Figure 4-37 Example of a single Fibre Channel SAN fabric configuration
Cross connected dual SAN fabric
Figure 4-38 on page 131 is an example of a configuration using a cross-connected dual SAN
fabric (also known as mesh). In a cross-connected SAN fabric, each host bus adapter has a
connection to both controllers in a dual controller DS3500 storage subsystem. Some
applications and host operating systems require a cross-connected SAN fabric.
