Storage Area Networks (SANs)
Storage area networks (SANs) distribute data and other
information to multiple storage devices that are interconnected by data
networks. SANs allow for the sharing of resources and pooling of information in
the form of shared files at both the server level and the client (individual PC)
level. Storage area networks (SAN’s) provide fault-tolerant operation through
the use redundant data storage in multiple locations. If a failure occurs in one
data storage device, other redundant data storage devices may automatically be
used as the backup source of information.
