Key benefits

XenServer has fast become a leading server virtualization technology with over 5,000 customers and enterprise-class features that rival leading virtualization platforms. XenServer, as recently reviewed by Allan Stevens of ZDnet, “is very much a production-class virtualization solution with features that match, and in some cases exceed, what’s available on rival platforms.”

• Best virtualization value – Starting with the virtualization power of the industry-leading Xen® hypervisor at no cost, users can extend their server consolidation savings into capital equipment, space, power and cooling costs.
• Enterprise-class features – Centralized multi-server management and live migration using XenMotion enables users to manage the virtualized environment easily and intelligently while optimizing resource with zero-downtime to users.
• Easy setup and administration – Being easy to use is just one reason XenServer was named the Most Innovative Product of the Year for virtualization in 2008 by VARBusiness. XenServer can be installed and running in about 10 minutes (10 to Xen) and also has a unique management architecture that eliminates single points of failure. Easily manage hundreds of virtual machines with the included XenCenter management console that installs with only 4 megabytes of storage.

Available at no cost, Citrix XenServer gives organizations a way to widely adopt an enterprise-class, cloud-proven virtualization platform to dramatically affect the economics of delivering IT.
