Q
Figure 2-1. Single-Ported Configuration
Note that figure 2-1 simplifies hardware connections: target devices can be
connected through a local loop, Fibre Channel hub, Fibre Channel switch, or any
combination of those. Fibre Channel topology is useful in troubleshooting situations;
however, a basic configuration requires only this basic diagram showing which hosts
and HBAs are connected to which target devices. This is not a failover configuration;
each target device is accessible through only one HBA.
2.2.2
Simple Failover Configuration
Figure 2-2 shows a simple failover configuration consisting of one host (X), two
HBAs (A and B), three dual-ported devices (0–2), and two single-ported
devices (3–4).
