What do you mean 'targeted load testing'? If we mean the same thing, ASM appears to [attempt to] rewrite the rules of any load testing that I can envision - potentially obsoleting the conventional disk management wisdom. However, at the same time ASM monitors load, provides reports on load by disk, and automatically attempts to rebalance load according to need. /HansF (using my gmail account in this hotel)
