   7 We recommend using high quality server hardware, when running {pve} in
   8 production. To further decrease the impact of a failed host, you can run {pve} in
   9 a cluster with highly available (HA) virtual machines and containers.
  10
  11 {pve} can use local storage (DAS), SAN, NAS, and distributed storage like Ceph
  12 RBD. For details see xref:chapter_storage[chapter storage].

  15 Minimum Requirements, for Evaluation
  16 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  17
  18 These minimum requirements are for evaluation purposes only and should not be
  19 used in production.
  20
  21 * CPU: 64bit (Intel EMT64 or AMD64)
  22
  23 * Intel VT/AMD-V capable CPU/motherboard for KVM full virtualization support
  24
  25 * RAM: 1 GB RAM, plus additional RAM needed for guests
  26
  27 * Hard drive
  28
  29 * One network card (NIC)
  30

  32 [[install_recommended_requirements]]
  33 Recommended System Requirements
  34 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  35
  36 * Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag.
  37
  38 * Memory: Minimum 2 GB for the OS and {pve} services, plus designated memory for
  39   guests. For Ceph and ZFS, additional memory is required; approximately 1GB of
  40   memory for every TB of used storage.
  41
  42 * Fast and redundant storage, best results are achieved with SSDs.
  43
  44 * OS storage: Use a hardware RAID with battery protected write cache (``BBU'')
  45   or non-RAID with ZFS (optional SSD for ZIL).
  46
  47 * VM storage:
  48 ** For local storage, use either a hardware RAID with battery backed write cache
  49   (BBU) or non-RAID for ZFS and Ceph. Neither ZFS nor Ceph are compatible with a
  50   hardware RAID controller.
  51 ** Shared and distributed storage is possible.
  52 ** SSDs with Power-Loss-Protection (PLP) are recommended for good performance.
  53   Using consumer SSDs is discouraged.
  54
  55 * Redundant (Multi-)Gbit NICs, with additional NICs depending on the preferred
  56   storage technology and cluster setup.
  57
  58 * For PCI(e) passthrough the CPU needs to support the VT-d/AMD-d flag.

  61 Simple Performance Overview
  62 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
  63
  64 To get an overview of the CPU and hard disk performance on an installed {pve}
  65 system, run the included `pveperf` tool.
  66
  67 NOTE: This is just a very quick and general benchmark. More detailed tests are
  68 recommended, especially regarding the I/O performance of your system.
  69
  70 Supported Web Browsers for Accessing the Web Interface
  71 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  72
  73 To access the web-based user interface, we recommend using one of the following
  74 browsers:
  75
  76 * Firefox, a release from the current year, or the latest Extended Support Release
  77 * Chrome, a release from the current year
  78 * Microsoft's currently supported version of Edge
  79 * Safari, a release from the current year
  80
  81 When accessed from a mobile device, {pve} will show a lightweight, touch-based
  82 interface.
