I'm looking at PLE (Page Life Expectancy) across NUMA nodes on our SQL Servers, and came across a rather weird distribution. NUMA node 000 has a very low PLE compared to 001. I'm unsure why this is. I've checked on multiple other SQL Servers in our environment, and the other production servers do not have this behavior.
System is running SQL Server 2012 Enterprise Edition on Dell m620 with 256GB Ram. It's a 2 socket, 6 core (HT enabled) machine. MAXDOP is set at 6. AFAIK memory modules are installed evenly across the memory banks of the CPUs
Something tells me NUMA node 000 has other SQL tasks to perform, that other nodes, but i've forgotten where I heard/saw it.
@@Version shows: Microsoft SQL Server 2012 (SP1) - 11.0.3412.0 (X64)
