Wow, I just watched Jeffrey Steiner's presentation "BRK-1151-2 Data Performance: What do you really need?" While attending the Virtual Insight conference. What an amazingly useful talk, I wish it *was* a two hour course, I'd take it again in a hearbeat.
My Netapp setup isn't nearly as upto date as I'd like, and my Oracle DBA does a pretty good job of keeping things humming, but this talk was just really excellent.
If you have a chance, go attend this conference and watch this presentation.
