Installing in a tape array
Appropriate HP rack-mount systems
HP LTO Ultrium removable tape drives can be used with any compatible rack-mount tape array system.
The tape array is designed to be installed into any compatible 19” rack-mount systems. It must be
properly installed and configured. Refer to your tape array documentation for further details.
Airflow requirements
As long as the tape array is fully populated, it will provide adequate airflow for HP LTO Ultrium 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.
HP LTO Ultrium drives require forced airflow as detailed below.
Full-height drives:
The required airflow depends on the ambient air temperature and should be from back to front:
• 6 cfm for ambient air temperatures fluctuating in the range 10°C–35°C.
• 8 cfm for ambient air temperatures fluctuating in the range 10°C–40°C.
For details of how to test if the airflow is adequate, see “Airflow requirements” on page 16.
Half-height drives:
The required flow is 5 cfm for ambient air temperatures fluctuating in the range 10°C–40°C, and
must be from front to back.
Identifying the drive
The model name is on the front panel and the product and serial numbers are on a label attached to
the drive.
Modes of usage
Tape arrays can be used in different system configurations; direct attach, network attach and attached
to a Storage Area Network (SAN). For details of these see “Modes of usage” on page 47.
Attaching to SAS
HP LTO Ultrium SAS drives are high performance 6 GB SAS devices. When installed in a tape array
in a compatible rack mount system they can be connected to a SAS connection on a server or to an
expander as part of a larger SAS network. To get the optimum performance from your tape drive you
need a SAS topology that can transfer data at a rate that supports the tape drive’s maximum transfer
speed.
