Single-Ported (Non-failover) Configuration

Figure 3-1
one host (X), two HBAs (A and B), and ten target devices (0–9). This
configuration assumes that the host has access to all connected devices;
therefore, it requires an HBA operating system driver, but does not require the rest
of SANsurfer FC HBA Manager. Other SANsurfer FC HBA Manager components
help manage devices more easily.

Figure 3-1 Single-Ported (Non-failover) Configuration
This illustration simplifies hardware connections: target devices connect through a
local loop, FC hub, FC switch, or any combination of those. FC topology is useful
in troubleshooting situations; however, a basic configuration requires only this
simple 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.
