-Administrator\'s Handbook] is available online, and provide a
-comprehensive introduction to the Debian operating system (see
-xref:Hertzog13[]).
-
-A standard {pve} installation uses the default repositories from
-Debian, so you get bug fixes and security updates through that
-channel. In addition, we provide our own package repository to roll
-out all {pve} related packages. This includes updates to some
-Debian packages when necessary.
-
-We also deliver a specially optimized Linux kernel, where we enable all
-required virtualization and container features. That kernel includes
-drivers for http://zfsonlinux.org/[ZFS], and several hardware drivers.
-For example, we ship Intel network card drivers to support their
-newest hardware.
-
-The following sections will concentrate on virtualization related
-topics. They either explains things which are different on {pve}, or
-tasks which are commonly used on {pve}. For other topics, please refer
-to the standard Debian documentation.
-
-System requirements
--------------------
-
-For production servers, high quality server equipment is needed. Keep
-in mind, if you run 10 Virtual Servers on one machine and you then
-experience a hardware failure, 10 services are lost. {pve}
-supports clustering, this means that multiple {pve} installations
-can be centrally managed thanks to the included cluster functionality.
-
-{pve} can use local storage (DAS), SAN, NAS and also distributed
-storage (Ceph RBD). For details see xref:chapter-storage[chapter storage].
-
-Minimum requirements, for evaluation
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-* CPU: 64bit (Intel EMT64 or AMD64)
-
-* RAM: 1 GB RAM
-
-* Hard drive
-
-* One NIC
-
-Recommended system requirements
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-* CPU: 64bit (Intel EMT64 or AMD64), Multi core CPU recommended
-
-* RAM: 8 GB is good, more is better
-
-* Hardware RAID with batteries protected write cache (BBU) or flash
- based protection
-
-* Fast hard drives, best results with 15k rpm SAS, Raid10
-
-* At least two NICĀ“s, depending on the used storage technology you need more
-
-
-Getting Help
-------------
-
-There are basically two different support channels. {pve} itself if
-fully open source, so we always encourage our users to discuss and
-share their knowledge using the http://forum.proxmox.com/[Community
-Support Forum]. The forum is fully moderated by the Proxmox support
-team. Up to now, the forum has about 25.000 members, and more than
-120.000 messages. Needless to say that such a large forum is a great
-place to get information.
-
-The second channel is the commercial support provided by
-{proxmoxGmbh}. {pve} server subscriptions can be ordered online, see
-http://shop.maurer-it.com[{pve} Shop]. For all details see
-http://www.proxmox.com/proxmox-ve/pricing[{pve} Subscription Service
-Plans].
-
-Please contact the mailto:office@proxmox.com[Proxmox sales team] for
-commercial support requests or volume discounts.
-
-Package Repositories
---------------------
-
-All Debian based systems use
-http://en.wikipedia.org/wiki/Advanced_Packaging_Tool[APT] as package
-management tool. The list of repositories is defined in
-'/etc/apt/sources.list' and '.list' files found inside
-'/etc/apt/sources.d/'. Updates can be installed directly using
-'apt-get', or via the GUI.
-
-Apt 'sources.list' files lists one package repository per line, with
-the most preferred source listed first. Empty lines are ignored, and a
-'#' character anywhere on a line marks the remainder of that line as a
-comment. The information available from the configured sources is
-acquired by 'apt-get update'.
-
-.File '/etc/apt/sources.list'
-----
-deb http://ftp.debian.org/debian jessie main contrib
-
-# security updates
-deb http://security.debian.org jessie/updates main contrib
-----
-
-In addition, {pve} provides three different package repositories.
