Hi,
I have read the advice about maxdop and numa but I am still confused if you have hyperthreading. We have an HP DL380 G7 that has 2 sockets with 6 hyperthreaded cores on each that are split into 2 numa groups. So SQL sees 24 cpus. According to KB articles I see that for our OLTP system we should not set maxdop to higher than the number of cores ina numa group. We currently have maxdop set to 8 as this is a recommended setting for OLTP on a server with more than 8 cores. With our situation should this be set to 6 because thats how many hyperthreaded cores we have in each node?
Thanks
Chris
