High availability features

Two interconnected controllers ensure that the failure of a controller component does not disable the
system. A single controller can fully support an entire system until the defective controller, or controller
component, is repaired. For EVA8x00 configurations with more than four disk drive enclosures, the
complete data redundancy configuration includes device loop switches on the two Loop A and two
Loop B data paths. For EVA4x00 and EVA6x00 configurations, data redundancy is accomplished
with device loop switches on the two Loop A data paths.
