5{pve} is based on the famous https://www.debian.org/[Debian] Linux
6distribution. That means that you have access to the whole world of
7Debian packages, and the base system is well documented. The
8https://debian-handbook.info/download/stable/debian-handbook.pdf[Debian
65647b07 9Administrator\'s Handbook] is available online, and provides a
419ef454
DM
10comprehensive introduction to the Debian operating system (see
11xref:Hertzog13[]).
12
13A standard {pve} installation uses the default repositories from
14Debian, so you get bug fixes and security updates through that
15channel. In addition, we provide our own package repository to roll
16out all {pve} related packages. This includes updates to some
17Debian packages when necessary.
18
19We also deliver a specially optimized Linux kernel, where we enable all
20required virtualization and container features. That kernel includes
21drivers for http://zfsonlinux.org/[ZFS], and several hardware drivers.
22For example, we ship Intel network card drivers to support their
23newest hardware.
24
25The following sections will concentrate on virtualization related
26topics. They either explains things which are different on {pve}, or
27tasks which are commonly used on {pve}. For other topics, please refer
28to the standard Debian documentation.

30System requirements
31-------------------
32
33For production servers, high quality server equipment is needed. Keep
34in mind, if you run 10 Virtual Servers on one machine and you then
35experience a hardware failure, 10 services are lost. {pve}
36supports clustering, this means that multiple {pve} installations
37can be centrally managed thanks to the included cluster functionality.
38
39{pve} can use local storage (DAS), SAN, NAS and also distributed
40storage (Ceph RBD). For details see xref:chapter-storage[chapter storage].
