Dell Compellent vs VMware -> incorrect free-used space report

Hello ALL

We have Dell Compellent with the latest FW 7.4.10.27, vCenter 6.7.0.44000 and hosts 6.5.0, 15256549.

Finally, we started to use dedulication and compression (yeah, 2020 is outside...) and I've found that SC cannot report VMware the actual free space on volume.

My previous experience was with NetApp FAS and VMware 6.5 and everything worked fine with thin provisioned volumes, VMs and dedup+compress.

Now, back to storage and vmware:

I see "Total Disk Space" in DSM is 5.83TB, but VMware says I have 11TB used on my datastore.

The question is HOW to report the correct free space?
