Multi-Path I/O
Microsoft MPIO is supported with iSCSI Storage Area Networks as well as Fibre Channel and Serial Attached SCSI (SAS) storage. Microsoft includes a Microsoft iSCSI Device Specific Module (DSM) with the Microsoft iSCSI Software Initiator which supports many arrays and allows the creation of multiple paths for failover and load balancing. Storage array vendors can also license the Microsoft MPIO DDK from Microsoft and implement their own DSMs specific allowing their storage to interface to the Microsoft MPIO core driver stack. The Microsoft iSCSI initiator can be installed with Microsoft MPIO, the same MPIO that is available for other types of storage. Multi-path I/O provides the benefits of fail-over if a path fails and load balancing across multiple active paths to increase throughput.
It is important to note that when using multi-path I/O for iSCSI storage solutions, both the iSCSI initiator and the iSCSI target need to support MPIO. Each network adapter and its associated ports in the iSCSI initiator and iSCSI target should have identical features to insure consistent performance. The iSCSI DSM implements several load balance policies designed for different link performance metrics.
