What is a SAN? A storage area network (SAN) is a high-speed special-purpose network What is a SAN? A storage area network (SAN) is a high-speed special-purpose network (or sub-network) that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users.

What problems can be solved with a SAN? n Customer requirements n n n What problems can be solved with a SAN? n Customer requirements n n n n Need more performance Need to control exploding storage Caught in the “MORE” trap - more servers instead of more storage Want better disk utilization Want to centrally manage storage Want server/storage consolidation Have shrinking backup windows Want to reduce the risk of downtime 99% Full 50% Full 1% Full
