Reasons *for* ASM that I can see. I agree with most of your negatives :). - Ease of file management - which is mostly OMF rather than ASM per se. (that's a disagreement!) - Ease of disk management - having the ability to migrate a db from one set of physical disks to another witout downtime is very, very cool. - On windows avoiding the whole drive letter management thing. Now against that, and in addition to Jared's points. I'd ask why consider a storage solution that *only* works for Oracle files (and even then not all Oracle files. I keep other files on my servers you know. Including stuff you'd expect to be there like alert.logs, cron scripts and so on.
