Requirements; Mounting Requirements; Server Connections - HP LTO Ultrium Technical Reference Manual

Requirements

Mounting requirements

• Half-height drives require one industry standard 5¼-inch, half-height bay.
• Full-height drives require one industry standard 5¼-inch, full-height bay.
HP recommends 0.3 mm mounting clearance around all covers for isolation mounting movement.
For many servers, no mounting tray or rails are required. Devices simply slide into the computer's
chassis and are fixed with screws. Other servers have built-in trays or rails. Yet others require a special
mounting tray or rails to fix the drive into the empty bay.
Refer to your server documentation for details on how to install drives.

Server connections

You need a properly installed and configured SAS host bus adapter (HBA) or a built-in SAS controller
on the server.
The SAS drives have a 6 GB SAS interface, and are designed to work with most SAS devices. The 6
GB SAS interface supports a maximum bus speed of 600 MB/s, as opposed to the 150 MB/s of the
1.5 GB SAS interface. Therefore, installing the drive onto a 1.5 GB bus is not recommended as this
may restrict performance.
For optimum performance, use a dedicated host bus adapter for the tape drive.
Do not connect to a RAID controller channel; these are for disk drives only. Consult your supplier for
details.
For a SAS internal drive, you will need:
• 6 GB SAS host bus adapter or the server's embedded HBA
• SAS-compliant cable
• Mounting hardware, if required
• Backup software that supports the tape drive
