本文介绍了一种通过软件实现非统一内存访问(Soft-NUMA)的方法，并详细展示了如何在不支持硬件NUMA的系统上配置Soft-NUMA节点，以及如何为SQLServer实例分配CPU资源，进行数据库分区和优化。

reference concept

Soft-NUMA - software non-uniform memory access

Consider the following example. A computer with eight CPUs does not have hardware NUMA. Three soft-NUMA nodes are configured. Database Engine instance A is configured to use CPUs 0 through 3. A second instance of the Database Engine is installed and configured to use CPUs 4 through 7. The example can be visually represented as:
CPUs 0 1 2 3 4 5 6 7
Soft-NUMA <-N0--><-N1-><----N2---->
SQL Server <instance A ><instance B>

With the file groups created, tables to be loaded with data were placed in the file groups, for example,
create table ORDERS_6
