Install or Uninstall a DSM
Applies To: Windows Server 2008 R2
Many storage arrays that are active-active and SPC-3 compliant will work using the Microsoft Multipath I/O (MPIO) Device Specific Module (DSM). Some storage array partners also provide their own DSMs to use with the Microsoft MPIO architecture. When installing a non-Microsoft DSM, if that DSM does not have its own setup package, you can install compliant non-Microsoft DSMs by browsing for the DSM’s .inf file, and then clicking Install. You can also uninstall a non-Microsoft DSM by clicking Uninstall.
