Virtualization

Good afternoon friends!

I already asked a similar question, the task is to calculate how many virtual machines with average characteristics:
Windows Server Datacenter,
4 GB of frames,
2 vCPU.

Manage to shove certain characteristics onto a physical server.

Are there convenient calculators for calculating?

Suppose I drive in the parameters of physical. server and get the approximate number of virtual machines? Or I drive in the necessary characteristics of 1 vir. and their number - issued physical. resources for the comfortable operation of all this?

Or what alternative methods of calculation?
Thank you!

if you have such a question, then you need to either hire an admin or score on this matter)

something you are saying some garbage , the
amount will be according to some parameter,
for example, you have 128 gigabytes of memory in your server, 4GB virtual machines will fit 128/4=?
you have 8 cores of 3,000 megahertz each, one virtual machine you have, say, 1 gigahertz, you have a total of 8 * 3000/1000 =?
you have 500 gigabytes of disk space, and you need 100 gigabytes for a virtual machine, you will fit 500/100 = ?

Well, what's the problem?
(RAM of one virtual machine * per number of machines) + 30% = number of RAM on hypervisors
CPU of one virtual machine * per number of machines = number of CPUs on hypervisors
This is simple arithmetic, what other calculators are needed here?

It all depends on the planned load, because all the machines at the same time are rarely 100% loaded on all fronts. Therefore, we must also understand why the data center is being created and what will be spinning there. Based on this data, plan servers and storage. Plus take into account the technical limitations.
Counting simply arithmetically can and is logical, but not for those who count money
