Example: Dual-controller RAID Chassis with 7 Expansion Chassis
The following figure shows a dual-controller RAID chassis cabled to 7 expansion chassis featuring dual-
expansion I/O modules. Controller I/O module 0A is connected to expansion I/O module 1A, with a chain of
connections cascading down (blue). Controller I/O module 0B is connected to the lower expansion I/O
module (7B), of the last drive expansion chassis, with connections moving in the opposite direction (green).
