As the name indicates, these are physical LUNs or hard drives passed on from the Hyper-V hosts, and can be assigned to a virtual machine as a standard disk. A once popular method on older Hyper-V platforms, this allowed the VM to harness the full potential of the raw device bypassing the Hyper-V host filesystem and also not getting restricted by the 2 TB limit of VHDs. A lot has changed over the years, as Hyper-V has matured into a superior virtualization platform and introduced VHDX, which went past the size limitation. with Windows Server 2012 R2 can be used as a shared storage for Hyper-V guest clusters.

There are, however, demerits to this virtual storage. When you employ a pass-through disk, the virtual machine configuration file is stored separately. Hence, the snapshotting becomes unknown to this setup. You would not be able to utilize the dynamic disk's or differential disk's abilities here too. Another challenge of using this form of virtual storage is that when...
