What's the different between "Snapshot Space （GB）" and "Current Size (GB)"

[wilber8222]

I noticed the value of "Disk Space|Snapshot Space (GB)" and "Disk Space Reclaimable|Snapshot Space|Current Size (GB)" are different.

Looks like "Disk Space|Snapshot Space (GB)" is like actual use from vSphere Client and PowerCLI.

Does anybody know why "Disk Space Reclaimable|Snapshot Space|Current Size (GB)" is bigger value?
