Citrix XenServer - Technical Details

XenServer Highlights

Citrix XenServer is open, powerful server virtualization that radically reduces datacenter costs by transforming static and complex datacenter environments into more dynamic, easy to manage server workload delivery centers.

•	XenServer is based on Xen - the compact, open source hypervisor that delivers near bare-metal performance. It is supported by organizations such as Intel, AMD, HP and more than forty others.
•	XenServer is easy to deploy, and its wizard-based controls and advanced capabilities mean more servers per administrator and zero-downtime for upgrades.
•	Hyper-V compatibility allows you to run any mixture of XenServer and Hyper-V and move workloads between them.
•	Unique snap-in storage architecture leverages existing array-based storage services.
•	XenMotion allows the movement of any type of workload to any server with zero downtime and maximum resource utilization.
