In the screenshot below, you will see our Exchange server storage config. We have a couple disks on it:

Disk 1: 50GB (Drive C - System)
Disk 2: 150GB (Drive E - Exchange DB)
Disk 3: 150GB (Drive F - Exchange DB)
Disk 4: 150GB (Drive G - Public Folders)

 Disk 2 (drive E) is on Napp01_vol1. As you can see the VMDK is thin provisioned for 150GB. Why does the virtual machines tab indicate 200GB of provisioned space for this vm, and 186GB used?

Another option could be (and without seeing where all your HDs are located), you have your Hard Disk 1 (50GB) on the same drive as 1 of your other HDs, thus why you have shown 200GB provisioned. Used would obviously be less than that 1. because you haven't fully utilized the whole allocated space and, 2. some of the storage for the disks take into account the vswp and log files, etc.
