Connecting direct attach configurations

MSA 1050 controller enclosures support dual-controller 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 1050 diagrams that follow use a single representation for FC or iSCSI host interface protocols. This is
due to the fact that the port locations and labeling are identical for each of the three possible SFPs supported by the
storage system. Within each host connection cabling category, the HD mini-SAS model is shown beneath the SFP model.
