Usable Storage x Raw Storage

Hi,

I found these and views that shows when space I am using and how much I have available.

However, the only view that shows when I actually have it is the latest version of vSAN 6.7.

In previous versions, how do I see this free space that shows in the latest version of vSAN?

Thank you.

vSAN 6.5
