 can you tell me how having a separate instance specifically for ASM in addition to your production instances is considered less moving parts? As far as code path, raw versus direct IO CFS comparisons are old school. ASM has, um, quite a bit of overhead and comms when manipulating files (not to be confused with manipulating the contents of files).
