I'm attempting to determine exactly how much space my vCenter Server data is using on my Oracle database. The size of the .dbf file is 120GB. However, as you can see in the diagram not all of the space inside the .dbf file seems to be actual data. I'm tryng to figure out how big the data will actually be if I move vCenter Server to SQL Server so I can size my SQL server. How can I tell what my actual data usage is? Any tips / pointers appreciated.
