In case you weren't sure, a storage area network, or SAN, is a collection of computers and storage devices connected over a high-speed optical network and dedicated to the task of storing and protecting data. SANs solve many of the data storage and management problems that have long bedeviled enterprise networks, and they save companies who use them a bundle. Which is why SAN administration is one of the highest-paid jobs in IT today. Add storage area networking to your resume and your phone will ring off the hook with calls by head-hunters promising of six-figure salaries.

The second edition of Storage Area Networks For Dummies covers the hot, new technologies that are revolutionizing SANs today, including Fibre Channel over Ethernet (FOE), iScsi, and data de-duplication.
