# SAN's are not magic, they fail when their components get old or their environment changes. The failure may lack grace.
SAN's are built up from storage arrays and every component in a storage array can fail and often in multiple diferent ways. Redundant components are included typically but every different component has a set of inherent weaknesses.
Not to miss mentioning software problems/bug and human error/mistakes/ deliberate hacks. Received on Mon May 02 2011 - 13:40:01 CDT
