HP StorageWorks DAT SAS Tape Drives User Guide (DW092-90918, June 2010)

CAUTION:
HP SAS cables that connect to an internal port are split cables that contain four data paths, which
normally support up to four hard disks. When used to connect to the host SAS controller, the split
cable diverts one of these data paths to the tape drive, which means that the data path is no longer
available for a hard disk drive. Take care if connecting to an internal port on the host SAS controller
because you may lose the use of one of your hard disk drive bays.
For detailed instructions on connecting the external SAS tape drive, see
“Installing an external DAT SAS tape drive” on page 37.

What are the mounting requirements for an internal tape drive?
Mounting bay
You need one industry-standard, 5¼-inch, half-height bay in which to install the HP StorageWorks
DAT tape drive.
Mounting hardware
For many servers, no mounting tray or rails are required. Devices simply slide into the server's chassis
and are fixed with screws. Other servers have built-in trays or rails.
Rail kits for a number of industry-standard servers may be available. For more details refer to: http:/
/www.hp.com/go/connect.
Some servers use non-standard mounting rails and do not include spares. If this is the case with your
system, you will have to order these accessories from the server manufacturer before you can install
the tape drive.

The HP StorageWorks Tape CD-ROM is a central source of information about your tape drive with
