Path Selection Plug-Ins and Policies
VMware Path Selection Plug-ins (PSPs) are responsible for selecting a physical path for I/O requests.
The plug-ins are submodules of the VMware NMP. The NMP assigns a default PSP for each logical
device based on the device type. You can override the default PSP.
