Sql-server – sql server NUMA binding to ports

I am trying to allocate a set of CPUs on a 2 node NUMA server as below :

Below is from coreinfo that shows physical processors, logical processors and NUMA nodes on the server.

Logical to Physical Processor Map:
**--------------  Physical Processor 0 (Hyperthreaded)
--**------------  Physical Processor 1 (Hyperthreaded)
----**----------  Physical Processor 2 (Hyperthreaded)
------**--------  Physical Processor 3 (Hyperthreaded)
--------**------  Physical Processor 4 (Hyperthreaded)
----------**----  Physical Processor 5 (Hyperthreaded)
------------**--  Physical Processor 6 (Hyperthreaded)
--------------**  Physical Processor 7 (Hyperthreaded)

Logical Processor to Socket Map:
********--------  Socket 0
--------********  Socket 1

Logical Processor to NUMA Node Map:
********--------  NUMA Node 0
--------********  NUMA Node 1

I am running 2 instances of sql server 2008R2 Standard Edition.

What I have done is :

Bind NODE 0 to Instance 1. So instance1 will have 8 logical processors.

ALTER SERVER CONFIGURATION SET PROCESS AFFINITY NUMANODE = 0
GO

2013-11-07 13:01:20.79 Server      Processor affinity turned on: node 0, processor mask 0x00000000000000ff. Threads will execute on CPUs per affinity settings. This is an informational message; no user action is required.
2013-11-07 13:01:20.79 Server      Processor affinity turned on: node 1, processor mask 0x0000000000000000. Threads will execute on CPUs per affinity settings. This is an informational message; no user action is required.
2013-11-07 13:01:20.82 Server      Using dynamic lock allocation.  Initial allocation of 2500 Lock blocks and 5000 Lock Owner blocks per node.  This is an informational message only.  No user action is required.

2013-11-07 13:01:20.83 Server      Node configuration: node 0: CPU mask: 0x00000000000000ff:0 Active CPU mask: 0x00000000000000ff:0. This message provides a description of the NUMA configuration for this computer. This is an informational message only. No user action is required.
2013-11-07 13:01:20.83 Server      Node configuration: node 1: CPU mask: 0x000000000000ff00:0 Active CPU mask: 0x0000000000000000:0. This message provides a description of the NUMA configuration for this computer. This is an informational message only. No user action is required.

I can see instance 1 able to listen on NODE 0 as below :

2013-11-07 13:01:21.05 Server SQL Server Network Interfaces initialized listeners on node 0 of a multi-node (NUMA) server configuration with node affinity mask 0x0000000000000001. This is an informational message only. No user action is required.

NOW ON INSTANCE2 :

Bind NODE 1 to instance 2. So instance2 will have 8 logical processors.

ALTER SERVER CONFIGURATION SET PROCESS AFFINITY NUMANODE = 1
GO

The error log confirms this as well :

2013-11-07 13:03:51.16 Server      Detected 16 CPUs. This is an informational message; no user action is required.
2013-11-07 13:03:51.49 Server      Processor affinity turned on: node 0, processor mask 0x000000000000ff00. Threads will execute on CPUs per affinity settings. This is an informational message; no user action is required.

But why is INSTANCE2 listening on NUMA 0 and NOT NUMA 1 ?

Both instances will have MAXDOP set to 4.

2013-11-07 13:03:51.78 Server SQL Server Network Interfaces initialized listeners on node 0 of a multi-node (NUMA) server configuration with node affinity mask 0x0000000000000001. This is an informational message only. No user action is required.

Also, below are my TCP/IP SETTINGS :

Note:

I have tried below things as well:

1. turn off CPU affinity first and then bind the ports to see if it works. This works Fine, and I am able to see NUMA 0 listening on one port and NUMA 1 listening on second port. This is what I want, but I dont want to turn off CPU Affinity. Am I in the right direction ?

2. CPU Affinity ON. Try NUMA assigning to ports. This does not work in the sense that Instance1 is bind to NUMA 0 and Instance 2 does not show in error log that it is listening on NUMA 1.

Thanks !
