5 Installing a removable DAT tape
drive
If you are installing an internal DAT tape drive, please refer to
“ Installing an internal DAT tape drive ” on page 19.
If you are installing an external DAT tape drive, please refer to
“ Installing an external DAT tape drive ” on page 29.
Which rackmount systems can I use?
HP StorageWorks DAT removable tape drives are used in conjunction with the HP Tape Array 5300
system, which can be used with both full-height and half-height tape drives. It will hold up to four HP
StorageWorks DAT tape drives. The tape array is designed to be installed into HP, IBM and other
compatible 19” rackmount systems. It must be properly installed and configured. Refer to your tape
array documentation for further details.
Airflow requirements
The HP Tape Array 5300 is designed to provide adequate airflow for up to four half-height or up to two
full-height tape drives. As long as the tape array is fully populated, it will provide adequate airflow for
your HP StorageWorks DAT tape drives. If you have unused bays in the tape array, you must install the
blanking plates provided with the tape array. This ensures that there is adequate airflow to the drives.
See the documentation with the tape array for details on installing blanking plates.
You should ensure that ventilation is adequate at the front and rear of the tape array.
How do I connect the drive to my server?
The following guidelines apply:
• For optimum performance the drive should be the only device on the SCSI bus.
• If you daisy-chain devices, make sure that devices are of the same SCSI type and that each device
on the same SCSI bus has a unique SCSI ID and is terminated appropriately. Do not daisy-chain
more than two devices on the same SCSI bus (for example, two LVD Wide Ultra drives).
• Always terminate the SCSI bus.
• Do not attach the drive to the same SCSI bus as a your disk drive or to a RAID controller.
The individual tape drives are connected to their host server via the high density LVD/SE SCSI connectors
on the back of the tape array. They do not require any SCSI cables to plug into the tape array. However,
suitably-rated cabling and terminators are required to connect the tape array with the SCSI host.
NOTE:
HP StorageWorks DAT removable drives do not have termination power enabled, termination must be
supplied by the host.
