BL460c G6 Westmere with RedHat OS RHEL 5.4 or 5.5

Andrew had a question about support for the new higher speed Intel Westmere processors on RedHat OS:



Hello experts,

Please advise for Intel X5670 which is the version of rhel that will have the processor enhancement and numa support it.

5.4 or 5.5?



Daniel provided an answer and a question:



RHEL 5.4 supports X5670, including NUMA.   I’m not sure if NUMA is enabled by default.


By “processor enhancement” do you mean the new AES-NI instructions?
