A stable, scalable solution that offers great compatibility with other operating systems

Pros and Cons

  • "The solution's compatibility is very good with multiple operating systems. The moving systems are very good and migration is excellent. These are the most valuable features for us."
  • "The solution should include some features that can help with converting raw files into different formats. It should offer better management around raw files."

What is our primary use case?

Our primary use case is testing any software by Proxmox.

What is most valuable?

The solution's compatibility is very good with multiple operating systems. The moving systems are very good and migration is excellent. These are the most valuable features for us.

What needs improvement?

The solution should include some features that can help with converting raw files into different formats. It should offer better management around raw files.

For how long have I used the solution?

I've been using the solution for two months.

What do I think about the stability of the solution?

The stability of the solution is very good.

What do I think about the scalability of the solution?

The solution is scalable.

How are customer service and technical support?

I've never been in touch with technical support so I can't speak to any direct experience with them. Their website, however, is very helpful.

How was the initial setup?

The initial setup was straightforward.

What other advice do I have?

We use the standard community edition of the solution. We use the on-premises deployment model.

The planning of the volumes is very important because if you're converting from one format to another, you can have some challenges there. I would advise others to plan the setup very, very well so that you do not have to migrate systems into different formats. That's the only challenge that we had.

I'd rate the solution eight out of ten.

A flexible and affordable approach, especially for on-site deployment

Pros and Cons

  • "Proxmox allows us to achieve affordable performance while keeping high levels of data protection and flexibility."
  • "This solution needs a more flexible and efficient backup solution in the dashboard."

What is our primary use case?

I use this solution as a virtualization and Linux container platform for a small-medium Enterprise. It's highly stable, flexible, expansible, and compatible. The characteristics of the software combined with the hardware performance allow for the deployment of services in many different and variable scenarios, especially on-site for companies that need this kind of deployment.

How has it helped my organization?

Proxmox allows us to achieve affordable performance while keeping high levels of data protection and flexibility. It also enables the deployment of services for small enterprises that need on-site deployment, and at the same time, it helps keep the budget under control. It maintains very low energy, noise, and steric footprint for the office environment.

What is most valuable?

For me, there are several features that I find valuable, including:

  • Use of open-source software.
  • Compatibility with simple Linux container solutions on the same hosts.
  • The integration of a simple and flexible backup solution.
  • The dashboard/control panel.

Worthy of special mention is the community, which is excellent at solving or explaining difficulties for the users of the solution.

What needs improvement?

This solution needs a more flexible and efficient backup solution in the dashboard.

The capacity for integrating deployment through WAN is needed. Something like a Federation tool for Central monitoring and management.

UPS supervision integration would be a nice feature because right now this has been integrated by ourselves using another tool that is not on the platform.

For how long have I used the solution?

Eight years.

What do I think about the stability of the solution?

Besides using the free unlicensed version, the updates are very stable. I have only had one reported incident in eight years. Systems are deployed in office scenarios.

What do I think about the scalability of the solution?

This solution scales relatively easily.

How are customer service and technical support?

I have never used the technical support. Instead, I have relied on the community.

Which solution did I use previously and why did I switch?

Prior to this solution, I used VMware VSphere 5 and 6, but it requires mostly professional (certified) IT equipment. The performance impact of the hypervisor and control panel is very heavy and it requires an independent backup solution. It also does not support Linux containers.

How was the initial setup?

The initial setup was relatively simple. We had a couple of servers and an iSCSI SAN, VLAN, and LACP Bonding with no HA.

What about the implementation team?

We performed the implementation in-house.

What was our ROI?

The time it took for us to see the ROI was very short.

What's my experience with pricing, setup cost, and licensing?

Proxmox is free software, but if you prefer the support and a more rested repository then you can pay for it.

Which other solutions did I evaluate?

I evaluated several products including Docker, HyperV, VirtualBox, and KVM.

An excellent choice for budget sensitive operations.

What is our primary use case?

We currently have more than 160 virtual machines and LXC containers on Proxmox in an all Linux production environment.  

How has it helped my organization?

Get the community level if you are on a budget --- keep your software updated to the latest releases.

What is most valuable?

Live migration. It is easier to balance loads across hypervisors if a given container or virtual machine uses more resources than its peers.

What needs improvement?

IMPORTANT - use separate physical network for Corosync/Heartbeat functions. This is obscure in the documentation - but you'll find it.

For how long have I used the solution?

One to three years.

What do I think about the stability of the solution?

