Best design for using 8 physical NICs on an ESXi 5.1 host

I have 8 physical NICs to work with on and ESXi 5.1 host using Enterprise Plus licensing.  I need to service the following traffic:

Management traffic

vMotion traffic

Virtual machine traffic (Probably 2 pnics will suffice for this)

NFS traffic

Fault tolerance will NOT be used.  How many pnics should I dedicate to NFS, vMotion and management traffic?  What failover policy should I use (active / active) (active/standby) for each?

This is enterprise plus licensing and vSphere Distributed Switches are being used.

Thanks
