1 | Host System Administration | |
2 | ========================== | |
3 | include::attributes.txt[] | |
4 | ||
5 | {pve} is based on the famous https://www.debian.org/[Debian] Linux | |
6 | distribution. That means that you have access to the whole world of | |
7 | Debian packages, and the base system is well documented. The | |
8 | https://debian-handbook.info/download/stable/debian-handbook.pdf[Debian | |
9 | Administrator\'s Handbook] is available online, and provides a | |
10 | comprehensive introduction to the Debian operating system (see | |
11 | xref:Hertzog13[]). | |
12 | ||
13 | A standard {pve} installation uses the default repositories from | |
14 | Debian, so you get bug fixes and security updates through that | |
15 | channel. In addition, we provide our own package repository to roll | |
16 | out all {pve} related packages. This includes updates to some | |
17 | Debian packages when necessary. | |
18 | ||
19 | We also deliver a specially optimized Linux kernel, where we enable all | |
20 | required virtualization and container features. That kernel includes | |
21 | drivers for http://zfsonlinux.org/[ZFS], and several hardware drivers. | |
22 | For example, we ship Intel network card drivers to support their | |
23 | newest hardware. | |
24 | ||
25 | The following sections will concentrate on virtualization related | |
26 | topics. They either explains things which are different on {pve}, or | |
27 | tasks which are commonly used on {pve}. For other topics, please refer | |
28 | to the standard Debian documentation. | |
29 | ||
30 | System requirements | |
31 | ------------------- | |
32 | ||
33 | For production servers, high quality server equipment is needed. Keep | |
34 | in mind, if you run 10 Virtual Servers on one machine and you then | |
35 | experience a hardware failure, 10 services are lost. {pve} | |
36 | supports clustering, this means that multiple {pve} installations | |
37 | can be centrally managed thanks to the included cluster functionality. | |
38 | ||
39 | {pve} can use local storage (DAS), SAN, NAS and also distributed | |
40 | storage (Ceph RBD). For details see xref:chapter-storage[chapter storage]. | |
41 | ||
42 | Minimum requirements, for evaluation | |
43 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
44 | ||
45 | * CPU: 64bit (Intel EMT64 or AMD64) | |
46 | ||
47 | * RAM: 1 GB RAM | |
48 | ||
49 | * Hard drive | |
50 | ||
51 | * One NIC | |
52 | ||
53 | Recommended system requirements | |
54 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
55 | ||
56 | * CPU: 64bit (Intel EMT64 or AMD64), Multi core CPU recommended | |
57 | ||
58 | * RAM: 8 GB is good, more is better | |
59 | ||
60 | * Hardware RAID with batteries protected write cache (BBU) or flash | |
61 | based protection | |
62 | ||
63 | * Fast hard drives, best results with 15k rpm SAS, Raid10 | |
64 | ||
65 | * At least two NICĀ“s, depending on the used storage technology you need more | |
