-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.
+We recommend to use 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 also distributed
-storage (Ceph RBD). For details see xref:chapter_storage[chapter storage].

 Minimum Requirements, for Evaluation
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 * Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag.
 
-* Memory, minimum 2 GB for OS and Proxmox VE services. Plus designated memory

-  non-RAID with ZFS and SSD cache.
+* OS storage: Use a hardware RAID with battery protected write cache (``BBU'')

-* VM storage: For local storage use a hardware RAID with battery backed

-  possible.

 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
-* Microsofts currently supported version of Edge
-* Safari, a release from the current year
+To access the web-based user interface one of the following browsers is
+recommended:

+* Chrome, a release of the current year
+* Microsoft's currently supported version of Edge
+* Safari, a release of the current year
 
-If {pve} detects you're connecting from a mobile device, you will be
-redirected to a lightweight touch-based UI.
