Microsoft MPIO support allows the initiator to log in to multiple sessions to the same target and aggregate the duplicate devices into a single device exposed to Windows. Each session to the target can be established using different NICs, network infrastructure, and target ports. If one session fails, another session can continue processing I/O without interruption to the application. The iSCSI target must support multiple sessions to the same target. The Microsoft iSCSI MPIO DSM supports a set of load balance policies that determine how I/O is allocated among the different sessions. With Microsoft MPIO, the load balance policies apply to each LUN individually. The Microsoft iSCSI DSM v2.x assumes that all targets are active/active and can handle I/O on any path at any time. There is no mechanism within the iSCSI protocol to determine whether a target is active/active or active/passive; therefore, the iSCSI or iSCSI/FCoE modules support only multipath configurations with the EVA with active/active support.
