Single-Ported (Non-failover) Configuration
Figure 2-1 shows a simple single-ported (non-failover) configuration consisting of one host (X), two adapters (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 adapter 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 2-1 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 adapters are connected to which target devices. This is not a failover configuration; each target device is accessible through only one adapter.
