no ASMs are considerably different. Its supposed to manage everything. You dont give 
it a file, you give it entire disks and oracle does everything. Sets up files, 
manages, I/O, everything.

you only look at the tablespace level. you dont even install any software on it. If 
your on SAN, you dont install SAN software on it.
