IMPORTANT:
Deciding which HBA and cabling configuration to use with external drives is a complex choice and
supported configurations are constantly being updated. Always refer to h

to fi nd out which cabling option is appropriate for your combination of server and tape drive and
whether hard disk drive bays will be disconnected.
Select tape backup and navigate down to the Ha rdware Compatibility table for your make of ser ver.
The server/tape drive matrix shows top-level compatibility, but be sure to click on the box for your
combination of server and tape d rive to display a further page with detailed connectivity information.

The supplied, split cable is threaded through the rear panel of the server and requires a spare PCI slot to
accommodate the cable bracket and SAS connector to the tape drive.
I
f you install a new HBA and it supports only an internal SAS connection, you can use the cable supplied
with the tape drive to connect to the internal por t. You require sufficient spare PCI slots to acc ommodate
