SAS connections each. The IOMs are N+1 redundant,
hot-swappable components. The IOMs are installed
into the central bay from the top of the Chassis
and connects to the drive board. The baseboard
completes the connection to the Mini-SAS HD ports,
which extend out the rear of the enclosure. Each
IOM contains a primary and two SAS expander chips,
and an out-of-band management (OOBM) chip that
connects to the management port on the rear of the
