Chapter 20 iSCSI Configuration
Configuring iSCSI
Multiple IPS Ports Connected to the Same IP Network
Figure 20-12 provides an example of a configuration with multiple Gigabit Ethernet interfaces in the
same IP network.
Figure 20-12 Multiple Gigabit Ethernet Interfaces in the Same IP Network
In Figure 20-12, each iSCSI host discovers two iSCSI targets for every physical Fibre Channel target
(with different names). The multi-pathing software on the host provides load-balancing over both paths.
If one Gigabit Ethernet interface fails, the host multi-pathing software is not affected because it can use
the second path.
