If you want to use FT then you will need 6 uplinks. If you are happy to drop FT off then you can use 4 uplinks. The configuration would be;
vSwitch0 - Management
Management - vmnic0 active / vmnic3 standby
vMotion - vmnic0 standby / vmnic3 active
vSwitch1 - VM Networking
VM - vmnic1 active / vmnic2 active
Where vmnic0,1 are using inbuilt NIC ports and vmnic2,3 are using mezz NIC ports.
You could put all uplinks and networks on a single vSwitch but in my experience this makes maintenance harder and more complex. Also you need more complex active/standby NIC configurations.
