System Requirements

For production servers, high quality server equipment is needed. Keep in mind, if you run 10 Virtual Servers on one machine and you then experience a hardware failure, 10 services are lost. Proxmox VE supports clustering, this means that multiple Proxmox VE installations can be centrally managed thanks to the included cluster functionality.

Proxmox VE can use local storage (DAS), SAN, NAS and also distributed storage (Ceph RBD). For details see chapter storage.

Minimum Requirements, for Evaluation

  • CPU: 64bit (Intel EMT64 or AMD64)

  • Intel VT/AMD-V capable CPU/Mainboard for KVM Full Virtualization support

  • RAM: 1 GB RAM, plus additional RAM used for guests

  • Hard drive

  • One NIC

  • Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag.

  • 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 passthrough a CPU with VT-d/AMD-d CPU flag is needed.

Simple Performance Overview

On an installed Proxmox VE system, you can run the included pveperf script to obtain an overview of the CPU and hard disk performance.

Note this is just a very quick and general benchmark. More detailed tests are recommended, especially regarding the I/O performance of your system.

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

  • Microsoft’s currently supported versions of Internet Explorer (as of 2019, this means IE 11 or IE Edge)

  • Safari, a release from the current year

If Proxmox VE detects you’re connecting from a mobile device, you will be redirected to a lightweight touch-based UI.
