The drive by IT organizations toward efficiency in capital equipment and human resource utilization is highlighted by the server and storage consolidations, which is pushing the conversion from
direct attached storage (DAS) to network attached storage (NAS) and storage area networks (SAN).
The shift from parallel technology to the emergence of new serial based architectures as new I/O standards for
direct attached storage changes the traditional cost/benefit equation, and the addition of powerful, yet cost-effective RAID capabilities alters the landscape for low-cost server storage.
