7 We recommend to use 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.
11 {pve} can use local storage (DAS), SAN, NAS, and distributed storage like Ceph
12 RBD. For details see xref:chapter_storage[chapter storage].
14 [[install_minimal_requirements]]
15 Minimum Requirements, for Evaluation
16 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
18 These minimum requirements are for evaluation purposes only and should not be
21 * CPU: 64bit (Intel EMT64 or AMD64)
23 * Intel VT/AMD-V capable CPU/Mainboard for KVM full virtualization support
25 * RAM: 1 GB RAM, plus additional RAM used for guests
32 [[install_recommended_requirements]]
33 Recommended System Requirements
34 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
36 * Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag.
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.
42 * Fast and redundant storage, best results are achieved with SSDs.
44 * OS storage: Use a hardware RAID with battery protected write cache (``BBU'')
45 or non-RAID with ZFS (optional SSD for ZIL).
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.
53 * Redundant (Multi-)Gbit NICs with additional NICs depending on the preferred
54 storage technology and cluster setup.
56 * For PCI(e) passthrough the CPU needs to support the VT-d/AMD-d flag.
59 Simple Performance Overview
60 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
62 To get an overview of the CPU and hard disk performance on an installed {pve}
63 system, run the included `pveperf` tool.
65 NOTE: This is just a very quick and general benchmark. More detailed tests are
66 recommended, especially regarding the I/O performance of your system.
68 Supported Web Browsers for Accessing the Web Interface
69 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
71 To access the web-based user interface one of the following browsers is
74 * Firefox, a release of the current year, or the latest Extended Support Release
75 * Chrome, a release of the current year
76 * Microsoft's currently supported version of Edge
77 * Safari, a release of the current year
79 When used on a mobile device, {pve} will show a lightweight touch-based
