vNIC Placement Policy for VMWare

I'm setting up a new UCS system to run ESXi 5.0 and would like to set up the service profile so that the vNICs get placed in a particular order. I've looked at the vNIC/vHBA placement policy and I think that between this and the service profile this is where I want to configure the required placement. What I'm not sure of is how to configure the placement policy for optimal efficiency.

I have a VIC 1280 card in each B230 M2 blade. I have 12 vNICs (6 on Fabric A and 6 on Fabric B) that I'm creating for the various networks (Prod, DMZ, Management, vMotion, etc...) on each server. When I look at my current vNIC placement on one of the ESXi hosts where I let the system place the vNICs it looks like they are all on vCon1.

Shouldn't my vNICs be split across the vCons? If so how should I split them? Any best practices or suggestions on how I should configure my placement?

Thanks.

This question has been answered pretty heavily here on CSC and on other blogs - so I wont go into great detail. 

In short:

vCon's refer to Adapters.  One adapter (1280) = 1 vCon.

PCI ordering is managed within the vCon by vNIC/vHBA placement Policy.
