RDM and iscsi

This is something for educational purpose, hope someone will answer . For an example, I have a VM and it has iscsi initiator . I create a LUN in equallogic and connect this lun using the iscsi initiator by passing the esxi .
Will that be RDM device?

Whether using the Add Drive - RDM or using the iscsi initatior as you have done they are both considered Raw Device Mappings. Whether to use RDM or iSCSI depends on how much you want to manage the storage from within the VM. Using Software iSCSI Initiators within a VM means you need to deal with that when you do upgrades, etc. If you use RDMs you leave the management of such up to vSphere.

It's a RAW LUN connected to the VM, which is not really considered a VMware RDM, which is a LUN passed through to the VM via ESXi.

Hanccocka,
It uses esxi phyisical nic (via vswitch) to connect the LUN using  guest iscsi initiator (microsoft iscsi or netapp or equallogic ).
So it is not either called passthorugh nic or RDM and it called Lun passthorugh to VM, am I correct?
