9 Μαρ 2017 · When a virtual machine is sized larger than a single physical NUMA node, a vNUMA topology is created and presented to the guest operating system. This virtual construct allows a workload within the virtual machine to benefit from physical NUMA, while continuing to support functions like vMotion.
Virtual NUMA topology is available to hardware version 8 virtual machines and is activated by default when the number of virtual CPUs is greater than eight. You can also manually influence virtual NUMA topology using advanced configuration options.
Virtual NUMA Controls. Download PDF. Feedback. Updated on 05/31/2019. For virtual machines with disproportionately large memory consumption, you can use advanced options to override the default virtual CPU settings. You can add these advanced options to the virtual machine configuration file. Parent topic: Using Virtual NUMA. Previous Page.
25 Οκτ 2016 · Windows Server 2012 introduced support for projecting a virtual NUMA topology into Hyper-V virtual machines. This capability can help improve the performance of workloads running on virtual machines that are configured with large amounts of memory.
20 Αυγ 2021 · Using Virtual NUMA vSphere includes support for exposing virtual NUMA topology to guest operating systems, which can improve performance by facilitating guest operating system and application NUMA optimizations.
Virtual topology simplifies a virtual machine’s CPU assignments by exposing the appropriate topology at various levels. These topology levels include virtual sockets, virtual non-uniform memory access (vNUMA) nodes, and virtual last-level caches (LLC).
vNUMA, for virtual NUMA, is a virtual machine that presents a cluster as a virtual shared-memory multipro-cessor. It is designed to make the computational power of clusters available to legacy applications and operating systems.
