You can view how datastore storage space is allocated for your virtual machines.

Storage Usage shows how much datastore space is occupied by virtual machine files, including configuration and log files, snapshots, virtual disks, and so on. When the virtual machine is running, the used storage space also includes swap files.

For virtual machines with thin disks, the actual storage usage value might be less than the size of the virtual disk.


Browse to the virtual machine.


Select a datacenter, folder, cluster, resource pool, or host.


Click the Related Objects tab and click Virtual Machines.


Double-click the virtual machine and click the Summary tab.


Review the storage usage information in the upper right area of the Summary tab.
