So having read up on automatic soft-NUMA, I was eager to see what it did with my main production servers when I upgraded them. My main pair of production servers (they are paired into an Availability Group) have 4 NUMA nodes with 16 physical cores per node and hyperthreading for a total of 32 logical cores per node with 1.5 TB of RAM. Obviously, we are using core-based Enterprise Edition for these servers. I thought I knew what automatic soft-NUMA would do, and wanted to confirm if my expectations were right.
Read on, but it looks like there’s a “to be continued…” here.
