Switched from Citrix XEN and EMC VMWare: No downtime when node needs service but web interface could be simplified

What is our primary use case?

It is implemented in several Private Cloud Data Centers, from 5 to 16 nodes, from 256 GB RAM to 1 TB RAM, all using Supermicro Systems, running SQL servers, Application Servers ( SAP, Prothevs and some tailored Apps developed in house ) VDI and Files Repositories . all smooth and trouble free .

How has it helped my organization?

With live migration, there is no downtime when any node needs service or upgrades. Plus, when I need more memory, I just allocate it; more disk space? same. It is possible to administer almost anything remotely, now it takes months till a customer needs a weekend visit to service something, before Proxmox, it used to happens once a month!

What is most valuable?

Live migration :

Is simplifies the daily work, and reduces the downtime to nearly 0 .

Clonning and Snapshots :

Verry useful for development testing and backup .

Histogram about i/o, memory, CPU and network usage :

Helps to find the issue when some VM are running in some kind of bottleneck .

What needs improvement?

Mostly simplify web interface, simple things like the use of right mouse button to change VM attributes, make it more intuitive, but it is just cosmetic improvements, the core functions are all there.

Version 6.x improved the support for Containers to the PRO level .

For how long have I used the solution?

re than 10 years, since version 1.6 all the way to version 6.2 

What do I think about the stability of the solution?

Never had any issue with stability, even in the very earliest stages of development...

What do I think about the scalability of the solution?

Not for now, the 16 nodes per cluster limit have been removed in the 5.x release !

How are customer service and technical support?

Customer Service: OK, in fact the little we've used it, the site documentation was really good.Technical Support: Same as above.

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

Yes, Citrix XEN Server and EMC VMWare Server. I left Citrix for security, there are too many "black box" in the binaries that cannot be audited. In the VMWare case, for licenses politics, it uses a "per socket" schema that punishes high density servers with 2 or 4 sockets .

Is is the tool of choice used in the entire Facebook infra-structure, so it must be "at least" good enough .

How was the initial setup?

The first test was a little complex, in the time of the 1.4 version, but since the 2.0 version it is extremely simple, takes less then an hour to deploy a node and connect it to an existing cluster.

The 6.x release made things even easier, most maintenance tasks are now in the web interface

What about the implementation team?

I am an IT consultant, and I do everything myself (with my team, we are 4 people!)

What was our ROI?

Outstanding, worth every single cent spent on it!

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

The deployment itself cost nothing, it is Opensource software! The monthly subscription costs 17 euros per node, and it covers anything we needed so far...There are more options, but it is more then our customers needed until now .

Which other solutions did I evaluate?

Several, From Red Hat to Ubuntu, and everything I can find with a Google search, I spent 6 months with these research and tests!

The Facebook contract came well after this tests .

What other advice do I have?

Do it! The simplicity will surprise you!

Free, flexible, easy to implement; it's based on KVM and independent nodes are a great feature
Pros and Cons
  • "Less infrastructure required; simple to use."
  • "Lacking in enterprise features."

What is our primary use case?

This is a free version of VMware and that's why we're using it. It does everything that VMware can do and it's more flexible. We were looking for a virtual solution and we're a startup, so the cheapest is best. We are customers of Proxmox and I'm the technology operations manager. 

What is most valuable?

The feature I like best about this product is the fact that they have independent nodes. Proxmox is based on KVM and essentially you could lose a node. All the hosts that are running are evacuated elsewhere in the cluster and away you go. I have reduced infrastructure and I'm familiar with it because at the heart of the hypervisor is Debian Linux and I'm a Linux administrator. It didn't require learning a whole new platform and it's so easy to use. Proxmox will be in my toolbox forever, I love it.

This is a really great solution and the more VMware raises their costs, the more appealing it is. I'd be very nervous if I were one of the big companies because you're going to have administrators like myself discovering Proxmox and the cost is zero. With this solution, when something goes wrong, you Google it, you figure out the problem and fix it. Of course if you're an enterprise company, that's something else.

What needs improvement?

The product should have more enterprise features, perhaps DRS. I don't think Proxmox has the ability to sense that a host is running hot and needs to be evacuated. So DRS, dynamic resource scheduling, is a feature that constantly monitors the host and if it sees a particular host taking up a lot of resources, it will take that host off and throw it on a different host in the cluster that's not running as hot and doesn't have as much utilization. It protects the overall cluster 

As above, I think the DRS would be a helpful additional feature.

For how long have I used the solution?

I've been using this solution for six months. 

What do I think about the stability of the solution?

As long as you're monitoring your host yourself, it's a stable solution. 

What do I think about the scalability of the solution?

I can't really speak to the scalability. I haven't looked into it yet. We're a very small company and we have about five people using the solution, all at the director or senior level. We have a senior application developer, and a director level manager who brought the product in.

How was the initial setup?

Does a three and a half minute setup sound reasonable to you? When I first installed it, I thought there must be more to it. I downloaded the ISO onto a thumb drive and made it bootable. Then you boot the server, boot off the thumb drive. You have to answer about six questions and that's it. Very simple. 

