My company intend to buy a new server and will dedicate that for SQL Server which will serve an in-house developed application.
How can we know how many processors are enough to buy?
I know that each SQL Server edition and version has it's different limitation of the number of processors it can support, for example SQL Server 2012 Standard Edition can support up to 4 sockets or 16 cores per SQL Server Instance, but this does not mean that I have to buy 4 physical CPUs. two could be enough. how can I know?
