For production servers, high quality server equipment is needed. Keep
in mind, if you run 10 Virtual Servers on one machine and you then
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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* One NIC
+[[install_recommended_requirements]]
Recommended System Requirements
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-* CPU: 64bit (Intel EMT64 or AMD64), Multi core CPU recommended
+* Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag.
-* Intel VT/AMD-V capable CPU/Mainboard for KVM Full Virtualization support
+* 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.
-* RAM: 8 GB RAM, plus additional RAM used for guests
-* Hardware RAID with batteries protected write cache (``BBU'') or flash
- based protection
+Simple Performance Overview
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
-* Fast hard drives, best results with 15k rpm SAS, Raid10
+On an installed {pve} system, you can run the included `pveperf` script
+to obtain an overview of the CPU and hard disk performance.
-* At least two NICs, depending on the used storage technology you need more
+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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Firefox, a release from the current year, or the latest Extended
Support Release
* Chrome, a release from the current year
-* the Microsoft currently supported versions of Internet Explorer (as
-of 2016, this means IE 11 or IE Edge)
-* the Apple currently supported versions of Safari (as of 2016, this
-means Safari 9)
+* 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
