[SOLVED] CPU upgrade for 24/7 virtualization setup

[sevvvvv]

Hi folks, my current setup is a
i7 7700 3.6
64gb RAM ddr4
2xmicron 500gb SSD.
Intel HD graphic 680
running w10 64bits

I currently use vmware with 12 vm´s (all w10 x64), all of them running a small app connected to a proxy,not demanding much (around 60%RAM and 30% CPU)
Each is configured with 2.5 GB ram,2 cores and 20GB data.

With this running the host CPU usage is around 15-25% most of the time and RAM 60%.

I know this quad core cpu is not the best for virtualization and Im willing to updgrade my machine since I plan to be adding vms every week possible to the point of running 30-40 at a given point.

My current options in terms of CPU are:
Intel® Core™ i7-8700 Hexa-Core (not that much of upgrade)
AMD Ryzen 7 1700X Octa-Core
Intel® Xeon® W-2145 Octa-Core Skylake W
AMD EPYC 7401P 24-Core (may be overkill?)

Also will indeed add more ram and ssd storage if needed.

Scaling up to "30-40 at a given point" indicates a second physical system.
Split that in half...15-20 on each box.

You are obviously doing some commercial activity. I agree with @USAFRet, get a second physical box. That way if one dies, you still have 1/2 your capacity.

Yes thats also other possibility.

I dida test of adding 5 more win10 vms (2gb ram each) , so 17 total and the host cpu usage fired right away from 25% to almost 80% for a few minutes.
Now its back to 20-30% with all 17vm running, it doesnt make sense probably rainmeter/taskmanager can´t exactly evaluate how much cpu is being used by vmware.
Anyway I think the limit is around the corner since changing between vms is getting slower and vmware sometimes not responding for a few seconds.
