2. Create a redundant host connection:
v If the DS3300 is a single-controller storage subsystem, connect an Ethernet
cable from the second host port on the DS3300 RAID controller to a gigabit
Ethernet switch.
v If the DS3300 is a dual-controller storage subsystem, connect an Ethernet
cable from the host port on the other RAID controller on the DS3300 to a
gigabit Ethernet switch.
Notes:
1. Do not configure any two interfaces on the same subnet.
2. If you are using DHCP on more than one interface, multiple interfaces can end
up on the same subnet.
For illustrations of host connections, see “DS3300 single-controller connections” and
“DS3300 dual-controller configurations” on page 40.
DS3300 single-controller connections
The following illustration shows a single controller DS3300 that is attached to a
single host. This configuration has no redundancy.
A system with dual iSCSI ports can provide enhanced performance compared to a
system that uses only one iSCSI port.
