iSCSI High Availability
Figure 50-39 Multiple Gigabit Ethernet Interfaces in the Same IP Network
In Figure 50-39, 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.
VRRP-Based High Availability
Figure 50-40 provides an example of a VRRP-based high availability iSCSI configuration.
