Proxmox VE vs. SUSE Linux Enterprise Server

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.

We use it for every linux service we need to have running. It really works great and is easily manageable with the SUSE Manager, which helps a lot with the updating process. Although it is not stressfull on the CMD itself, it really does simplify things. Besides that, we are really happy with working with SUSE Linux Enterprise Server.

• 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.

• Consistently performs well across various CPU architectures.
• It's very well supported both by the parent company, as well as SAP and other third-party companies.
• It is upgradeable across versions. We've performed upgrades from version 10 to 11 and from 11 to 12 without any major issues.

• The web UI does not work as well on mobile devices. It is useable, but a mobile optimised / responsive UI would be nice to have. There is a mobile app, so that may alleviate this issue, but I have not yet tried it.
• Support in the community forums could be better. There are paid support plans, but new users trying out the software will not have access to this. Answers to questions can sometimes be terse, and I can imagine this may put some people off.
• The wiki is a bit hit and miss with certain topics. I've often seen outdated or missing information, and the whole thing looks like it could do with some polish. I'd love to see it opened up for the community to add to.

Incentivized

• The support window for service packs after a new SP is released is too short.
• Community engagement is low.
• There are times when supported packages fall too far behind and create compatibility issues with applications. The Open Build Service usually provides a way around this, though.

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.

The interface is easy to use for most of it, but still lacks screens for some configurations. Also, a few of the screens are not as intuitive as they could be. This is specially true with disk and network configuration, where some graphic/visual representations of the configurations would be very useful

We've been using this OS for about 8 years in a productive environment. During this time, we have never run into any problems that stopped or impacted our production environment. We have been able to solve any problem we ran into using either common sense, suse documentation or suse support.

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.

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

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

Support personnel are helpful and fairly fast to bring resolution to non-emergency issues. Patches are created and posted in a timely fashion. We so far have not had any major problems that needed support

Third party training was fast but mostly unnecessary as we were already Unix trained and Linux familiar

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

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.

We went straight to SLES when we initially started migrating oracle to hana since at that time, HANA came on a pre-installed server that had to be purchased from an official vendor, and SLES was the only allowed OS. We stuck with SLES after we became certified to do our own installations because so far, SLES was a good fit for us.

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.

We have successfully deployed on physical servers, VMs and in cloud all over the globe from templates of our own design

• Due to the open source nature of Proxmox, we have no licensing costs while training our employees
• We've migrated 100% of our clients to Proxmox and have found improved uptime, and flexibility.
• In the 10 years of using Proxmox, we've yet to lose any data or not be notified of backup issues.

• Compared to others, use is more stable and scalable; easy to manage.
• The administration tools are very useful in helping the staff performance.
• SLES proved to be a very extendable product, supporting all of our infrastructure.
• The major reason I chose to use the product was the extensive enterprise peripheral support.