What other advice do I have?

My only recommendation to anyone thinking of implementing this solution is to read up on it, but give it some serious consideration because it really is a great product. In other words, don't let the freeware label scare you off.

I would rate this solution a seven out of 10.

Great affordability, scalable, and stable
Pros and Cons
  • "The affordability of the solution is the product's most valuable aspect."
  • "The initial setup has a pretty steep learning curve."

What is our primary use case?

We primarily use this solution to cover anything that VMware does.

How has it helped my organization?

The solution has made it so that I can operate things without having to spend thousands and thousands of dollars. It's saved my company a lot of money.

What is most valuable?

The affordability of the solution is the product's most valuable aspect.

What needs improvement?

The so-called free support that the solution offers doesn't allow you to access the repositories. If they would allow that access like they say they do it would be better. It does work for about a week and then it times out and never works again.

It would be preferable if they had a different viewing product other than VNC.

The initial setup has a pretty steep learning curve.

I'd like to see more high availability capabilities.

For how long have I used the solution?

I've been using the solution for a couple of years.

What do I think about the stability of the solution?

The solution is very stable. That's not a problem. I can't recall dealing with bugs or glitches. It doesn't crash or freeze.

What do I think about the scalability of the solution?

The solution is scalable. If a company needs to expand the service, it can do so easily.

We just have a handful of users on the solution. However, it fluctuates. Many users handle web servers and virtual guests.

How are customer service and technical support?

Technical support has room for improvement. It would be nice to be able to call them and have conversations with them during stateside hours. Right now, that's not possible. Right now, it's more run through email and chats.

I'd rate their service seven out of ten. It's okay, but it could be better if calling them directly was an option.

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

We previously used Hyper-V and VMware, however, we switched to this solution mostly due to the costs involved in running the other options.

How was the initial setup?

The initial setup isn't too bad, however, it's a bit complex. There's definitely a learning curve for people implementing it themselves.

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

The solution is very affordable in comparison to competitors.

What other advice do I have?

We're simply customers. We don't have a business relationship with the solution.

We're currently using the latest version of the solution.

We use both cloud and on-premises deployment models.

The solution isn't too bad, and not too hard to figure out. Users considering taking on the solution can just watch some videos and train up a little bit. It will make it easier when it comes to setting everything up and understanding how to handle the solution.

I'd rate the solution nine out of ten. It would be great if there was someone available in stateside hours instead of just German hours. Other than that, it offers pretty much everything we need at a pretty great price.

Straightforward to set up with good documentation and ROI
Pros and Cons
  • "The initial setup is straightforward."
  • "I can't speak to any improvements. It is not lacking features."

What is our primary use case?

I am using it to virtualize microservices.

What is most valuable?

I'm using only a single server, so I have no need to replicate VMs.

The initial setup is straightforward.

The stability is good.

You can scale the solution.

The documentation is great.

If you have problems, you can find answers on their website.

What needs improvement?

I can't speak to any improvements. It is not lacking features.

For how long have I used the solution?

I've been using the solution for three years. 

What do I think about the stability of the solution?

The stability is very good. It's reliable. There aren't bugs or glitches. It doesn't crash or freeze. 

What do I think about the scalability of the solution?

I haven't had any problems with scalability. I'm using it on a server with 256-gigabyte memory and large hard disks and it's doing just fine.

Aside from the people using the website, just I use the solution.

We likely will increase usage in the future.

How are customer service and support?

I've only used their website when I've had questions. I've never spoken to anyone directly. Therefore, I can't speak to personal experience with technical support.

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

We previously used VMware. I switched due to the fact that I wanted to try something different.

How was the initial setup?

The initial setup is not overly complex. It's very straightforward, very simple. 

I had a server that I needed to expose to the internet and I just decided to use it instead of VMware and it worked.

You only really need one person to handle maintenance, however, we have two people on staff that can handle those types of responsibilities. 

What about the implementation team?

I handled the initial setup on my own. I did not need to use an implementation specialist or consultant. 

What was our ROI?

I've seen a very good ROI.

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

As soon as I need to go with collaboration and the networking of more than one server, I'll probably go to their licensing plan.

Which other solutions did I evaluate?

I just went directly to this product. I'm aware of other possibilities, KVM and others, however, I decided on Proxmox as it had a good following and good documentation.

What other advice do I have?

We are just a customer and an end-user.

While version seven is available, I haven't used it yet.

I'd rate the solution at a ten out of ten.

Easy to deploy and allows us to run services without using dedicated hardware
Pros and Cons
  • "The most valuable feature is the ease of deployment."
  • "There are some things that need to be done using the command-line interface, and these should be moved into the web-based interface."

What is our primary use case?

There are a number of services that we need, such as a dedicated phone system and an Active Directory server, that we run in a virtualized environment. Doing so means that we don't need to use dedicated hardware for them.

How has it helped my organization?

