Dynamic Multipathing

In Storage Foundation for Windows, the Dynamic Multipathing option adds fault tolerance to disk storage by making use of multiple paths between a computer and individual disks in an attached disk storage system. Disk transfers that would have failed because of a path failure are automatically rerouted to an alternate path. Dynamic Multipathing also improves performance by allowing load balancing between the multiple paths.

Two forms of Dynamic Multipathing are available, DMP and MPIO. DMP is designed for a multipath disk storage environment that provides Windows mini-port or SCSI port driver support. MPIO is designed to support a multipath disk storage environment set up with the Microsoft multipath input/output (Microsoft MPIO) solution. MPIO works effectively with Windows to provide a fault tolerant multipath disk storage environment. MPIO provides Windows Storport driver support.
