Multipathing Plugins (MPPs)
Figure 5.7 depicts the relationship between MPPs, NMP, and PSA.
Figure 5.7. MPPs, including third-party plug-ins
MPPs that are not implemented as SATPs or PSPs can be implemented as MPPs instead. MPPs run side by side with NMP. An example of that is EMC PowerPath/VE. It is certified with vSphere 4.x and is planned for vSphere 5.
