Proxmox vs ESXi/vSphere: What is your experience?


Does anyone have experience comparing Proxmox 6 vs VMWare ESXi/vSphere 6.7?

I'm a systems engineer at a very large systems integrator in Europe. I need to evaluate the differences between Proxmox and VMware. What can you share with me?

Thank you,

This is with reference to your email if you technically compared, Proxmox is new in the market and it is easy to manage but as far as support concerned I would suggest buying standard Proxmox support if it is a new installation. As you are aware, VMware is too costly in terms of license.

To summarize, Proxmox is easy to manage and better. Kindly find some Authorized Proxmox partner in your country and get initial support.

In my experience, Proxmox is a very good product, comparable with VMware. We can argue about VMware being fancy and popular these days but PM does the job for a fraction of the cost. Just get some reasonable hardware to get started and see for yourself.

If you have strong knowledge of Linux, Proxmox is the best solution, but you should have a strong Linux expertise. You can also add some georedundancy solution like LINBIT, it depends on what you need. How many servers do you want to migrate? are you looking for an HA solution or just VM solution?

We are using VMware from the last 10+ years and do now have exposure on Promox VE.

We have downloaded it to evaluate and compare.

I don't have experience with Proxmox but since it uses KVM and brings with great improvements, I propose you to use the comparison between VMware vSphere and KVM. And the KVM advantages are that you add those powered by the whole Proxmox features portfolio.

I really can’t really comment on Proxmox as I have not worked with it before but I can share on VMware ESXI 6.7.

We have been using VMware Esxi for 7 years I can say this has been the best hypervisor for us since we use VMware and Veeam for all our replication, backups and VMotion for migrating our servers from one host to the other in realtime without affecting any currently running operations.

We find our operations being smooth and more efficient on VMware ESXi 6.7 hypervisor and I can say it’s a very stable platform for us and I would highly recommend it in any organization. The most benefits that come with VMware ESXI 6.7 is that it supports all 2019 OS versions like Windows server 2019 which was not supported in the previous version. We also noticed an increase in vCenter access and performance which was a plus for us when using VMware ESXI 6.7 compared to the previous 6.5 version.
