Symantec Endpoint Protection for Windows Server 2012 with Hyper-V

Hi,

We're planning to do a setup of 12 servers, 6 of the servers are physical and 6 are virtual machines of Hyper-V.  Which of the Symantec Endpoint Protection is suitable for us?  Symantec Endpoint Protection or Symantec Endpoint Protection Small Business Edition?  The way we understand the features of the regular one, we only need to buy 6 licenses for the 6 physical servers and the virtual machines running inside will be protected also while the Small Business Edition, we need to purchase one for each servers which is 12.  Can you confirm this, thanks.
