Basic Configurations with Hubs
The basic configurations with hubs are shown in Figure 1-1 and Figure 1-2. Each of
the configurations contains a single host bus adapter in each server and a single hub.
Single Storage Controller
Figure 1-1 shows a configuration with a single connection between the hub and the
storage controller. Failures in the server, server software, host bus adapter, or cable
from the host bus adapter to the hub will cause Microsoft cluster software failover to
the second server, and the cluster will continue to service data requests from the
second server.
NOTE: The dashed lines indicate maximum configuration.
