Key benefits of XenServer for server virtualization

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 virtual machine 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 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 server virtualization platform — to leverage server consolidation and dramatically affect the economics of delivering IT.  

Free hypervisors with limited functionality have been around for a long time. We see this move as substantially different because it offers a competitive, enterprise-ready virtual infrastructure platform with full centralized management, live motion and support for unlimited virtual machines and servers—with no strings attached. Anyone who dismissed XenServer in the past as a legitimate player in the enterprise virtualization space clearly owes it to themselves to take a look at this offering.” - Mark Bowker, analyst, Enterprise Strategy Group.
