I’ve been using CDM for a long time. I like giving it to SAN guys because the disparity between LUNS is often easy to see. You show most SAN guys 30 sql files with different latencies and it won’t mean much. Ask them to explain why the seqs are 450 on one LUN and 280 on another and you get their attention.
