Bare Metal Server Configuration

This is a companion thread to my other thread about general performance tuning of Acumatica. However, this is specific to hardware configuration for bare metal servers running Acumatica. I am probably going to separate the application and database servers. So any suggestions for bare metal SQL Server and bare metal IIS for Acumatica? I may run some thin virtualization layer in order to run many instances, but the goal is to give the instances as much access to server horsepower as possible. Any suggestions from the field? Assume money is not an object.
