You got it, Steve! PSP on vSphere is very much like PowerPath on MS Windows MPIO. But you can run a third-party MPIO DSM on any version of Windows Server, while VMware makes you buy Enterprise Plus to get any PSP support…

PowerPath/VE is very similar to MS MPIO framework. The default MPIO setup for Windows will allow for path failover, but won't do true DMP or even select the controller that owns the LUN. In essence it's a fail over setup. You can purchase PowerPath, which is just a DSM plugin for the Windows MPIO framework on 2008 (HDLM is also a DSM for MPIO on 2008).
