ASM manages disks partition and maintains its own structures for allocations, multiplexing, extensions and alike. That puts it into the category of volume managers. Now, there are several questions to ask:

1. Do you need a volume manager and, if you do, what for? Do you already have one? Is it adequate?
2. What are the alternatives? Which volume managers are available that fit your needs.
3. What criteria will you use to make a selection? Price? Performance? Compatibility with the rest of your software?

Unfortunately, I cannot answer those questions for you.
