File Type Description
Snapshots Amount of disk space used by virtual machine snapshot files.
Snapshot files store information about virtual machine snapshots. They include snapshot state
files and delta disk files. A snapshot state file stores the running state of the virtual machine at the
time of the snapshot. It has the extension .vmsn. A delta disk file stores the updates made by the
virtual machine to the virtual disks after a snapshot is taken.

Other Amount of disk space used by all other non-virtual machine files, such as documentation files and
backup files.
Free Space Amount of disk space not currently in use.
Total Space Amount of disk space available to the datastore. This is the datastore capacity. The chart displays
the information for datastores but not for data centers.
total space = virtual disk space + swap file space + snapshot space + other VM file space + other
space + free space
Chart Analysis
The datastore is at full capacity when the used space is equal to the capacity. Allocated space can be larger
than datastore capacity, for example, when you have snapshots and thin-provisioned disks. You can
provision more space to the datastore if possible, or you can add disks to the datastore or use shared
datastores.
If snapshot files are consuming a lot of datastore space, consider consolidating them to the virtual disk when
they are no longer needed. Consolidating the snapshots deletes the redo log files and removes the snapshots
from the vSphere Web Client user interface. For information about consolidating the data center, see the
vSphere documentation.
Datastores
The datastore charts contain information about disk usage for datastores. The help topic for each chart
contains information about the data counters displayed in that chart. The counters available are determined
by the collection level set for vCenter Server.
Space in GB
The Space in GB chart displays space usage data counters for datastores.
This chart is located in the Space view of the datastore Performance tab.
