A processor with memory installed into slots near this processor is called a NUMA node. NUMA systems are platforms with more than one system bus where each processor can access all the memory on the motherboard. In other words, NUMA is a method that determines how one processor interacts with the memory modules of another processor. Each processor has a priority to use “its own” local memory rather than using the memory installed into the slots near another processor. Time to access memory by a CPU depends on the location of memory on the motherboard. NUMA (non-uniform memory access) is the architecture for multi-processor systems that allows CPUs to share memory locally. Let’s take a closer look at the concept of NUMA and vNUMA. By default, vNUMA is enabled for all VMs that have 8 vCPUs or more to improve performance.
When you enable VMware Hot Add, vNUMA is automatically disabled for the VM. VMware Hot Add is disabled by default for different reasons. Note, however, that there are downsides to using this feature when hot adding is not really required. VMware Hot Add is a useful feature in many cases.

Some lower Windows Server editions support memory hot add only. The top Windows Server editions support both CPU and memory hot add. Guest operating systems that support Hot Add are Windows Server 2003 and newer, and Linux using kernel 3.8 and above.

You may need to buy additional licenses to run the software on a higher number of processors. Take into account the licensing limitations of the guest OS and applications installed on the VM before adding vCPUs. Refer to the VMware licensing guide to check available functionality for other editions and guest OSs.

VMware vSphere Enterprise Plus supports both CPU hot add and memory hot add.

The same logic applies to memory hot add and memory hot plug. You can notice that the CPU Hot Add feature is sometimes referred to as CPU hot plug. With VMware Hot Add enabled, there is no need to shut down a VM to add virtual devices. VMware Hot Add makes it possible to add a virtual CPU (central processing unit) and RAM (random access memory) on the fly. By default, you can add virtual devices such as a virtual hard disk (not IDE), network adapters, and USB devices while a VM is powered on.
VMware Hot Add is a feature that allows you to add virtual devices to a virtual machine while the VM is running.
