Lun Disk Passthrough disadvantages

[Nicolai]

What are the disadvantages to LUN Disk Passthrough ?

I know that the VM will not see SMART values, but what other disadvantages does this have ?

Could I just remove the drive and plug it into another Pc and it will just read the files fine ?

If I format the drive in the VM, will it keep the formatting on the Drive ?

In Essence: is the Drive passed through 1:1, or is there some sort of abstraction layer that prevents me from just unplugging the Drive and using it on another Pc like any other drive ?

That depends on the passthrough method. If you passthrough your HBA, you will be able to see them.

What are the disadvantages to LUN Disk Passthrough ?

No snapshot functionality, redundancy has to be part of the guest OS.

Could I just remove the drive and plug it into another Pc and it will just read the files fine ?

Yes, as with every other disk (depends on filesystem, redundancy and other intrinsic things, but identical to every other usb disk).

If I format the drive in the VM, will it keep the formatting on the Drive ?

Yes.

In Essence: is the Drive passed through 1:1

that is what passthrough means.
