Despite vendors' efforts to simplify SAN implementation and management, they remain difficult to build, maintain and manage. Surprisingly, there are only a couple of SAN design tools that help storage administrators to design and update a SAN over time. The need for SAN design automation is clear. "As soon as you go beyond a SAN that is small--maybe one switch and a few devices--you can't design it with paper and pencil, a spreadsheet or a whiteboard," says Bill North, director of research, storage software at International Data Corp. (IDC). "Everything just breaks down." For most organizations, expanding a SAN is a trial-and-error process.
