Answer and Explanation:
RDM has two modes as physical and virtual and depends on the virtualization such as Physical RDM and Virtual DRM Physical RDM expose the SCSI device with the VM and get virtualized as SCSI command go direct the OS. VM takes the lower-level features of the SCSI device. Physical RDM has the following scenarios as Run the management agents Cost-effective to physical clustering Virtual RDM underlying the physical properties and appear as same as Disk file on VMFS volume. The device appears as virtualization and reads and writes the raw LUN. RDM includes the OS file locking and user-friendly names. RDMs with the attacked device and redundant of the independent disk. RDM uses a serial number to identify the SCSI device. SAN has compatibility mode and manages the storage and mirroring operations. Virtualization is a tool that can minimize administrative overhead while increasing scalability and cost. RDM provides the benefits which should be used in every situation. Virtual disk files are preferable to RDMs and provide a user-friendly name for the mapped device.
