How does the buffer pool handle low memory conditions?

(Thanks to Erik Darling for reviewing this post. Check out his training materials.) One of the bigger clichés in the data professional vocabulary (behind “it depends”) is that you always give SQL Server as much RAM as you can afford, because it’s going to use it. But what happens when SQL Server runs out of

When the buffer pool isn’t just in memory

Last time we looked at the four major components of a computer system, and then looked at the SQL Server buffer pool as a way to leverage the best performance from computing hardware. Temperature Before we dive deeper into the buffer pool, I wanted to briefly mention data access terminology. A common metaphor for accessing

How does the buffer pool work?

Today we’ll begin taking a look at the buffer pool in SQL Server and how it’s normally used. Before we dive too deeply into the buffer pool, we need to remind ourselves of a few fundamentals of how computers process and store information, as that relates to how the buffer pool operates. A computer is

What you need to know about memory limits on SQL Server

Last week, I posted this statement on Twitter, along with a screen capture of the official Microsoft documentation: Reminder: Max Server Memory is *not* just for the buffer pool. The RAM limit Standard Edition can use *is* just for the buffer pool. Joey D’Antoni was quick to remind me that this only applies to SQL
