XCP-ng vs Proxmox: My Personal View on Differences

Network Virtualization: A Tale of Two Approaches

From my Proxmox experience in many environments, its networking features stand out for dependability and versatility. Linux bridges are very interesting; I have used them extensively in manufacturing environments where constant performance is vital. One noteworthy project was building a sophisticated multi-VLAN system for a customer in the financial services sector; Proxmox was particularly adept at traffic segmentation, improved by Open vSwitch’s advanced networking capabilities.

On the other hand, XCP-ng uses a different networking approach that I have found very successful in situations requiring great network isolation. For me, the support of SR-IOV has transformed high-performance tasks. Recently, I established a cluster for a research facility where network efficiency was critical; XCP-ng’s near-bare-metal performance via SR-IOV was the perfect answer.

Container Orchestration: The Kubernetes Story

Working with containers in Proxmox has been fascinating. Its built-in LXC support is first-rate for lightweight containerization, but Proxmox shines most with its Kubernetes integration. I recently configured a development environment needing classic VMs and container orchestration, and Proxmox handled this hybrid configuration effortlessly, letting us run Kubernetes clusters next to conventional virtual machines.

XCP-ng presents another but equally successful method of container orchestration. Its Docker integration is strong even if it lacks native LXC capability like Proxmox. On XCP-ng, I have effectively set up many Kubernetes clusters; the platform’s robustness surprised me while managing containerized workloads. Particularly when set up with VLAN isolation, the network performance for container traffic caught attention.

Performance Tuning: The Art of Optimization

Making Proxmox optimal for peak performance has given me a lot of insightful analysis. One important lesson is the need for CPU optimization; observable performance increases have come from matching virtual CPUs with actual CPUs. One project employing a high-performance computer cluster needed this improvement most of all. We obtained near-bare-metal performance for intensive computation activities by exacting CPU pinning and NUMA alignment setup.

Performance tweaking has special qualities in XCP-ng as well. The platform’s memory management—especially its compression features—has helped me optimize performance on hosts with limited memory capacity. I also discovered that XCP-ng has rather good performance optimization for storage. For a storage-intensive task, for example, I performed much more steadily by optimizing IO throttling and storage quality of service settings.

Hardware Compatibility: Real-world Experience

Having used Proxmox several times, I understand the ideal hardware choices. Particularly the most recent models with enhanced virtualizing capability, Intel Xeon CPUs have shown dependability again and again. LSI controllers have done very well in manufacturing settings for storage solutions; Intel NICs are the finest option for networking because of their consistent performance.

Regarding XCP-ng hardware, my experiences have likewise been positive but with some varying ideal solutions. In compute-heavy situations, AMD EPYC CPUs stand out; the speed of enterprise-grade NVMe SSDs for virtual machine storage speaks to me. It was also interesting to learn how Mellanox network cards shine in high-throughput scenarios.

The Price Performance Equation: 2024 Update

Knowing the many price levels on both systems, I can provide some analysis of their economy of cost. Over time, Proxmox’s corporate subscription has evolved; the current cost, which I have found sufficient for many modest to medium-sized installations, starts at $495 annually per node for basic support. Although the premium support option at $1,495 per year per node seems excessive, the benefit of 24/7 help has repeatedly shown itself in crucial settings.

On the other hand, XCP-ng provides a more flexible price schedule, particularly for smaller systems. For companies just starting their virtualizing path, their basic support package of €340 per year makes a good fit. Given its breadth of features and degree of assistance, the premium support at €1,020 per year is especially reasonably cost-effective for bigger installations.

Both platforms have free community versions, and I have successfully operated manufacturing on both. In business environments, however, I often advise choosing a supported version—having access to corporate repositories and the comfort of support may be very important in trying circumstances.

Certain use cases and financial factors determine which Proxmox and XCP-ng to utilize. Drawing on my vast knowledge of both, I can boldly state that any platform can flourish, given the company’s demands and suitable support.
