Hi,
we have a Windows 2008 R2 server with 96 GB of RAM, running SQL Server 2008 R2 on it. We have 4 instance, whose memory maximums are (in GB) : 4, 16, 16, 32. Total : 68 GB. My question is : can I create another instance of 16 GB without putting in risk the Windows 2008 R2 server performance?
I can put the question in another more generalistic way : what is the minimum amount of RAM we should leave free (without assigning to any SQL instance) in a SQL 2008 R2 server? Keeping in mind the O.S. is Windows 2008 R2
Hope the question is clear, and that anybody could help us
Best regards,
