The following are trademarks of their respective owners: Proxmox VE (Proxmox Server Solutions GmbH). WZ-IT is an independent service provider and has no business, partnership, or contractual relationship with these companies. We offer independent migration, installation, hosting, and operations services.

Setup Options

Three setup variants - matching your workload

From simple single-node to hyperconverged Ceph cluster.

Single-Node Setup

One server, one PVE installation. Ideal for smaller workloads, dev/staging or as entry point.

  • Hardware setup & ZFS configuration
  • Network and firewall configuration
  • Backup strategy (PBS or Hetzner Storage Box)
  • Monitoring integration

HA Cluster (3+ Nodes)

High availability cluster with quorum. Automatic failover, live migration, no single point of failure.

  • Minimum 3 nodes for quorum
  • Corosync on separate network
  • HA Rules instead of HA Groups (PVE 9)
  • Live migration between nodes

Hyperconverged with Ceph

Compute and storage on the same nodes. Ceph replicates across all nodes - no external SAN needed.

  • Ceph Squid 19.2 (PVE 9)
  • Replication factor 3 for full redundancy
  • NVMe recommended for OSD performance
  • Erasure coding optional
6-Step Process

From hardware to production-ready infrastructure

Structured process with clear milestones - typically 3-10 working days for a complete setup.

01

Hardware Preparation

BIOS/UEFI setup, IPMI configuration, disk layout. With Hetzner Dedicated: auto-install script. With own hardware: Proxmox ISO boot.

02

Proxmox VE 9 Installation

Installation with ZFS RAID-1/10 or LVM. Remove subscription notice, configure repositories, first updates.

03

Network & Storage

Bridge configuration, VLAN tagging, cluster network. Set up storage backend (Ceph, NFS, iSCSI) and define pools.

04

Cluster Setup

pvecm create on master node, join additional nodes, verify cluster quorum. Activate HA configuration.

05

Backup & Monitoring

Integrate PBS, define backup jobs (3-2-1 rule), monitoring with Grafana/Prometheus. First test restores.

06

Handover & Documentation

Complete documentation of configuration, runbooks for standard operations, optional training for your team.

Where should your Proxmox run?

Provider-specific setup guides

Each provider has its own quirks - network, storage, IPMI. We know them all.

The production baseline: what we insist on during setup

Anyone can install Proxmox in an hour. A setup that is still maintainable three years later comes from the decisions made beforehand. Our baseline follows the official Proxmox documentation recommendations - and the experience from taken-over environments where exactly this was skipped:

Enterprise SSDs with PLP

The Proxmox docs explicitly discourage consumer SSDs: without power-loss protection, sync writes (ZFS, Ceph, databases) collapse dramatically, and data loss looms on power failure.

ECC RAM for ZFS

For ZFS, the official documentation recommends high-quality ECC memory - otherwise RAM bit errors silently end up in your data. Plus: enough RAM for the ARC (base 2 GiB + 1 GiB per TiB of storage).

Mirrors instead of RAIDZ for VMs

For VM workloads, IOPS is what counts. Mirror vdevs (RAID1/RAID10) are the right choice per the docs; RAIDZ costs zvol performance and surprisingly much space through parity and volblocksize.

HBA instead of hardware RAID

ZFS and Ceph want to see the disks directly. Hardware RAID controllers underneath are one of the most common causes of creeping storage problems - we use HBA/IT mode.

Dedicated corosync network

The cluster heartbeat needs latencies under 5 ms and tolerates no competition from storage or migration traffic. With us, corosync gets its own NIC - plus redundant links (up to 8 supported).

Backups from day one

PBS with verify jobs and an offsite copy is part of the setup, not a retrofit. A cluster without a tested restore is not production-ready - no matter how good the rest is.

The five mistakes we find most often in takeovers

We regularly take over self-built Proxmox environments into operation - and keep seeing the same patterns. None of these mistakes show on day one. All of them get expensive when the first emergency arrives:

  • Consumer SSDs without PLP - the cluster becomes inexplicably slow after months
  • Corosync sharing the network with storage - the cluster self-fences under load
  • RAIDZ under VM workloads - an IOPS bottleneck only fixable by rebuilding
  • Backups on the same host or never tested - worthless in an emergency
  • No documentation - the setup lives in one person's head

Already built it yourself?

If your environment is already running and some of these points sound familiar: a health check uncovers the risks in a structured way, after which we optionally take over stabilization and operations - without a rebuild.

Proxmox takeover
Enquiry

Plan a Proxmox deployment

Name hardware, workloads, and requirements for storage, networking, and availability.

Where should we start?

Choose the appropriate starting point and add the technical context.

How should we get back to you?

We usually respond within one business day. Please do not submit credentials.

We build new environments on the current Proxmox VE 9.x (Debian 13) - as of July 2026 that is PVE 9.2. Important for existing environments: Proxmox VE 8 reaches end of life in August 2026. Anyone setting up or migrating now starts directly on the 9.x line and skips the upgrade.

A single-node setup is productive in 1-2 working days. A 3-node HA cluster with Ceph typically takes 5-10 working days - depending on hardware availability, network complexity and data volume for the initial migration.

Single-node setup from €1,500 (fixed price). 3-node HA cluster from €6,500. Hyperconverged with Ceph from €9,500. Hardware on top - we can either use your hardware or procure from Hetzner/Thomas-Krenn/Dell. After an initial call we give a binding fixed price.

With cloud/hosting providers (Hetzner, OVH, IONOS) everything is possible remotely. With on-premise setups a 1-day on-site appointment for hardware connection and IPMI setup is usually needed - after that everything runs remote.

For Hetzner: AX/EX line with AMD EPYC or Intel Xeon, at least 64 GB RAM, NVMe storage. For on-premise: Thomas-Krenn, Dell PowerEdge or Supermicro with IPMI/iDRAC. We validate the configuration before purchase - no margin on hardware sales.

You have three options: (1) Self-operate with our documentation, (2) Managed Service with 24/7 monitoring and a selectable service level, or (3) an hourly retainer for occasional support. You are never locked in.

Yes. We optionally offer admin training (4-8 hours) for your team - from Proxmox basics to Ceph operations. On request we also write runbooks for standard operations like VM provisioning, backup restore or node reboots.

WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.

I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us.

Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.
