You are converting your physical servers into virtual machines. One prospective virtual machine
has an application that utilizes a 1.5 TB SAN LUN for data. You are concerned that this new virtual
machine would take too long to convert to a virtual machine. How can you configure the storage of
this virtual machine to minimize the conversion time required to copy the data across the network?
A.
Place the new VM on a thin provisioned VMFS volume with other VMs
B.
Place the new VM on a shared VMFS datastore with other VMs
C.
Place the new VM on local storage available to only one ESXi host
D.
Deploy the new VM with a raw device mapping (RDM)
Explanation:
http://www.vcritical.com/2009/10/responsible-thin-provisioning-in-vmware-vsphere/
Thin provisioned VMFS volume? I know that you can configure a VM storage (VMDK file) to be thin-provisioned and also some storages can create thin-provisioned LUNs on which you can create VMFS volumes, but I did not hear about thin-provisioned VMFS volume. That does not mean they do not exist, it just means I never heard of them.
Anyway, that is not the answer I would choose. I would go for, RDM (answer D), because it would allow me to not copy the 1.5 TB volume at all, instead I would just “mount” it to the new VM.

but hpw can u add a local storage without VMFS format add to a virtual machine as a vmd ?

I agree the correct answer is D: RDM with the following assumption that you would still need to build up a new vm or P2V the OS, that could be a thin provisioned and then configuration application volume as the RDM therefore you would not need to move the large amount of data.

agreed, D- RDM is the answer

Am i the only one confused by this sentence:
“You are concerned that this new virtual machine would take too long to convert to a virtual machine.”
How can you convert a VM to a VM.
You can only convert a Physical to a VM.
