Citrix XenServer™, a member of the Citrix Delivery Center product family, is the simplest and most effective way to virtualize servers and deliver dynamic data centers that are responsive to the ever-changing demands of business. Using Citrix XenServer, companies can deploy high-performance virtual machines rapidly and easily, and manage them and their related storage and networking resources from a single easy-to-use management console.
The powerful provisioning capabilities now available in Citrix XenServer makes it the only platform than can integrate the deployment and management of virtual and physical servers into a unified dynamic virtualized infrastructure — a flexible aggregated pool of computing and storage resources.
Unlock the Power of
Server Virtualization
A thin software layer
(known as the Xen
hypervisor) runs
directly on the hardware
and provides an
abstraction layer that
allows each physical
server to run one or
more virtual servers,
breaking the
“hard-coding” that
normally locks the
operating system its
applications to the
underlying physical
server. Each virtual
server appears to users
and to management
software as if it were a
separate physical
computer, but in fact,
many virtual servers may
share one physical
server — the density of
consolidation is limited
only by available
resources.
XenServer’s virtualization technology is widely acknowledged as the fastest and most secure in the industry, and is enhanced by taking full advantage of the latest Intel VT and AMD-V hardware virtualization assist capabilities.
Citrix XenServer combines the performance, security, and openness of the Xen technology with XenCenter comprehensive management — yielding a platform perfect for rapid adoption of virtualization for server consolidation, software development and test, and business continuity.
Increased Agility at
Lower Cost
With Citrix XenServer
virtualization,
businesses can increase
server and storage
utilization, reducing
costs of equipment,
power, cooling, and real
estate.
Virtualization-powered
consolidation enables
businesses to
decommission older
systems that are
expensive to support and
prone to failure,
replacing several of
them with a single
newer, more supportable,
less power-hungry
system.
By combining servers and storage into resource pools that can be apportioned to the applications with the highest business need, IT operations can be aligned to changing demand and business priorities. With XenMotion, running virtual machines can be migrated to new servers with no service interruption, allowing essential workloads to get needed resources and enable zero-downtime maintenance.
Easy to Deploy and
Integrate
Citrix XenServer is
installed directly on
bare metal servers,
requiring no dedicated
host operating system.
Open command-line (CLI)
and programming (API)
interfaces make it easy
for vendors and
enterprises to integrate
virtualization with
existing processes and
management tools. The
powerful provisioning
capabilities make it
possible to deliver new
servers hosting new
application services in
minutes, with efficient
use of storage
resources.
Secure and Reliable
The centralization
provided by Citrix
XenServer - especially
when combined with the
optimized application
delivery pipeline of the
Citrix Delivery Center -
leaves valuable data in
the well-protected data
center, rather than on
the road or on open
networks where it is
more vulnerable to loss.
Internal networks and
virtual firewalls can be
used to make secure
processes or back-end
application tiers
visible only to the
systems that need
access, rather than
being open to the world.
Citrix XenServer’s management information is stored redundantly across managed servers, making the Resource Pool resilient in the face of failure of any one system. Workloads on a failed system can be restarted quickly on any other available server, dramatically reducing the downtime that can interfere with business. For planned maintenance, running virtual machines can be migrated to other physical servers without interruption of service — eliminating scheduled downtime.
