Is there a way to check whether node interleaving is enabled from within Windows on a Dell R710? omreport chassis biossetup doesn't appear to print any NUMA-related settings on the server I'm looking at.

  • Install Dell OpenManage Server Administrator on the server? – joeqwerty Jan 24 '13 at 14:33
  • I don't see it mentioned in OpenManage either, but maybe I overlooked something. – James L Jan 24 '13 at 15:13

I saw this old question today and remembered that I had overlooked it in the output of omreport chassis biossetup. The setting is named, unsurprisingly, Node Interleaving. However, in omconfig, it's named NUMA. These terms can get rather confusing when changing the setting.

Disable node interleaving (enable NUMA):

omconfig chassis biossetup attribute=numa setting=disabled

Enable node interleaving (disable NUMA and change back to an SMP-like UMA mode):

omconfig chassis biossetup attribute=numa setting=enabled

If this sounds odd, then you probably read it correctly. Yes, you set attribute=numa to disabled to turn on NUMA.
