MSA 1060/2060/2062 controller enclosures support dual-controller configurations only. If a partner controller fails, the
array will fail over and run on a single controller until the redundancy is restored. A controller module must be installed
in each IOM slot to ensure sufficient airflow through the enclosure during operation.
NOTE The MSA 2060/2062 and MSA 1060 diagrams that follow use a single representation for each SFP cabling
example. This is due to the fact that for either the 4-port or 2-port controller module face plates, the port locations are
identical for FC and iSCSI. Within each host connection category, the SAS model appears beneath the FC or iSCSI model.
