I/O modules

Two I/O modules provide the interface between the drive enclosure and the host controllers. See
Figure 12. They route data to and from the disk drives using Loop A and Loop B, the dual-loop
configuration. For redundancy, only dual-controller, dual-loop operation is supported. Each controller
is connected to both I/O modules in the drive enclosure.
