Although all SCSI devices are presented as SCSI targets, what are the three physical implementation alternatives:

A.
Device mapping locally

B.
Virtual machine .vmdk file stored on a VMFS volume

C.
Local SCSI device passed through directly to the virtual machine

D.
Device mapping to a SAN LUN

Explanation:

1.) Virtual machine .vmdk file stored on a VMFS volume. See .Virtual Machine File System (VMFS).
2.) Device mapping to a SAN LUN (logical unit number). See .Raw Device Mapping.
3.) Local SCSI device passed through directly to the virtual machine (for example, a local tape drive).
