 The Datamover Architecture (DA) defines an abstract model in which the movement of
data between iSCSI end nodes is logically separated from the rest of the iSCSI protocol; iSER
is one Datamover protocol.The interface between the iSCSI and a Datamover protocol, iSER
in this case, is called Datamover Interface (DI).The main difference between the standard iSCSI and iSCSI over iSER is the execution of
SCSI read/write commands.
