Turned on AO today for the first time.
Really surprised at what it moved around between cpg/tiers.
Data that I would have expected to be low I/O moved up tiers, and vice-versa for data that I would have considered higher I/O moved down. Good to see it is idenitfying the hot/cold regions and moving accordingly. Really like the CPG space view under Virtual Volumes so you can see how the volume has been spread out over the CPG/tiers.
