCSI controller
that supports 3 GBytes per sec. per port transfer rate.
