Fault Tolerance with Multiple NICs

Apologize if this has been asked before.

I am setting up a vSphere 5.5 environment and I have enough 1GB NICs per host to dedicate two NICs per host for Fault Tolerance.  I was wondering the best way to set this up for maximum network throughput.  Do I set it up like Multi-NIC Vmotion?  Like stated here: VMware KB: Multiple-NIC vMotion in vSphere 5. Basically using two Port Groups like FT-1 and FT-2.  Or do I have to do it like Multi-NIC iSCSI with separate vswitches and each vswitch with a one of the Port Groups.

Thanks in advance.
