Chapter 2 — Architecture Overview
Dual-Port Connectivity As an alternative to the configurations that use a
single port for each partition, dual‐port configurations use both interface
ports as a single communications path to the same partition. The ports can
be connected to the same or different SANs. The hosts on the network can
use either port to communicate with the robotics. A dual‐port
configuration allows a host to have an alternate, redundant, path to reach
the partition. Not all host software can support this type of configuration.

 The two ports cannot be used simultaneously.
Notes:
 This type of configuration cannot be used in combination
with the Controller Failover feature (see Controller Failover
on page 78).
