Overview - XenServer
XenServer is an open source virtualization platform built on the powerful Xen Project hypervisor that offers near bare-metal performance for virtualized server and client operating systems. With XenServer, a rack of servers can become a highly available compute cluster that protects key application workloads, leveraging industry standard storage architectures and offering no-downtime maintenance by allowing virtual machines and associated storage to be moved while they are running between machines in the cluster. XenServer extends the most powerful abstraction: virtualization across servers, storage and networking to enable users to realize the full potential of a dynamic, responsive, efficient data center and cloud environments for Windows and Linux workloads.
XenServer is ideally suited for organizations seeking to maximize the benefits of server consolidation, automating software test and development and assigning resource and protection levels for performance-sensitive production workloads. IT administrators get a simple and painless solution for virtualizing any workload with unified control of server clusters, storage resources and virtual machine management.
