If the connection between an Out port on the controller and an In port on an
enclosure fails, an alternate path exists through the second Out port on the
controller and the second In port on the enclosure. For more information, see
Figure 4-11, Figure 4-12 and Figure 4-13.
NOTE:
The PERC 6/E adapter supports redundant paths when used with
