26.01.2015 · The reason you used to have the option to select sockets vs. cores was to get around a limitation in the guest OS. For example, Server 2008 will only use up to 4 physical CPUs. By increasing the number of cores per socket, you can raise the number of CPUs the guest OS will allow you to use (since it seems them as cores).

23.04.2018 · 1 Solution. 04-23-2018 02:07 PM. processors/sockets is used for the physical processors in the host. Each of these processors have a number of cores, and likely supports Hyper-Threading. In this case a host with 2 x 10 core processors, and Hyper-Threading enabled will shows up with 40 logical CPUs.

Warning! A very important part of understanding this is that when you configure a vCPU on a VM, that vCPU is actually a Virtual Core, not a ...

Understanding The Terminologies

VMware introduced multi core virtual CPU in vSphere 4.1 to avoid socket restrictions used by operating systems. In vSphere a vCPU is presented ...

Nov 09, 2012 · You add 2 socket. That's 2 core. You make them 2 core PER socket, now you have 4 core machine. In virtual environment, a socket is by default 1 core. You can replicate a VM to be identical to a physical server to test performance, but just start with the basics. Forget core. Think of VM's as having sockets. Only change sockets, start with 1.

Jun 08, 2021 · When you edit the CPU properties, you can set the number of CPUs and then the sub-option is cores per socket, rather than cores per CPU. Since the upper definition is CPUs, why not make the sub definition match? When it comes to setting a CPU/core relationship within a VMware workload/virtual machine be careful using cores at all.

Always configure the virtual machine vCPU count to be reflected as Cores per Socket, until you exceed the physical core count of a single ...

For older vSphere versions, I recommend using sockets over cores in VM configuration. At first, you might not see a significant difference in ...

Jan 11, 2012 · In VMWare is does not make a difference. It is purely based on how the cpu's are presented to the guest. Whether you choose dual sockets single core each, or single socket with dual core, VMWare treats those as the same, you get 2 cores of CPU time. The main reason this was added was for software licensing on the guests.

13.01.2022 · Back then, the relationship of socket vs. core vs. CPU vs. thread was 1:1. ... When it comes to setting a CPU/core relationship within a VMware workload/virtual machine be careful using cores at all. For example, with vMotion, I can move a VM from a 6 core/CPU host to a 12 Core/CPU host and vice versa.

thanks , esx host like below: btw, already checked hot-add cpu inside VM. what do you recommended? 16 sockets by 1 core per socket 2 sockets by ...

There is no difference as long as VM has same quantity of cores of CPU. · It's recommended to configure with fewer socket and more cores because ...

09.05.2012 · 05-09-2012 09:11 AM. In general, this depends on the OS and applications. VMware multicore virtual CPU support lets you control the number of cores per virtual CPU in a virtual machine. This capability lets operating systems with socket restrictions use more of the host CPU's cores, which increases overall performance.

May 09, 2012 · VMware multicore virtual CPU support lets you control the number of cores per virtual CPU in a virtual machine. This capability lets operating systems with socket restrictions use more of the host CPU's cores, which increases overall performance. You can configure how the virtual CPUs are assigned in terms of sockets and cores.

I believe in the physical world performance wise it was better to have multiple cores in a CPU versus two separate single core CPU's. (Something about sharing a ...

The ESXi host hardware comprises of a dual socket Intel Xeon E5-2650v4 2.20GHz 12 core CPUs with hyperthreading enabled and 256GB of RAM (128GB ...
