The requirements for SAS bus connections are different than for the
SCSI bus. Each tape drive is required to have a dedicated bus to the
initiator, referred to as point-to-point connection. SAS architecture does
not support multiple tape drives connected to a single host adapter
port. The maximum SAS cable length that can be used to connect the
host adapter to the tape drive is 5.5 m.
To connect the cable:
1 Ensure the tape drive is powered OFF.
2 Since there are several types of SAS connectors, verify the SAS cable
has the correct connectors for the SAS host adapter and for the tape
drive.
3 The tape drive has two SAS ports and can be connected to two
servers, if desired. Refer to the appropriate figure that represents
your configuration for cabling information (see
or
Figure 6
on page 26) and then connect the SAS cable(s) to SAS
host adapter(s) and to the tape drive as shown.
