Hi,

I have a VMAX 250FX running PowerMax OS with Unisphere 9 and SE 9.  I have noticed the compression ratio is different among the GUI, and CLI so I get confused which ratio should be used.

1. The GUI show data reduction of 2.8:1

2. symcfg list -srp -efficiency show 2.6:1

3. symcfg list -pool report compression ratio of 2.2:1

If I want to calculate capacity saving before and after apply compression, which output I should rely on.
