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. More information can be found
