   7 For production servers, high quality server equipment is needed. Keep
   8 in mind, if you run 10 Virtual Servers on one machine and you then
   9 experience a hardware failure, 10 services are lost. {pve}
  10 supports clustering, this means that multiple {pve} installations
  11 can be centrally managed thanks to the included cluster functionality.
  12
  13 {pve} can use local storage (DAS), SAN, NAS and also distributed
  14 storage (Ceph RBD). For details see xref:chapter_storage[chapter storage].

  16 [[install_minimal_requirements]]
  17 Minimum Requirements, for Evaluation
  18 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  19
  20 * CPU: 64bit (Intel EMT64 or AMD64)
  21
  22 * Intel VT/AMD-V capable CPU/Mainboard for KVM Full Virtualization support
  23
  24 * RAM: 1 GB RAM, plus additional RAM used for guests
  25
  26 * Hard drive
  27
  28 * One NIC

  32 Recommended System Requirements
  33 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  34
  35 * Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag.
  36
  37 * Memory, minimum 2 GB for OS and Proxmox VE services. Plus designated memory
  38   for guests. For Ceph or ZFS additional memory is required, approximately 1 GB
  39   memory for every TB used storage.
  40
  41 * Fast and redundant storage, best results with SSD disks.
  42
  43 * OS storage: Hardware RAID with batteries protected write cache (``BBU'') or
  44   non-RAID with ZFS and SSD cache.
  45
  46 * VM storage: For local storage use a hardware RAID with battery backed
  47   write cache (BBU) or non-RAID for ZFS. Neither ZFS nor Ceph are compatible
  48   with a hardware RAID controller. Shared and distributed storage is also
  49   possible.
  50
  51 * Redundant Gbit NICs, additional NICs depending on the preferred storage
  52   technology and cluster setup – 10 Gbit and higher is also supported.
  53
  54 * For PCI passthrough a CPU with VT-d/AMD-d CPU flag is needed.

  57 Simple Performance Overview
  58 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
  59
  60 On an installed {pve} system, you can run the included `pveperf` script
  61 to obtain an overview of the CPU and hard disk performance.
  62
  63 NOTE: this is just a very quick and general benchmark. More detailed tests
  64 are recommended, especially regarding the I/O performance of your system.
  65
  66 Supported web browsers for accessing the web interface
  67 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  68 To use the web interface you need a modern browser, this includes:
  69
  70 * Firefox, a release from the current year, or the latest Extended
  71 Support Release
  72 * Chrome, a release from the current year
  73 * Microsoft's currently supported versions of Internet Explorer (as
  74 of 2019, this means IE 11 or IE Edge)
  75 * Safari, a release from the current year
  76
  77 If {pve} detects you're connecting from a mobile device, you will be
  78 redirected to a lightweight touch-based UI.
