Installing the storage subsystem configuration
Using the information from the previous sections, install the host systems, and
either hardware or software iSCSI initiators.
Notes:
1. See the documentation that comes with the hardware and software initiators for
installation requirements and procedures.
2. Use the correct HBA device driver. For the latest supported HBAs and device
drivers, go to http://www.ibm.com/servers/storage/support/disk/
Attach the cables to each host. Continue to “Connecting hosts to the DS3300” to
connect the other end of each cable to a controller.
Connecting hosts to the DS3300
The DS3300 can support up to 16 hosts, depending on the number of host ports
and host partitions that are used on the DS3300 RAID controller. To protect against
the loss of any one path from the host servers to the DS3300 storage subsystem,
use redundant host connections.
To connect a hardware or software iSCSI initiator to the DS3300 storage
subsystem, complete the following steps:
1. Connect a Category 5e or Category 6 Ethernet cable from the DS3300 RAID
controller host port to a gigabit Ethernet switch, and then connect an Ethernet
cable from the switch to the hardware or software iSCSI initiator port that is in
the host. Figure 13 on page 23 shows the DS3300 host ports.
