Ok I'm starting to get a better understanding of what you are trying to say. Terminology is a bit off but thats OK!

The third server "server C" which you setup as an ESXi host will not perform the actions of providing shared storage.

VMware doesn't do the shared storage portion, a seperate mechanism must do that which would be a SAN in 99.9% of setups.

It sounds to me like you don't have a SAN, hence the discussion about FreeNAS.

So in your setup you would need to do the following:

Setup server "C" with whatever OS runs FreeNAS (I'm not familiar with FreeNAS). Setup and configure FreeNAS to create and share out a LUN (or whatever FreeNAS may call it) to both servers "A" and "B", both servers A & B must have access to this same storage location.

Then, assuming this is configured correctly, you can go into vCenter and attach that storage LUN to both servers A & B. Essentially a shared datastore.

This will meet the shared storage requirement for vMotion. The only other portion to setup would be the network configuration for vMotion from within vCenter.
