HP SAS tape drives are available as internal and external models. Both models are supplied with SAS
cables that allows you to connect to an internal port (if available) on the embedded SAS controller inside

cables that allows you to connect to an internal port (if available) on the embedded SAS controller inside
the server.
Some server models will allow direct connect to a spare SAS connector on the native SAS controller.
Other servers which do not have a spare connector might require you to reconfigure hard disk drive bays
and in a few instances, you may also lose the use of one of the hard disk drive bays and will need to
rebuild your RAID configuration. In these configurations the simple, recommended solution is connecting
to an option SAS host bus adapter and optional SAS cable.
