The rear of the controller enclosure can accommodate up to eight minihub canisters: Up
to four front end (host) and up to four back end (drive) minihubs (Figure 2-3). Each
minihub has two Fibre Channel connectors. You connect the host- or drive-interface
cables to the respective minihubs. For more information on these connectors, see the
sections "Diagnostic Interface Connectors" on page 19, "Host Interface Connectors" on
page 24, and "Drive Interface Connectors" on page 25.
