Which hardware to choose for a simple hypervisor?

Question

Iron

Hello. I'm going to say right off the bat, noob question .
I have never worked with a hypervisor, and now I wanted to.
The question is, what is better suited for the following task:
- Free version of ESXI
-CentOS for ZABBIX + Mysql for it (I will monitor about 15 machines + 30 devices)
-CensOS Asterisx + Elastix (Total 8 ip phones locally)
-Win 7 To run small network programs in Python
In the future, perhaps some other weak machine on win7
For such a task, something cheap like
an old server with 2 * Xeon E5345 8g of memory or better
some kind of I5-4460 + 8g of memory is suitable
or is it generally a stupid idea and it won’t work will?
In theory, the server should be able to handle it, 2 cores per machine + 2 gigabytes per server (you can use 3 gigabytes under Win)
, this should be enough for each machine, I now have Asterisk on much better hardware without any problems.
Tell those who know! Thank you!

Answer 1

It will work even on very weak hardware.
The only problem is the capriciousness of ESX in relation to network cards and disk controllers .
You can see about hardware by googling "whitebox ESXi"
