The Challenge: Physical Servers at Their Limit

A logistics company with 120 employees faced constant IT infrastructure outages. They had 8 physical servers that consumed a lot of energy, required frequent maintenance, and had an average utilization of 20%. Management sought a solution to consolidate servers, improve availability, and reduce operational costs. They evaluated several options and ultimately chose Proxmox VE, an open-source server virtualization platform that promised high availability and centralized management.

Implementation: Migration with Minimal Disruption

The ForgeNEX team designed a 3-node Proxmox cluster with distributed Ceph storage. All virtual machines (VMs) and containers (LXC) were migrated over a weekend using Proxmox's live replication. The process included:

• Inventory of applications and dependencies.
• Creation of standardized templates for Linux and Windows servers.
• Configuration of high availability (HA) for critical services such as ERP and email.
• Integration with automated backups to a local NAS and the cloud.

The migration was completed in 48 hours with only a 2-hour maintenance window. As we mentioned in our article on Business Process Automation with n8n and AI, orchestrating repetitive tasks is key to efficiency, and here Proxmox allowed automating the deployment of new VMs.

Results: Performance, Savings, and Scalability

After six months of operation, the results were compelling:

• 40% reduction in hardware and energy costs: 5 physical servers were eliminated, going from 8 to 3 nodes.
• 99.9% availability: The HA cluster prevented outages even during firmware updates.
• On-demand scalability: New VMs are created in minutes from templates, without the need to provision hardware.
• Ease of management: The IT team can manage everything from a single web panel, reducing administration time by 60%.

Additionally, the company was able to allocate the savings to other digital initiatives, such as improving cybersecurity. In this regard, we recommend reading our case on SAP Under Siege to understand how virtualization also strengthens security by isolating critical applications.

Lessons Learned

This success story demonstrates that virtualization with Proxmox is not only viable for large corporations but also for SMEs looking to optimize their infrastructure. The key was careful planning, training the internal team, and using features such as HA and integrated backups.
