Proxmox VE

What do you like best?

The features I like best right now are:

ZFS usability - Storage flexibility options

Clustering - one to as many servers as you need for your scalable infrastructure

Using hardware passthrough

Light weight OS

Flexibility, install on old and new hardware!

In the few years I used this software I never had a kernel panic. This software just simply works and is a great platform to get in on as a beginner as they have a community / free edition. Learn this platform it will get a good base and understanding of Hypervisor style operating system. Then take that knowledge even further, especially as ESXI / VM ware has changed their licensing model. I rate this from Entry Level to expert, use in any and all cases!

What do you dislike?

With the use cases I use it for, I have honestly at this time not come across any down sides to this Operating System. It is very well built.

Recommendations to others considering the product:

Just dive in. Grab an old box you have lying around and install it, play with zfs, clustering, and hardware passthrough, get to know the environment!

Install the os on a small SSD or even a usb drive use mass storage for vms (Obviously).

I would recommend a minimum of a 4c to 4c/8t CPU, 8 to 16GB Ram, 1TB for VM's

What problems are you solving with the product? What benefits have you realized?

Scalable solutions for constantly growing customers grow,

but also the ability to reduce the amount of physical servers.

Teaching Hypervisor technology to new technicians.
