What Proxmox VE brings to your infrastructure

Proxmox VE integrates in a single platform everything that previously required vSphere + vCenter + vSAN + NSX from VMware.

High Availability (HA)

Automatic VM restart on node failure. 3-node quorum. STONITH fencing. VMware HA equivalent — without the licence premium.

🔄

Live migration

Move VMs between nodes without service interruption — equivalent to VMware vMotion. Ideal for planned hardware maintenance.

💾

Snapshots & Replication

Instant ZFS/Ceph snapshots. Async replication to DR site. VM restore in seconds. Integrated with Proxmox Backup Server.

🗄️

Ceph distributed storage

Native Ceph cluster in Proxmox VE — replaces a 30,000+ TND SAN. 3x replication, automatic self-healing, scalable without downtime.

🖥️

KVM + LXC

KVM VMs for Windows Server, SQL Server, Exchange. LXC containers for Linux workloads (Nginx, PostgreSQL, Redis) — near-native performance, maximum density.

🌐

Built-in SDN & VLAN

Virtual router, VLANs, per-VM firewall, VRF, VXLAN. Software-defined networking without additional hardware. Native OPNsense integration.

Proxmox VE vs VMware vSphere — 2026 Comparison

Since Broadcom's acquisition of VMware (2023), licences have increased 300–1000%. Proxmox VE delivers the same enterprise features without vendor lock-in.

💰

Licence cost

VMware : vSphere Foundation ≈ 6 000 USD/an par socket (Broadcom 2024). Proxmox : 0€ (open source) + support optionnel à partir de 119€/an par nœud.

VMware: vSphere Foundation ≈ $6,000/year per socket (Broadcom 2024). Proxmox: €0 (open source) + optional support from €119/year per node.

Our VMware → Proxmox migration approach

Risk-free migration: your VMware infrastructure remains operational until full Proxmox production validation.

1️⃣

Audit & mapping

Inventory of existing VMs, network dependencies, storage, application licences. Documented migration plan with switchover order and rollback plan.

2️⃣

Proxmox cluster deployment

Proxmox VE installation on physical servers (or alongside VMware). VLAN network config, Ceph or NFS storage, LDAP/AD auth, TLS certificates.

3️⃣

Phased migration & validation

VMDK→qcow2 conversion via `qemu-img`. VM-by-VM switchover. Full application testing before each switch. VMware kept in parallel until final validation.

Frequently Asked Questions

Does Proxmox VE truly replace VMware vSphere?

Yes for 95% of use cases. Proxmox covers HA, live migration, snapshots, replication, SDN, Ceph distributed storage. The main gap is the absence of a direct vSphere Distributed Switch equivalent — compensated by OPNsense integration.

What does a VMware → Proxmox migration cost?

For a 3–10 node cluster: 3–10 integration days. Convergent provides a documented plan, pre-switchover test validation, and post-migration support. VMware licence savings are typically recovered in under one year.

Does Proxmox support Windows Server and SQL Server?

Yes. Proxmox VE virtualises Windows Server 2012 R2 to 2025, SQL Server, Active Directory, Exchange. VirtIO drivers deliver near-bare-metal performance. Windows licences remain unchanged.

What is the minimum configuration for an HA cluster?

Minimum 3 nodes for Proxmox quorum (avoids split-brain). Each node: x86-64 CPU with VT-x/AMD-V, minimum 32 GB RAM, SSD storage for critical VMs. Dedicated network recommended for Ceph/replication traffic (1–10 Gbps).
