Why each option
To over-allocate storage on virtual machines in a development cluster, the practice of thin provisioning is used.
LUN masking is a security feature used to restrict access to a LUN from unauthorized servers, not for storage allocation.
Thin provisioning allocates only the storage space actually written to disk, while presenting a larger, virtually provisioned size to the virtual machine. This allows the total virtual disk capacity assigned to VMs to exceed the physical storage capacity, enabling over-allocation.
Thick provisioning pre-allocates and reserves the entire specified storage capacity on the physical array when the virtual disk is created, preventing over-allocation.
FC zoning is a Fibre Channel SAN configuration that controls device communication and visibility within the SAN, unrelated to storage allocation practices.
