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. {pve}
supports clustering, this means that multiple {pve} installations
can be centrally managed thanks to the included cluster functionality.
{pve} can use local storage (DAS), SAN, NAS and also distributed

storage (Ceph RBD). For details see xref:chapter_storage[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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2019-02-25 10:51:06 +01:00
* Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag.
2016-10-05 10:24:51 +02:00
2019-02-25 10:51:06 +01:00
* 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.
2016-10-05 10:24:51 +02:00
2019-02-25 10:51:06 +01:00
* OS storage: Hardware RAID with batteries protected write cache (``BBU'') or
non-RAID with ZFS and SSD cache.
2016-10-05 10:24:51 +02:00
2019-02-25 10:51:06 +01:00
* 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.

2019-02-25 10:51:06 +01:00
* Redundant Gbit NICs, additional NICs depending on the preferred storage
technology and cluster setup –

2019-02-25 10:51:06 +01:00
* For PCI passthrough a CPU with VT-d/AMD-d CPU flag is needed.

Simple Performance Overview
~~~~~~~~~~~~~~~~~~~~~~~~~~~
On an installed {pve} 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.
2016-10-05 13:16:29 +02:00
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
2019-09-04 09:00:02 +02:00
* Microsofts currently supported version of Edge
2019-02-25 12:23:53 +01:00
* Safari, a release from the current year
2016-10-05 13:16:29 +02:00
If {pve} detects you're connecting from a mobile device, you will be
redirected to a lightweight touch-based UI.
