System Requirements

We recommend using high quality server hardware, when running Proxmox VE in production. To further decrease the impact of a failed host, you can run Proxmox VE in a cluster with highly available (HA) virtual machines and containers.

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

Minimum Requirements, for Evaluation

These minimum requirements are for evaluation purposes only and should not be used in production.

• CPU: 64bit (Intel EMT64 or AMD64)

• Intel VT/AMD-V capable CPU/motherboard for KVM full virtualization support

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

• Hard drive

• One network card (NIC)

Recommended System Requirements

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

• Memory: Minimum 2 GB for the OS and Proxmox VE services, plus designated memory for guests. For Ceph and ZFS, additional memory is required; approximately 1GB of memory for every TB of used storage.

• Fast and redundant storage, best results are achieved with SSDs.

• OS storage: Use a hardware RAID with battery protected write cache (“BBU”) or non-RAID with ZFS (optional SSD for ZIL).

• VM storage:

  • For local storage, use either a hardware RAID with battery backed write cache (BBU) or non-RAID for ZFS and Ceph. Neither ZFS nor Ceph are compatible with a hardware RAID controller.

  • Shared and distributed storage is possible.

  • SSDs with Power-Loss-Protection (PLP) are recommended for good performance. Using consumer SSDs is discouraged.

• Redundant (Multi-)Gbit NICs, with additional NICs depending on the preferred storage technology and cluster setup.

• For PCI(e) passthrough the CPU needs to support the VT-d/AMD-d flag.

Simple Performance Overview

To get an overview of the CPU and hard disk performance on an installed Proxmox VE system, run the included pveperf tool.

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 access the web-based user interface, we recommend using one of the following browsers:

• Firefox, a release from the current year, or the latest Extended Support Release

• Chrome, a release from the current year

• Microsoft’s currently supported version of Edge

• Safari, a release from the current year

When accessed from a mobile device, Proxmox VE will show a lightweight, touch-based interface.
