Adam is right, you should first decide on which protocol to use since there are differences on multipath configurations depending on the protocol you choose.
For iSCSI on Windows, take a look at this: https://communities.netapp.com/blogs/mikemcnamara/2011/06/06/demartek-iscsi-deployment-guide-2011
For VMware, also take a look at this: http://www.netapp.com/us/media/tr-3749.pdf
* there are amenities that should be considered depending on the protocol you use.
Hope this helps.
