Hi NetApp Community, I am looking for documentation about the underlying technology of NetApp's devices. Meaning when a volume is created how is that placed on the disks and within an aggregate and RAID group. And then when a LUN is created, how is that treated within a volume. Is it spread across a limited number of disks or all of them? I am also looking for information on IOPS. I want to learn the engineering technology about how NetApp does things not just the way to set it up.
