1 Gbps iSCSI host ports
The 1 Gbps 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 storage enclosure.
Controller connectors (with 10 Gbps iSCSI host port adapters)
Figure 3-3 shows the optional 10 Gbps iSCSI host port adapter installed in both controllers at the rear of
the DS3500 storage subsystem.
10 Gbps iSCSI host ports
The 10 Gbps iSCSI host ports are auto-negotiated 1/10Gbps 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.
