Controller unit interface ports
The host and drive GBIC mini-hub ports are used to attach cables from the controller and
drive enclosures to the storage subsystem. There are also Ethernet ports for storage
subsystem- management and RS-232 (serial) ports for diagnostic services. The controller
unit interface ports are shown in the following figure.

Host interface ports
Host mini-hubs connect to the controller in pairs. Mini-hubs 1 and 3 connect to the top
controller (Controller A) and mini-hubs 2 and 4 connect to the bottom controller
(Controller B), as shown in

connect each host to both controllers through the appropriate mini-hub.
