Description Sandra McCann 2017-12-01 16:29:52 UTC
Add content to the NFV Configuration guide to specify that each NUMA socket needs at least one PDM thread assigned to it.

Comment 3 Sandra McCann 2017-12-15 16:25:15 UTC
In the following section in the NFV Planning and Prerequisite Guide:

The NUMA and NIC details between the introspection example and the manual retrival example are using different topologies. These two sections should use the same underlying hardware to ensure the information is compatible/understandable between the two approaches.

Comment 5 Sandra McCann 2017-12-15 16:40:04 UTC
In the following section in the NFV Planning and Prerequisite Guide:

The image shows PMD threads on each NUMA node, but the content does not clarify or highlight this requirement.  Add content to clearly point this out.

Comment 6 Sandra McCann 2017-12-18 18:49:25 UTC
In the following section in the NFV Planning and Prerequisite Guide:

Section already talks about needing one PMD thread pair per NUMA node, but turn this into a highlighted NOTE to improve visibility.

Comment 8 Sandra McCann 2017-12-18 19:52:03 UTC
In the NFV Config guide, add a note to each section on network_environment.yaml to clarify the need for PMD threads on each NUMA node.
