Let us simplify your purchasing journey. If your organization requires coordinated
procurement, custom subscription planning, or assistance with internal approvals, our
specialists are ready to guide you toward the most effective infrastructure strategy.
Expert support is a core infrastructure requirement
For infrastructure that carries critical services, qualified product support is part of the
control environment. Internal policy, customer commitments, external audit criteria, and sector
or government regulation can require a documented vendor escalation path, tested updates, and
demonstrable software supply-chain resilience.
Operational stability
Standardize production systems on a stable package stream with extensively tested updates and
security enhancements.
Expert escalation path
Give your infrastructure team a direct route to Proxmox specialists when critical issues
require deeper product expertise.
Predictable annual coverage
Plan subscription costs by CPU socket with no separate feature editions or per-core
licensing complexity.
For non-production use
Community subscription
Running Proxmox VE in a home lab, technical learning environment, or professional test setup?
Community gives you access to the stable Enterprise Repository without an enterprise technical
support entitlement.
Home labsProfessional home

clustersNon-critical workloads
Need support for production workloads? Choose Basic, Standard, or Premium
above for access to Proxmox technical support.
COMMUNITY
Stable updates for independent and non-enterprise environments
A subscription is required for every occupied physical CPU socket. The number of CPU cores
does not affect the price. Every server in a cluster needs coverage for its occupied
sockets, and all nodes in a cluster must use the same subscription level.
Are Proxmox VE features limited by subscription level?
No. High availability, live migration, clustering, backup, software-defined storage,
networking, and all other Proxmox VE features are available at every level. Plans differ by
technical support entitlement, ticket allowance, and response time.
What does “response time” mean?
It is the guaranteed first response time for a critical support request submitted through the
Proxmox Customer Portal. Coverage applies within the business hours defined in the
subscription agreement.
Can my organization purchase without using the Online Shop?
Contact sales at sales@proxmox.com to discuss your purchasing requirements. Qualified Proxmox
resellers can also provide local purchasing, consulting, implementation, and support
services.
What support is included with Community?
Community includes access to the Enterprise Repository but not ticket support from the
Proxmox enterprise support team. Assistance is available through the public Proxmox
community forum.
What are the enterprise support business hours?
Ticket support for Basic, Standard, and Premium is available Monday through Friday,
07:00–17:00 CET/CEST on Austrian business days. Qualified resellers may offer support in
other time zones and local languages. Please contact sales@proxmox.com if you have requirements beyond the standard offerings.

I recommend Proxmox for those IT professionals who want to increase the availability of their servers, to reduce the administration complexity and also to make the most of their IT budget...Valentín Ortiz Ferretiz Read more >
For production servers, high quality server equipment is needed. Proxmox VE supports clustering, this means that multiple Proxmox VE installations can be centrally managed thanks to the integrated cluster functionality. Proxmox VE can use local storage like (DAS), SAN, NAS, as well as shared, and distributed storage (Ceph).
Recommended Hardware
Intel 64 or AMD64 with Intel VT or AMD-V CPU flag. Alternatively, 64-bit Arm (Armv9-A or newer processor).
Memory, minimum 2 GB for OS and Proxmox VE services. Plus designated memory for guests. For Ceph or ZFS additional memory is required, approximately 1 GB memory for every TB used storage.
Fast and redundant storage, best results with SSD disks.
OS storage: Hardware RAID with batteries protected write cache (“BBU”) or non-RAID with ZFS and SSD cache.
VM storage: For local storage use a hardware RAID with battery backed write cache (BBU) or non-RAID for ZFS. Neither ZFS nor Ceph are compatible with a hardware RAID controller. Shared and distributed storage is also possible.
Redundant Gbit NICs, additional NICs depending on the preferred storage technology and cluster setup – 10 Gbit and higher is also supported.
For PCI(e) passthrough a CPU with VT-d or AMD-Vi CPU flag is required.
For Evaluation
Minimum Hardware (for testing only)
CPU: 64bit (Intel 64 or AMD64). Alternatively, 64-bit Arm (Armv9-A or newer processor).
For x86 hosts: Intel VT or AMD-V capable CPU and motherboard (required for x86 KVM full virtualization support).
Proxmox VE can be installed as a guest on all common used desktop virtualization solutions as long as they support nested virtualization.
Supported web browsers for accessing the web interface
To use the web interface you need a modern browser, this includes:
Firefox, a release from the current year, or the latest Extended Support Release
Chrome, a release from the current year
Microsofts currently supported version of Edge
Safari, a release from the current year
Installation on a Debian system
If you want you can install Proxmox VE on top of a running Debian 64-bit. This is especially interesting, if you want to have a custom partition layout.
