thick provision lazy zeroed

Thick provision lazy zeroed is a provisioning format for a virtual machine (VM) disk that creates a virtual disk in a default thick format.

Thick provision means all the space designated for the virtual disk files is reserved when the VM is created. Lazy zero means that blocks containing older data on the storage device are only cleared when the virtual machine writes new data to the disk for the first time.
