Dell PowerEdge vs. Proxmox VE

An excellent warranty and excellent technical assistance can be expected from the PowerEdge C Series, which comes from a well-known brand with a long track record in the market. Scalability, physical space optimization and performance and dependability for handling sensitive and vital data like databases and ERP systems that are fairly sophisticated are just some of the benefits we get from Dell gear, which saves us resources and energy by up to 40%.

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.

• Good price - Compared to other vendors’ server platforms. In our scenario (virtualization) we found out PowerEdge offers the best price/vCPU and RAM ratio.
• Customizable - We were able to select optimal memory/disk capacity for our use case. Other platform's minimum requirements were above our needs, hence needlessly expensive.
• Good warranty and service - Our project did not involve creating a big cluster with a lot of spare capacity, so the next business day warranty came handy.

• 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.

• The value of 24x7 support is expensive, the value of 8x5NBD is more attractive.
• The other superior models of the C series are more expensive.

• 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.

It is the best server in the market.

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 Dell PowerEdge R range is just intuitive when you have skills engineers managing them in-house, although even with new members of staff on the team, the learning curve is very low providing they have previous general service hardware management experience. From the specification through to the management of this range, the usability is excellent.

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

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

We consider Dell's support to be best-in-class compared to other solutions and is also reasonably priced. Their SLA targets have almost always been met, except for minor occasions that have had extenuating circumstances. The service staff is also professional and thorough. Overall, we are very satisfied with the level of support we receive.

Against hp servers, Dell has outperformed them in terms of incidents regarding hardware memory parts. With the Dell PowerEdge R series servers we have not had any incidents regarding memory modules. On the other hand, with HP servers, we encountered a lot of failures regarding memory modules during the first year of implementation.

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.

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.

• From the perspective of physical server consolidations, when servers spread across multiple branch and remote offices are gathered into a central data center, this simplification process provides ROI in several ways. One, the configuration control, restriction of server access.
• Reduce complexity and enable greater standardization of hardware purchases, which lowers costs.
• Increased security of the move are important.
• The costs of moves, add-ins, and changes are reduced, as well as the costs of travel time and maintenance.
• Migrating legacy operating systems to a newer version via rehosting brings similar ROI benefits when it comes to server consolidation.

• 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.
