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.

Scale is best suited to environments that do not have excessive external or proprietary peripherals. Integrating with tape drive backups or robot tape libraries can be problematic. The most effective use of Scale systems is for companies running multiple instances of the same operating system. The hypervisor's code/file-sharing nature does an excellent job managing new instances while keeping the increase in storage to a minimum.

• 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.

• Simplicity - I do not have to create storage buckets or micromanage anything.
• Efficiency - Lower power use since moving to a hyperconverged environment.
• Scalability - Adding additional hardware is easy, and increasing things like the amount of RAM or number of cores is easy.

• 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.

• Dedicated Lights-Out Solution for low-end systems
• Ability to replace smaller storage drives with larger ones, rather than requiring the addition of an entire node for storage increases
• Different UI views for VMs: ability to minimize certain groups and have that persist through log-ins

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.

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

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.

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 very knowledgeable about their own products and hardware addressing my concerns or issues very quickly and on the first contact. Calls concerning VMware migrations and Acronis backup took a little more time for more complicated issues, but the Scale Computing Platform techs were diligent to stay on top of issues until they were resolved. Most of my issues have been with the initial setup/migration.

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 previously used Microsoft Hyper V and VMWare and, before that, a room for single-purpose servers. My satisfaction with Scale is because it is a more straightforward product to install and use; it has incredible speed and reliability. In the past, getting support from Microsoft was labor intensive, and with VMWare, there was a language accent barrier.

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.

• With the high cost of the leading competitor the savings starts day one and saves every year after.
• Scale can be administered by a tier one technician so cost of labor is reduced.
• If there is a problem like a cyber attack, the savings kick in with the least amount of downtime.
