Xen is a unique open source technology invented by a team led by Ian Pratt at the University of Cambridge and developed cooperatively by the world’s best engineers at over 20 of the most innovative datacenter solution vendors. With Xen server virtualization solutions, a thin software layer (known as the Xen hypervisor) is installed directly on the hardware, or bare metal, and is thereby inserted between the server’s hardware and the operating system. This provides an abstraction layer 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. Xen’s paravirtualization technology is widely acknowledged as the fastest and most secure virtualization software in the industry and is enhanced by taking full advantage of the latest Intel® VT and AMD-V™ hardware virtualization assist capabilities. The Xen hypervisor is exceptionally lean - less than 50,000 lines of code -– which translates to extremely low overhead and near-native performance for guests.
Citrix XenServer 5
Virtualization for every server in the enterprise.
Any Server. Anywhere. Anytime.
Citrix XenServer™ is server virtualization that makes datacenters more agile and efficient through faster application delivery, higher levels of availability and improved utilization of IT resources.
XenServer delivers the advanced features required by mission critical workloads without sacrificing the ease-of-use necessary for wide-scale deployments. The unique provisioning technology of XenServer can rapidly deliver workloads across virtual or physical servers making it the ideal virtualization platform for every server in the enterprise.
Uniquely open
XenServer is based on the open source Xen® hypervisor, an exceptionally lean technology that delivers low overhead and near-native performance. Leveraging both Intel® VT platforms and AMD® Virtualization (AMD-V™) platforms for hardware assisted virtualization, XenServer delivers faster, more efficient virtualization computing. Unlike other virtualization products that are built on closed proprietary systems, XenServer’s open APIs allow customers to access and control advanced functions from their existing server and storage hardware.
Radically simple
Citrix establishes a new standard in ease-of-use by including new configuration wizards, intuitive interfaces and easy point-and-click conversion of physical servers into virtual machines. Experience 10 to Xen as it only takes 10 minutes to install and configure XenServer. XenServer gives administrators the visibility to easily keep track of virtual machines as they proliferate across large datacenters. Web 2.0 style tagging and searching capabilities allow IT professionals to assign metadata and virtual tags to workloads, either pre-defined or customized to each organization’s needs. XenServer’s performance monitoring, reporting and alerting dashboards make it easy to see both real-time and historical views of virtual machines and physical host performance over long periods of time with virtually no storage or performance overhead.
Seriously powerful
Ready to get serious about server virtualization? Building on long list of proven enterprise-class features such as live migration, resource pooling and workload provisioning, the newest version of XenServer adds more than 100 new virtualization enhancements including advances in high availability (HA) and disaster recovery. These capabilities include the industry’s most advanced HA, auto-restart and failover technologies that can be seamlessly upgraded to full fault tolerance for the most mission-critical applications.
