It also tends *over time* to redistribute load more evenly over the physical 
disk farms -- assuming that you have a sufficiently large number of volumes and 
disk subsystems so that you're not totally oversubscribed at the start and you 
have groups/pools defined with disk in different subsystems. There's some risk 
management benefit too; data gets moved around to different places, which can 
reduce the impact of a failure. 

DIRMAINTs disk allocation algorithm works pretty well, albeit these days we're 
typically talking about full volumes so there's not that much placement 
optimization going on at a micro level.
