   1 Host System Administration
   2 ==========================

   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.

  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].
