Chapter 3. Cabling the storage subsystem
After the storage subsystem is installed in its permanent location, you must cable it
to hosts, drives, and other external devices, depending on your hardware
configuration.
iSCSI controller connectors
Figure 13 shows controllers A and B, the host ports, and the drive expansion ports
on the iSCSI controllers.
Host port 1 and Host port 2
The iSCSI host ports are auto-negotiated 100/1000 Mbps Ethernet ports
that support iSCSI off load. The host ports also provide support for both
Internet Protocol version 4 (IPv4) and IPv6, and have the advanced
networking functions of jumbo frames, IEEE 802.1p, and virtual local area
network (VLAN) support.
Drive expansion port
The drive expansion port is a x4 multilane SAS port. Connect a SAS cable
to this port and to a drive expansion enclosure.
Enclosure ID settings
The controller automatically sets the enclosure ID number. You can change the
setting through the storage management software, if necessary. Both controller
enclosure ID numbers are identical under normal operating conditions.
The allowable range of enclosure ID settings is 0 through 99. However, for best
results, do not set the enclosure ID to 00 or any number less than 80. The DS3300
enclosure ID is normally set to a value of 85 at the factory.
