I have a growing SAN and so time has come to start considering a better
approach to managing it. Being a person with tons of experience with Sun
stuff, I'm interested in ESM AA and the demo of it on Sun's website
seems to indicate it has what I'm looking for.

Has anyone here used or currently uses it to manage their SAN? Any
thoughts? Is it broken into modules that you purchase piecemeal or is
ESM AA a complete suite of tools?

TIA,
