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 | |
426fbd5f | 9 | a cluster with highly available (HA) virtual machines and containers. |

426fbd5f AL |
11 | {pve} can use local storage (DAS), SAN, NAS, and distributed storage like Ceph |
12 | RBD. For details see xref:chapter_storage[chapter storage]. | |

e40349c6 | 15 | Minimum Requirements, for Evaluation |
bc1c71d4 DM |
16 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |

426fbd5f AL |
18 | These minimum requirements are for evaluation purposes only and should not be |
19 | used in production. | |
20 | ||
bc1c71d4 DM |
21 | * CPU: 64bit (Intel EMT64 or AMD64) |
22 | ||
42dfa5e9 | 23 | * Intel VT/AMD-V capable CPU/motherboard for KVM full virtualization support |
bc1c71d4 | 24 | |
3f7218b5 | 25 | * RAM: 1 GB RAM, plus additional RAM needed for guests |

26 | |
27 | * Hard drive | |
28 | ||
3f7218b5 | 29 | * One network card (NIC) |

e40349c6 | 33 | Recommended System Requirements |
bc1c71d4 DM |
34 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
35 | ||
58610ec9 | 36 | * Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag. |
bc1c71d4 | 37 | |
3f7218b5 DW |
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 | |
426fbd5f | 40 | memory for every TB of used storage. |
58610ec9 | 41 | |
426fbd5f | 42 | * Fast and redundant storage, best results are achieved with SSDs. |
bc1c71d4 | 43 | |
426fbd5f AL |
44 | * OS storage: Use a hardware RAID with battery protected write cache (``BBU'') |
45 | or non-RAID with ZFS (optional SSD for ZIL). | |
bc1c71d4 | 46 | |
426fbd5f | 47 | * VM storage: |
3f7218b5 | 48 | ** For local storage, use either a hardware RAID with battery backed write cache |
426fbd5f AL |
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. | |
bc1c71d4 | 52 | |
3f7218b5 | 53 | * Redundant (Multi-)Gbit NICs, with additional NICs depending on the preferred |
426fbd5f | 54 | storage technology and cluster setup. |
bc1c71d4 | 55 | |
426fbd5f | 56 | * For PCI(e) passthrough the CPU needs to support the VT-d/AMD-d flag. |

426fbd5f AL |
62 | To get an overview of the CPU and hard disk performance on an installed {pve} |
63 | system, run the included `pveperf` tool. | |

6a575420 | 65 | NOTE: This is just a very quick and general benchmark. More detailed tests are |
d3e2455a | 66 | recommended, especially regarding the I/O performance of your system. |

71 | To access the web-based user interface, we recommend using one of the following |
72 | browsers: | |
426fbd5f | 73 | |
3f7218b5 DW |
74 | * Firefox, a release from the current year, or the latest Extended Support Release |
75 | * Chrome, a release from the current year | |
426fbd5f | 76 | * Microsoft's currently supported version of Edge |
3f7218b5 | 77 | * Safari, a release from the current year |
69255fd2 | 78 | |
3f7218b5 | 79 | When accessed from a mobile device, {pve} will show a lightweight, touch-based |
426fbd5f | 80 | interface. |
