Description
Use the format of the original virtual disk.
Use the thin format to save storage space. The thin virtual disk starts small
and at first, uses just as much storage space as it needs for its initial
operations. When the virtual disk requires more space, it can grow to its
maximum capacity and occupy the entire datastore space originally
provisioned to it.
Only VMFS datastores version 3 and later support virtual disks in the thin
format.
Allocate a fixed amount of storage space to the virtual disk. The virtual disk
in the thick format does not change its size and from the very beginning
occupies the entire datastore space provisioned to it.
