The default for data progression to start running is at 7:00 PM, but yes its decisions are based off of replays and the storage profiles you configure. If you're keeping backups on the Compellent you should look into moving that LUN onto a storage profile at a very low tier (RAID5 on SATA) otherwise the SAN will just see some blocks churning and punt them up to expensive disks once the magic threshold is reached. If you mean that you have, say, 1.5 TB of virtual machines that you think is getting moved up, that sounds like a different issue to me. I just checked the little book that came with the "Compellent Certified Storage Administrator" course and there's no reference to how to see which volumes have blocks that will be migrated, and I don't see anything in my 5.0.4 storage center GUI. Probably need to call Copilot to find out what the deal is.
Hi, I'm wondering about the value I'm seeing in the middle of the day for data pending moving up within tier 1. Correct me if I'm wrong, but the data progression cycle is the replay schedule?  It's 6 pm for us. I have 1.5 TB waiting to move up.  Where can I learn more about that data to know if it should be moving up.  There's still debate amongst my team whether the backup schedule is confusing the calculation and making it work for nothing. If 1.5 TB wants to move up and the data progression starts at 6 pm, then 1.5 TB was changed after hours, causing speculation that the backups are causing all of this. Thanks, rudif
1.5 TB wants to move up the next data progression cycle
