Sep 25, 2016 · Thick provision lazy zeroed :-Thick provision laze zeroed when used it allocates all the space from the datastore to the vm at time of creation only. VMware vStorage Thin Provisioning lets you subscribe more capacity to virtual machines than they actually have, eliminating the waste of resources and space caused by unused over-allocated storage. It also simplifies storage management by allowing systems to grow their storage requirements without having to micro-manage capacity allocation. You must be running a thin disk. Linear storage take advantage of the advanced virtualization features of the firmware. Because the default virtual machine storage policy is compatible with any vSAN datastore in the vCenter Server, you can move your virtual machine objects provisioned with the default policy to any vSAN datastore in the vCenter Server.
