I'm not an ASM expert by any stretch of the imagination, nor do I use it! But I'll write here a little, anyway :-(

There's been lots written and available on the web on this subject. A search "why oracle asm" yielded many articles.

ASM seems give one a level of indirection, pretty much removing the underlying storage complexity and putting storage more in tune with Oracle tools, concepts and syntax.

I'm not at all surprised that your storage administrators don't want it. It's foreign to them and different from everything else they do. Everything about ASM is a complexity to them, I suspect.

Should ASM be a DBA function rather than storage admin function? I don't know, I'm just asking, but unless you have a lot of databases, I can see where your typical storage admin would see ASM as a black hole of time and complexity, whereas the DBA could appreciate its value, albeit a black hole of time and complexity. ;-)

Cheers, Wayne
