I have a recommendation that striping has little effect because "the server I/Os are random and read / writes occur in small increments (4-6Kb I/Os)."
This was an ADSM and not a TSM recomendation. Personally I hate striping as it's so hard to manage the disks when you want to move stuff around.

November 2001 16:16 An: [EMAIL PROTECTED] Betreff: Best Database Performance Does anyone have a feeling about what is best for database performance? I have, since we moved to AIX, taken the 4 physical drives (actually 8 with ADSM mirroring), and striped it into one large volume. I saw a post the other day that suggested that maybe splitting it to 4 individual volumes might be better, as ADSM can schedule across these volumes. What I am seeing leads me to believe that ADSM is hitting one volume, and it's mirror predominately. Was I better off striped? Any suggestions? Thanks for any info.
