I have a SQL 2012 VM that is running 40 GBs of RAM and 6 instances. As I understand I need to set the max of each to where the sum of all of them is lower than 40 GBs of RAM. My only confusion is the minimum. The article below says the minimum should have a sum slightly lower than the total what my total physical memory is.. That doesn't make sense to me. Can someone elaborate on this?
