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.
The drive expansion port is a x4 multilane SAS port. Connect a SAS cable
to this port and to a drive expansion enclosure.

The DS3500 host ports are each a x4 multilane, 6 Gbps universal mini-SAS
port. Connect a SAS cable from your host system SAS host bus adapter to
a host port on each controller.
