-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].
+We recommend using high quality server hardware, when running {pve} in
+production. To further decrease the impact of a failed host, you can run {pve} in
+a cluster with highly available (HA) virtual machines and containers.
+{pve} can use local storage (DAS), SAN, NAS, and distributed storage like Ceph
+RBD. For details see xref:chapter_storage[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/Mainboard for KVM Full Virtualization support
+* Intel VT/AMD-V capable CPU/Mainboard for KVM full virtualization support
-* RAM: 1 GB RAM, plus additional RAM used for guests
+* RAM: 1 GB RAM, plus additional RAM needed for guests
* Hard drive
-* One NIC
+* One network card (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 the OS and {pve} services, plus designated memory for
+ guests. For Ceph and ZFS, additional memory is required; approximately 1GB of
+ memory for every TB of used storage.
-* RAM: 8 GB RAM, plus additional RAM used for guests
+* Fast and redundant storage, best results are achieved with SSDs.
-* Hardware RAID with batteries protected write cache (``BBU'') or flash
- based protection
+* OS storage: Use a hardware RAID with battery protected write cache (``BBU'')
+ or non-RAID with ZFS (optional SSD for ZIL).
-* Fast hard drives, best results with 15k rpm SAS, Raid10
+* 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.
-* At least two NICs, depending on the used storage technology you need more
+* 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
~~~~~~~~~~~~~~~~~~~~~~~~~~~
-On an installed {pve} system, you can run the included `pveperf` script
-to obtain an overview of the CPU and hard disk performance.
+To get an overview of the CPU and hard disk performance on an installed {pve}
+system, run the included `pveperf` tool.
-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
+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
+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
-* 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 version of Edge
+* Safari, a release from the current year
-If {pve} detects you're connecting from a mobile device, you will be
-redirected to a lightweight touch-based UI.
+When accessed from a mobile device, {pve} will show a lightweight, touch-based
+interface.
