XenServer
Citrix XenServer: Virtualization with efficiency and performance.
With XenServer, Citrix completes its range of products by managing the delivery of applications in a complete operating system server to the desktop.
Citrix XenServer virtual machines provides high-performance Windows and Linux, and a storage and management Networking with a management console user friendly.
What is Xen?
Xen is a unique open source technology, invented by a team at the University of Cambridge and developed cooperatively by the best engineers around the world.
With Virtualization Xen, a lightweight software (Xen hypervisor) is installed directly on the server and thus remains between the server hardware and operating system. This provides a level of abstraction that allows each physical server to run one or more Virtual Servers, Effectively decoupling the operating system and its applications from the underlying physical server. Hypervisor Xen is extremely light - less than 50,000 lines of code - which translates into low overhead and high performance of virtual servers.
Introducing Citrix XenServer
Inventors and developers of Xen, with the rest of the XenServer team, have taken this powerful virtualization engine and produced a fully managed virtualization platform designed for efficient management of virtual machines, Windows and Linux Citrix XenServer v4 virtualization platform is a 64-bit applications with the scalability required by business-critical. XenServer provides the highest CPU and memory resources for both Host that for Guest, coupled with a high control of CPU, network and disks, ensuring a high quality of service.
