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 64 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 64 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.
