Multipath I/O (MPIO)

Microsoft Multipath I/O (MPIO) is a framework provided by Microsoft, which enables storage providers to

develop multipath solutions that contain the hardware-specific information. It is required to optimize

connectivity with their storage arrays. These modules are called

Device-Specific Modules (DSMs). MPIO

is protocol-independent and can be used with Fibre Channel, Internet SCSI (iSCSI), and Serial Attached

SCSI (SAS) interfaces in Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, and

Windows Server 2012 R2.

MPIO provides the following features:

• High application availability through failover clustering

• High availability for storage arrays

• SAS disk compatibility

• The ability to perform MPIO tasks through Windows PowerShell cmdlets

NOTE: To work with the DSM provided by Microsoft, storage must be SCSI Primary Commands-3

(SPC-3) compliant.

Managing Devices On MPIO

To manage devices on MPIO:

1. In the Server Manager menu bar, click Tools → MPIO .

The MPIO Properties window is displayed.

2. On the MPIO Devices tab, click Add and enter the Device hardware ID of the device you want to add

MPIO support for and click OK.

3. The device hardware ID's are seen in the Discover Multi-Paths tab.

NOTE: A device hardware ID is a combination of vendor’s name and a product string that

matches the device ID that is maintained by MPIO in its supported device list. The vendor and

product IDs are provided by the storage provider, and they are specific to each type of

hardware.

4. On the DSM Install tab, enter the DSM INF file and click Install or Uninstall to install/Uninstall a DSM.

5. On the Configuration Snapshot tab, capture the snapshot of the current MPIO configuration on the

system, specify a filename for the information to be captured and click

Capture.
