From what I hear, automatic tiering is the direction a lot of people are going/have gone. I recently applied the hotfix and got the "storage tiers" page working and populated. However, the information is just a duplicate of what you have setup in the array. (# of disks, # of luns per tier) and not something I would ever need to look at. In fact, I can't see this being useful to anyone. I know not all auto-tiering works the same for all vendors, but EMC moves it around in 1gb chunks, so the # of luns per disk type is really useles because a lun can sit on ALL tiers. I was hoping to have some sort of reporting on what data was moved where. (10gb moved up from Tier 2 to Tier 1 over the last day) Or iops per tier... There are dozens of other reports that would be helpful. Or a monthly historical report on how much data was moved each night. I'm sure commenters will have more ideas to add. Anything more than what is there would be extremely helpful.
