Proxmox Sizing CPU and Memory
A question often asked when it comes to creating virtual environments is how much CPU or memory will be needed in each node and how much to allocate per virtual machine?
It is a fact that we will, and often do, run out of memory much sooner than CPU for a given Proxmox or any other host node.
In this video, I will show you some guideline and best practices to handle that question.
Single socket versus multi-socket
--------------------------------------------------------
A multi-socket node will always have better performance than a single socket, regardless of the number of cores per CPU
a quad-socket node will provide the maximum performance of any socket configuration node
Hyper-threading – enable versus disable
-----------------------------------------------------------------
One of the major differences between Intel and AMD is hyper-threading. All cores in AMD CPUs are true cores, whereas all Intel CPUs have hyper-threading, which creates two virtual cores per physical core.
it appears that it is better to leave it on for newer Intel servers
Start small with VM resources
-------------------------------------------------
A virtual machine is completely different from a physical machine and it needs to be treated as such. They do not consume CPU and memory like a physical node does. The best practice is to always provision CPU and memory resources sparingly, and then increase them as you see the application's performance.
When allocating vCPU for a single VM, never exceed the total number of cores in the node.
This will degrade the performance of the entire node and all VMs in it.
Keep in mind that in a virtual environment, more CPU and memory for a
virtual machine does not always mean better performance.
