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]. [[install_minimal_requirements]] 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 [[install_recommended_requirements]] Recommended System Requirements ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag. * 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. 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 * 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 If {pve} detects you're connecting from a mobile device, you will be redirected to a lightweight touch-based UI.
