Proxmox VE vs. Scale Computing Platform

We used Proxmox to implement private cloud services, for clusters
of a small number of servers, from 3 to 11 with and without high
availability. Allways with ZFS file systems, and we used to install the
root pool in SSDs mirrored and use other pools with RAID 10 in groups of
four, for the virtual machines and containers, for the backups and snapshots, we used magnetic disks with RAID 10, in groups of four. Do
not use an even number of servers because does not facilitates the
implementation of High Availability, because the corosync service must
have an odd number of servers to detect a failed server for the quorum
system. We used a variety of servers, from clone PCs with AMD Ryzen with 6 cores and 12 threads with 64 GB of RAM no ECC, to high end servers with 64 cores and 128 threads per cpu and 2 cpus per server, with AMD EPYC Rome or Milan, 2 terabytes of RAM ECC.

I would recommend it to anyone who has three or more servers. We just received another quote as I am about to deploy Scale at City Hall as well. This will replace my 8-year-old VMware cluster that hosts 20 servers.

• BackUp System, provides extensive propiertes and verifications. An exclusive server for BackUp Administration (PBS)
• Hardware Customization. You can select several properties to adapt the hardware to your needs
• Easy administration. You will be able to manage the server with easily accessible tools such as the web console and usage statistics.
• Certificates Administration.

• Snapshots are lean and fast, so restore time is simply amazing. When you don't have time to wait after a crypto attack to restore, I have found nothing faster!
• Clients can never fully know their growth for years to come, and sometimes it is only a year after the original install. This is no problem we can build on to the system like Lego blocks. Just simply adding a node or two and there is no downtime!
• There are many functions that can be done while servers are running that help to maintain the most uptime, as an example disk size on the primary disk can be expanded without shutting down the server.

Incentivized

• Can't manage ZFS replication or snapshots as easily as I'd like
• Encrypted disks aren't easily deployed in VMs
• Moving disks between VMs is not automated

Incentivized

• It exposes no backup API. You have to treat VMs as physical machines, with all the drawbacks. This is a huge problem, since the official partner Acronis can't deliver. If you ever worked with Veeam you want it back very very badly.
• Assigned RAM is used RAM. The hypervisor can't share memory or only allocate what is used etc. It's wasted RAM most of the time.
• No logging and auditing. (There is, but not visible to the customer).
• The GUI is quite bad. It looks like done by a designer instead of an IT expert. But it's improving constantly.
• The company relies heavily on KVM, but seems to have no developer in the open source community. This leads to answers like "we can't do anything about QEMU drivers". Yes, you can. Have delevopers working on it.
• You can't do basic things like list all of your VMs and see how much RAM/disk, etc. they are using (e.g. in a list view).
• No rules on which VMs start on which nodes, which VMs to prioritize, etc.

Proxmox VE provides the most capable, yet stable virtualization platform in the market today. Licensing options are also competitive and cost-effective for support, and support is extremely fast and knowledgable of getting issues resolved as quickly and soundly as possible.

Since I have had no issues with downtime; easier management of my cluster and the ability to lower the number of devices in my Infrastructure, I will gladly renew my support contract with Scale Computing HC3 and upgrade my equipment with them when it comes time for it.

Out of every product I have used for this, Proxmox VE is the most concise, clear, and functional I have ever seen. I continue to use Proxmox VE even after occasionally comparing alternatives available because of it's usability, design concept, and great support of features. It's very unlikely I will find a product that can even compete with Proxmox VE in every angle of what Proxmox VE provides.

Everything you need to do is point-and-click easy. If you are the kind of admin who wants to edit every config file and endlessly customize your environment, then Scale may not be for you. On the other hand, if you just want it to work really well, and do what they told you it will do, then Scale is the ideal system.

Proxmox VE's ha-cluster functionality is very much improved, though does have a not-very-often occurrence of failure. In a 2-node cluster of Proxmox VE, HA can fail causing an instance that is supposed to migrate between the two nodes stop and fail until manually recovered through the command-line tools provided. Other than this, the HA clustering capability of Proxmox VE has proven to be reliable in 3 or more clustered environments with much less chance of these failures to occur.

Incentivized

Never had an outage or an error. Once a hard drive failed, but Scale kept on working flawlessly without interruption.

Incentivized

Proxmox VE's interfacing is always fast to load, both the Web interface and the command-line tool interfaces. Reporting is practically real time almost all the time, and you can see everything in mere seconds, easily able to identify if something is wrong or it everything is in tip-top shape as always desired

Performance has been just as outstanding as reliability. I have never experienced delays in any aspect of usage.

They are fast, understanding, very intelligent, know their product very well, fast, responsive, and concise. Need I say more?

The support team deserves major props for how cordial and professional they were with our implementation. We were assigned a project manager and engineer. Everything was scheduled with our kick-off call, and our engineer got us up and running in no time.

I did not do in-person training.

Incentivized

Because Scale is so simple, the training is just as quick and easy.

It worked, was easy and super fast to deploy, and provided everything we needed in a matter of minutes

Incentivized

The implementation was very easy. We had Scale support on standby and they were ready and eager to help if needed. The process went so fast the employees in the organization did not even know it was done.

Proxmox VE is cheaper than VMware, especially upscaling an HA architecture. Compared with other free or less expensive solutions, Proxmox VE is high compatible with more types of hardware solutions and more VM types. From my point of view, Proxmox VE has no competitor at the same price level, it offers the most complete and production-ready HA solution.

Incentivized

At the end of the day, and in the environment we are in, Scale just fits the bill, both price-wise and functionality-wise. Upgrading our VM environment was always a week-long process, now, it is a twenty-minute process, implementing, converting VMs, and rolling everything over to Scale was completed in less than a week's time, and that included training.

Incentivized

Proxmox VE provides everything you need to quickly add new storage mediums, network and local, as well as networking interfaces, such as using Linux standard bridges and now Open-vSwitch bridges which can be even more scalable than before. Proxmox VE 4.0 dropped support for OpenVZ in favor of the more well supported and native LXC and made an upgrade path to it very simple.

HC3 is one of the best products I have purchased for our district. It is unbelievably reliable to the point that they shoot themselves in the foot on support contracts.

Incentivized

• Proxmox has allowed to us to do more with less. We can invest in a single (or multiple if clustering) host with a decent specification, and run most of our infrastructure on it.
• Open source technologies allowed us to re-use previous skills and knowledge. There was very little onboarding required because we already knew Debian, KVM, ZFS, etc.
• Virtualisation has vastly reduced the amount of time required to maintain all our systems. Everything is so much more organised and lends itself to automation (with Ansible, in our case).

Incentivized

• 0% downtime or loss of revenue due to downtime.
• The simplicity of testing backups in a live environment in the event of a technical catastrophe.
• Ease of mind and a lot less stress worrying about a raid system within a standalone server dying in the middle of the night.
