System Requirements: Difference between revisions

Revision as of 08:04, 16 April 2019

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.

+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
+Recommended System Requirements
+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 (&#8220;BBU&#8221;) 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 â 10 Gbit and higher is also supported.
+For PCI passthrough a CPU with VT-d/AMD-d CPU flag is needed.

+Supported web browsers for accessing the web interface
+To use the web interface you need a modern browser, this includes:

+Support Release
+Chrome, a release from the current year
+Microsoft&#8217;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&#8217;re connecting from a mobile device, you will be
+redirected to a lightweight touch-based UI.
