System Requirements ------------------- ifdef::wiki[] :pve-toplevel: endif::wiki[] 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 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * CPU: 64bit (Intel EMT64 or AMD64), Multi core CPU recommended * Intel VT/AMD-V capable CPU/Mainboard for KVM Full Virtualization support * RAM: 8 GB RAM, plus additional RAM used for guests * Hardware RAID with batteries protected write cache (``BBU'') or flash based protection * Fast hard drives, best results with 15k rpm SAS, Raid10 * At least two NICs, depending on the used storage technology you need more 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. 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 * 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) If {pve} detects you're connecting from a mobile device, you will be redirected to a lightweight touch-based UI.
