Installing VMware on a new Dell server with 2 Intel Xeon E5-2630v2 2.6GHz, 15M Cache, 7.2GT/s QPI, Turbo, HT, 6C, 80W, Max Mem 1600MHz.  Intel says each processor has 6 cores

When I am creating a VM using my VMware Workstaion is asks how many processors and how many cores per processor.  I am a little confused by what I should set this up as.  My long term goal is to run 2 virtual 2012 Standard servers on this new Dell server and have enough resources to spin up a third VM as a backup to another physical 2012 server.

this is what I currently have from VMware