This is a low-use, but a high-need solution for us. It is helpful because it means that we don't need dedicated hardware for all of our services. It has allowed us to grow the way we have, over the past couple of years.

What is most valuable?

The most valuable feature is the ease of deployment.

For the most part, it is quite user-friendly.

What needs improvement?

The interface can be a little bit rough in places. There are some things that need to be done using the command-line interface, and these should be moved into the web-based interface. There are also aspects related to storage that are difficult to do with the interface.

For how long have I used the solution?

We have been using Proxmox for between two and three years.

What do I think about the stability of the solution?

We have had absolutely no problems with stability.

What do I think about the scalability of the solution?

Scalability is excellent and it seems to run with quite a low overhead.

I have been experimenting with adding nodes to the cluster so that we can create more of a high-availability system. The process is just a matter of installing the software and then copying and pasting the license key. It couldn't be easier.

How are customer service and technical support?

I have not had problems that necessitated contacting technical support.

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

I did not use a similar solution prior to implementing Proxmox.

How was the initial setup?

The initial setup is easy.

What about the implementation team?

I am the person who is responsible for configuring and maintaining Proxmox.

What other advice do I have?

This is a product that I recommend trying. There are others that are bigger and better, albeit priced accordingly. This should definitely be tried and put through its paces.

Overall, this is a good product, although there is always room for improvement.

I would rate this solution an eight out of ten.

Very stable and doesn't require more resources for memory RAM, but some processes are not automatic
Pros and Cons
  • "Proxmox is free, very stable, and doesn't require more resources for memory RAM. It's fine for a small data center."
  • "One issue with Proxmox is that some processes are not automatic. For some processes, you have to do it manually by command line."

What is our primary use case?

With Proxmox, we use the hypervisor of Proxmox and Proxmox backups. In VMware, I see all the production, like vSphere, vCenter, vRealize Operations Manager, vSAN, Workspace ONE, and VMware Horizon. Right now we are working with NSX. 

For VMware, as a partner, I have many cases of vSAN as a hyperconvergence solution. This solution is very popular in my country, mostly with banks. There are many solutions that we have implemented and that are very successful. Horizon is another solution that is highly requested by clients. Because of the pandemic, the VDI and Remote Desktop are often requested from our clients. Those two are very good solutions. From my experience, I don't have many problems with them.

What is most valuable?

Proxmox is free, very stable, and doesn't require more resources for memory RAM. It's fine for a small data center.

What needs improvement?

One issue with Proxmox is that some processes are not automatic. For some processes, you have to do it manually by command line. I don't know about the last version of Proxmox, but I had that problem with this version.

For how long have I used the solution?

I've been using this solution for one year. In my last job I was a final client, so I worked with vSphere and the vCenter. I did a migration from vSphere to Proxmox, and I was in charge of this infrastructure using Proxmox. I am working for a partner of the VMware product as a presale VMware specialist.

Most implementations are on-premise. We really don't have implementation on cloud. I'm from Bolivia, and we recently have been introducing on-cloud solutions, but most of the solutions are on-premises.

What do I think about the stability of the solution?

Proxmox is very stable.

How was the initial setup?

For deployment, we used eight blade servers.

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

Proxmox is is free.

Which other solutions did I evaluate?

I've worked with VMware, vSphere, vCenter, and vRealize Operations Manager. VSphere works perfectly. The enterprise version is very complete, and you get almost everything you need in data center.

What other advice do I have?

I would rate Proxmox VE 7 out of 10.

Easy to install, stable, and scalable
Pros and Cons
  • "It is easy to deploy."
  • "We are using servers individually, and we are looking for a reliable application that allows us to hop between servers with high availability."

What is our primary use case?

We use this solution for our file servers. Most of the applications are file servers and some are employed as web servers for internal applications that we use.

What is most valuable?

Most of what we use is for file servers and for some internal web server applications for local use. 

It is easy to deploy.

What needs improvement?

We are using servers individually, and we are looking for a reliable application that allows us to hop between servers with high availability. It is one of our primary goals to have a hyper-converged solution. With the high availability, we can make some hop-switch deployment teams between our servers.

It could be more user-friendly with the configuration.

For how long have I used the solution?

We have been using Proxmox VE for almost one year.

We are using Version 6.3.

What do I think about the stability of the solution?

We have no issues with the stability of Proxmox Ve.

What do I think about the scalability of the solution?

Proxmox VE is a scalable solution, but we are not necessarily interested in expanding our usage. We want to make some changes to something that is more reliable.

How are customer service and technical support?

We have no support from Proxmox VE. Our support is from the internet. It would be helpful to have some support included.

How was the initial setup?

The initial setup is easy and straightforward. We set it up locally.

Our team does the configurations.

It takes a couple of days to deploy.

Which other solutions did I evaluate?

We are looking for another Hypervisor similar to VMware.

What other advice do I have?

Proxmox VE is a great solution for small enterprises for small businesses. I'll recommend it just for that use.

I would rate Proxmox VE an eight out of ten.
