vspshere storage explanation

Hello community,

I'm trying to understand why provisioned and disk capacity are now equal in vspshere

My provisioned size is 6.39Tb

And hard disk size:

Disk 1: 100GB

Disk 2: 120GB

Disk 3: 850GB

Disk 4: 1.953TB

Disk 5: 500GB

Total: 3.523TB

I have some snapshots, but I can't explain the numbers,

Can you help me to understand delta and flat files? And why the sizes?

Here size details

Do you have read this KB
