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.

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
