Scope and pricing

Two defined starting points for new Proxmox environments

The single node has a fixed remote standard scope. For the three-node cluster, the final price is confirmed after reviewing hardware, networking and storage.

One host

Single Node Setup

For a new Proxmox host with local storage, defined network paths and external backup integration.

from€1,490 one-time

Excl. VAT, one-time, for the stated remote standard scope. Hardware and the Proxmox subscription are not included.

  • One compatible physical server with working remote management
  • One local storage layout using a ZFS mirror or LVM-thin
  • Management and workload bridge plus a firewall baseline
  • Functional test using one test VM

Three hosts

Three-node Cluster Setup

For a new Proxmox cluster with quorum, a separate Corosync path and an agreed HA and storage model.

from€4,990 one-time

Excl. VAT, one-time, from the stated price. The binding price follows the hardware, network and storage review.

  • Three compatible nodes and implementation of the Proxmox cluster
  • Quorum and Corosync over the agreed network path
  • One agreed storage path, such as ZFS replication or existing shared storage
  • HA rules plus migration and failover testing with a test workload

All plans include

  • Review of hardware compatibility, target topology and prerequisites before the scheduled work
  • Current stable Proxmox VE version, repositories, updates and technical baseline hardening
  • Connection of one existing external backup destination and validation of a test job
  • Configuration documentation and technical handover

Ceph, migration or specialist infrastructure?

Ceph/HCI, implementation of a Proxmox Backup Server, production workload migrations, specialist routing and firewall requirements, multiple sites, and on-site work in the DACH region are planned and quoted separately.

Process

From technical scope to documented handover

Once the prerequisites are clear, delivery takes place remotely or, where the project requires it, with an on-site component in the DACH region.

  1. 01

    Scope and prerequisites

    Hardware, remote access, networking, storage, backup destination and the required target topology are confirmed before the implementation date.

  2. 02

    Installation and hardening

    Proxmox VE is installed and updated with the agreed repositories, administrative access paths and baseline safeguards.

  3. 03

    Networking and storage

    Bridges, VLANs and storage are implemented within the agreed standard scope. For a cluster, Corosync, quorum and the HA storage path are added.

  4. 04

    Backup and functional testing

    An existing backup destination is connected. Installation, networking and storage are validated with test workloads; a cluster also receives migration and failover tests.

  5. 05

    Documentation and handover

    You receive the documented configuration and a technical handover. Managed Proxmox or ad hoc support can be commissioned separately afterwards.

Deployment location

On your own hardware or dedicated servers

Networking, remote console and storage differ by provider. The available resources are therefore reviewed against the selected standard scope before setup.

Technical baseline for maintainable operations

An installation alone does not define a robust virtualisation platform. Maintainability primarily depends on hardware, storage, networking and backup decisions, so these points are reviewed for every new deployment.

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).

External backup path

The standard setup connects one existing external backup destination and validates a test job. PBS implementation, off-site copies and isolated restore tests remain separately commissioned services.

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

For professional secrecy holders

Operate Proxmox in the Section 203 Managed Cloud

If Proxmox processes client, patient or other professional secrets, WZ-IT plans the application, infrastructure, access, backups and ongoing operations within a purpose-built operating model.

Frequently Asked Questions

Answers to the most important questions

New environments are built on the current stable Proxmox VE 9 release available at the implementation date. Proxmox VE 8 reached end of life in August 2026, so for existing environments we first assess the required upgrade or migration path.

A single node within the approved remote standard scope generally takes one to two working days. A three-node cluster typically takes three to seven working days. Hardware procurement and production workload migrations are not included in these timeframes.

The Single Node Setup starts at €1,490 excl. VAT one-time. The Three-node Cluster Setup starts at €4,990 excl. VAT one-time. Hardware, the Proxmox subscription, production migrations and separately agreed extensions are added where required.

With a working remote console and prepared network access, setup can be completed entirely remotely. Where rack installation, cabling or local coordination is required, on-site delivery in Germany and the DACH region is also available depending on the project. Travel and on-site services are stated separately.

Before the scheduled work, we assess CPU, memory, drives, controllers, network interfaces and remote management against the planned workloads. Suitable enterprise drives, power-loss protection and an appropriate network topology are particularly relevant for ZFS and Ceph. Hardware and vendor subscriptions are not included in the installation price.

No. The starting price covers a three-node cluster with one agreed standard storage path. A hyperconverged Ceph cluster requires a separate review of OSDs, failure domains, capacity, networking and recovery requirements and is therefore quoted individually.

You can operate the documented environment yourself or commission Managed Proxmox separately with proactive 24/7 monitoring, updates, backup management and a selectable service level. Production and Critical add round-the-clock P1 response. Training, hour allowances and more extensive runbooks can also be agreed separately.

“WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.”
