Thick provisioning: This approach can instantly allocate physical storage space
for the volume. Physical space will be created as soon as the space is allocated
for the volume, and that space cannot be used by other volumes.
A thick provisioned volume is usually more efficient for high frequency read/write
activities. Because the space has been allocated for the volume, the
predicament of insufficient physical space can be avoided, but the use of space
is relatively inefficient.
