.
The cable supplied with the tape drive is suitable for connecting to a dedicated HBA.
An alternative option for HP ProLiant servers is to connect to the server's SAS controller.
•
If the host SAS controller has a mini-SAS connector, the supplied cable may be used to connect
the tape drive.
•
If it has an Infiniband-style connector, you must purchase a different cable.
NOTE:
All non-HP servers require a dedicated HBA.
Table 5 Cables for the SAS internal tape drive
Cable required
Connector type
HP SAS cable (Part number AP747A)
To a dedicated HBA (recommended installation)
HP SAS Infiniband split cable (Part number
406594–002)
To an internal Infiniband-style SAS connector
HP Mini-SAS split cable (Part number AP747A)
To an internal Mini-SAS connector
CAUTION:
HP SAS cables contain four data paths, which normally support up to four hard disks. When used to
connect to the host SAS controller, both the HP SAS Infiniband and the HP Mini-SAS split cables divert
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 using this cabling configuration because you may lose the use of one
of your hard disk drive bays.In a few instances, it may be necessary to recable hard disk drive bays.
If this is unacceptable, you must purchase and install a separate, supported HBA for the tape drive
with appropriate cable. See
