To connect a SAS host bus adapter (HBA) to the DS3200 storage subsystem,
complete the following steps:
1. Connect a SAS cable from the DS3200 RAID controller host port to the SAS
HBA that is in the host. Figure 13 on page 23 shows the location of the DS3200
host ports.
2. Create a redundant host connection:
v If the DS3200 is a single-controller storage subsystem, connect a SAS cable
from the second SAS HBA to another host port on the DS3200 RAID
controller. You can create a maximum of one redundant host connection to a
single-controller DS3200.
v If the DS3200 is a dual-controller storage subsystem, connect a SAS cable
from the second SAS HBA to a host port on the other RAID controller on the
DS3200. You can create a maximum of three redundant host connections to
a dual-controller DS3200.
See “Direct-attached single-controller connections” and “Direct-attached
dual-controller connections” on page 40 for illustrations of host connections.
