Interestingly you could go back to Oracle support and ask them about the "SAME" method (as presented by an Oracle employee if I recall correctly at a user conference) - which advocated 1m stripes.
You'll tend to face these battles with EMC - their sales people are great at things like "you don't need to worry about where things are on the disk, or striping etc - our cache takes care of all of that"...Yeah right! As a general guideline, I think you'd be better of with smaller stripe size, but you don't have to limit yourself - you could have fine granined striping for some parts of the system, and larger grains for other parts. hth connor --- [EMAIL PROTECTED] wrote: > Hi, > > Application : OLTP > Environment : Solaris 2.6 on a E10K > Database : 8.0.5.2.1 > > We recently migrated from sun a5200 storage to EMC > symetrix, and we have > been seeing occasional performance problems.
