NumaNode Class

The NumaNode object represents the settings for a NUMA node on an instance of SQL Server.

Inheritance Hierarchy


Namespace:  Microsoft.SqlServer.Management.Smo
Assembly:  Microsoft.SqlServer.Smo (in Microsoft.SqlServer.Smo.dll)


Public NotInheritable Class NumaNode

The NumaNode type exposes the following members.


  Name Description
Public property AffinityMask Gets or sets the affinity type for the NUMA node represented by this NumaNode object.
Public property Cpus Gets a collection of Cpu objects that belong to this NumaNode object.
Public property GroupID Gets the GroupID that is assigned to this NUMA node.
Public property ID Gets the ID of the NUMA node that is represented by this NumaNode object.



  Name Description
Public method Equals (Inherited from Object.)
Public method GetHashCode (Inherited from Object.)
Public method GetType (Inherited from Object.)
Public method ToString (Inherited from Object.)



Access to the NumaNode object is though the AffinityInfo object that is contained in the Server object.


The following example shows how to display all the NUMA nodes on the local instance of SQL Server and the CPUs that belong to each NUMA node.

using System;
using Microsoft.SqlServer.Management.Smo;

    class Program
        static void Main(string[] args)
            Server dbServer = new Server("(local)");
            foreach (NumaNode node in dbServer.AffinityInfo.NumaNodes)
                //Display the AffinityMask, GroupID and ID of
                //each NUMA node.
                Console.WriteLine("AffinityMask: {0}\n" +
                                  "GroupID:      {1}\n" +
"ID:           {2}\n",
                    node.GroupID, node.ID);
                //Display the ID of each CPU that belongs
                //to this NUMA node.
                Console.Write("CPUS          :");
                foreach(Cpu cpu in node.Cpus)
                    Console.Write("{0} ", cpu.ID);
