Which Proxmox version does WZ-IT deploy?

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

How long does a Proxmox setup take?

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. Delivery ranges start once scope and remote access are confirmed.

How much does Proxmox installation cost?

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.

Does WZ-IT need to be on site for the installation?

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.

What hardware is required?

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.

Is Ceph included in the three-node cluster 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.

What happens after the technical handover?

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 packages and more extensive runbooks can also be agreed separately.

Can Proxmox be used for free?

Yes. Proxmox VE is open source and usable without licence fees. An optional subscription provides the enterprise repository and vendor support from Basic upwards. It is not included in the setup price and is available through WZ-IT as an Authorized Reseller of Proxmox Server Solutions GmbH.

Does ZFS make sense for Proxmox?

ZFS can be suitable with appropriate directly attached disks. RAM, redundancy, capacity and IOPS are assessed against the workloads. The guide ZFS, Ceph and LVM compared explains the choice.

Have Proxmox installed: single node to three-node cluster

WZ-IT installs new Proxmox VE systems on your existing or rented hardware. The agreed storage and network setup, backup integration, functional testing, documentation and technical handover are included.

From takeovers

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

Process

Proxmox setup in five steps: scope, installation, networking, backup, 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.

01
Scope and prerequisites
Hardware, remote access, networking, storage, backup destination and the required target topology are confirmed before the implementation date. A subscription can be obtained separately through WZ-IT as an Authorized Reseller.
02
Installation and hardening
Proxmox VE is installed and updated with the agreed repositories, administrative access paths and baseline safeguards.
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.
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.
05
Documentation and handover
You receive the documented configuration and a technical handover. Managed Proxmox or ad hoc support can be commissioned separately afterwards.

Result

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
For good performance, Proxmox recommends SSDs with power-loss protection (PLP) and discourages consumer SSDs. Without PLP, sync writes (ZFS, Ceph, databases) drop sharply (system requirements).
ECC RAM for ZFS
For ZFS, the documentation recommends high-quality ECC RAM to prevent data corruption. As a rule of thumb, allocate at least 2 GiB plus 1 GiB per TiB of storage for the ARC (ZFS chapter).
Mirrors instead of RAIDZ for VMs
For VM workloads, IOPS is what counts. Mirror vdevs give the best performance characteristics, a RAIDZ behaves roughly like a single disk for IOPS, and zvols add space overhead through parity and volblocksize (ZFS RAID considerations).
HBA instead of hardware RAID
ZFS and Ceph need direct access to the disks and, per the documentation, are not compatible with hardware RAID controllers. We use HBAs or controllers in IT mode (system requirements).
Dedicated corosync network
The cluster heartbeat needs latencies under 5 ms, and corosync ideally runs on its own physically separated network instead of sharing it with storage. With us, corosync gets its own NIC, plus redundant links (up to eight supported) (cluster network).
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.

Networking & Provisioning

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.
