Basically it does a round-robin allocation (+ disk (LUN) size
acquiring). It tries to avoid the hot spots by striping extents across
different disks. But it can't say "uh-huh, we got a hot spot here
let's try to move those things here and there".

My understanding is that ASM will also shift data around to avoid the
"hot block" scenario, avoiding I/O contention. It wasn't explicitly
stated in the passage I pasted, hopefully my understanding is correct.
