Core Platform

XenServer is based on the Xen Project™ hypervisor. The Xen Project hypervisor is a bare metal virtualization paltform used by XenServer to deliver near native application performance for x86 workloads in an Intel and AMD environment.

Scalable Virtual Infrastructure

Roles Based Access Control

Control access to critical infrastructure resources by delegating access through RBAC.

Live VM Migration

XenMotion™ eliminates the need for planned downtime by enabling active virtual machines to be moved to a new host with no application outages or downtime.

Live Storage Migration

Move live running virtual machines and their associated virtual disk image within and across resource pools leveraging local and shared storage. This enables users to move a VM and its virtual disk image from a development to production environment, move between tiers of storage when a VM is limited by storage capacity, and perform maintenance and upgrades with zero downtime.

Host Failure Protection

Deliver high availability by automatically restarting virtual machines if a failure occurs at the VM, hypervisor or server level. Link aggregation bonds network interfaces for network redundancy and increased throughput.

Host Power Management

Take advantage of embedded hardware features to lower datacenter electricity consumption by dynamically consolidating VMs on fewer systems and then powering off underutilized servers as demand for services fluctuates.

Memory Overcommit

Reduce costs and improve application performance and protection by sharing unused server memory between VMs on the host server.

Virtual Machine Snapshot and Revert

Create snapshots of virtual machines to capture disk and metadata settings for backups, archives and configuration changes.

Heterogeneous Resource Pools

Enables resource pools to contain servers with different processor types, and support full XenMotion, high availability, and shared storage functionality.

Site Recovery

Provides site-to-site disaster recovery planning and services for virtual environments. Site recovery is easy to set up, fast to recover, and has the ability to frequently test to ensure disaster recovery plans remain valid.
