Thank you, John, for the clarification. I am even more curious now how the feature limitation of the storage management functionality would be enforced? If I take WinServer 2012 Standard and enable iSCSI target and surrounding functions then I probably will have unlimited number of hard drives supported etc. and if the same storage management function (iSCSI target) gets enabled on a Foundation server or Essentials then I will not be able to access more than 6 drives, set up dedupe and clustering? Windows Storage Server 2012 however can't act as the domain controller and obviously generic Win Server 2012 Standard can. What edition of Windows Server 2012 is then lying under each edition of Storage Server?