Heartbeat was overwhelmed due to all hypervisors…

For how long have I used the solution?

One to three years.

What do I think about the stability of the solution?

Heartbeat was overwhelmed due to all hypervisors running a single NIC - nodes started to fence themselves when load was high.

What do I think about the scalability of the solution?

Use best practices for network segregation - management / heartbeat / live migration / Ethernet-based storage should be on different networks (VLANs).

How is customer service and technical support?

N/A.

How was the initial setup?

Very straightforward.

What about the implementation team?

In-House.

What's my experience with pricing, setup cost, and licensing?

The cost is excellent. An excellent choice for budget sensitive operations.

Saves a lot of time compared to imaging physical desktops

Pros and Cons

  • "We now have the ability to quickly build and deploy VM desktops for application testing with the snapshot ability to rollback, as required."
  • "Saves a lot of time compared to imaging physical desktops."
  • "The template option allows us to build a desktop in a VM, then quickly deploy as a linked clone."
  • "Some of the more advanced features and options required for setup still need to use the console and hand edit config files."

What is our primary use case?

I needed a free virtualization solution for training, development work, and application testing with the ability to quickly deploy VMs based on a single VM template and snapshots.

How has it helped my organization?

By implementing Proxmox, we now have the ability to quickly build and deploy VM desktops for application testing with the snapshot ability to rollback, as required. Saves a lot of time compared to imaging physical desktops. The web interface is quick to learn for techs to deploy VMs based on templates, as required.

What is most valuable?

The template option allows us to build a desktop in a VM, then quickly deploy as a linked clone. The hard drive file on the template is used (read-only), then all changes are saved in a separate hard drive file. It is like deploying a new VM based on snapshots.

What needs improvement?

Some of the more advanced features and options required for setup still need to use the console and hand edit config files.

For how long have I used the solution?

Less than one year.

What do I think about the stability of the solution?

No issues.

What do I think about the scalability of the solution?

No issues.

How was the initial setup?

initial setup was a bit of a learning curve, as with any new product. Some of the configuration required uses the console and options were not available in web interface (like setting MTU on NICs).

We have developed a tried and tested method to set up servers and it works well once you know how you want your servers to work.​

What is most valuable?

It's a solid, stable and powerful open source virtualisation product that has allowed us to bring virtualisation to smaller SMBs at an affordable price.

How has it helped my organization?

All our client servers are now virtualised, which has reduced the risk of downtime due to a server failure that used to happen with non-virtualised servers. Servers can be backed up using snapshots etc.

What needs improvement?

Storage IO management seems the weakest link although this could be hardware related. On decent servers this is not an issue but on smaller custom built servers we have occasionally had issues with IO speed. It is a well thought out product and the newer versions just seem to get better n better.

For how long have I used the solution?

We've been using it for seven years.

What was my experience with deployment of the solution?

There have been no issues deploying it.

What do I think about the stability of the solution?

There have been no issues with its stability.

What do I think about the scalability of the solution?

We haven't had any issues scaling it for our needs.

How are customer service and technical support?

I've never really needed it as I've been able to work out most things intuitively.

Which solution did I use previously and why did I switch?

We also looked at VMware. Our perception is that this is a superior product but that is subjective as it is not mainstream.

How was the initial setup?

It's straightforward. We have developed a tried and tested method to set up servers and it works well once you know how you want your servers to work.

What was our ROI?

It's hard to quantity but using Proxmox has significantly boosted our server capabilities and service offering increasing our revenue.

What's my experience with pricing, setup cost, and licensing?

It's open source and provided one has enough experience with Linux and servers it doesn’t cost much other than time to become an expert in the product.

Which other solutions did I evaluate?

We also looked at VMware.

What other advice do I have?

It's well worth using. It's highly recommended and we have had no issues.

Performs well with Windows but lacks Mac support due to Mac's EULA
With respect to some of the cons, Proxmox VE performs well enough with Windows if you use KVM's virtio devices in lieu of emulated hardware. However, the freely available virtio drivers are not WHQL-certified, which produces annoying error messages when you attempt to load them. With respect to the lack of Mac OS X support, a large part of this is due to Apple's terms of use for OS X. I can't really blame Proxmox or the KVM folks for not pursuing Mac OS X support since doing so would violate Mac OS X's EULA and could potentially get them or their customers sued. Lastly, I can't say that I've ever had any stability issues with the Proxmox VE web interface, but using the graphical console can be a struggle. I don't think I've gotten it to work in anything except Mozilla Firefox.
