XenServer Virtual HostCitrix XenServer is a leading server virtualization and hypervisor management platform that lowers the total cost of ownership for desktop, cloud and server virtualization infrastructures. Consolidation and containment of workloads on XenServer enables organizations of any vertical or size to transform their business IT compute infrastructures, tackling the IT datacenter challenges of today’s modern businesses.

Key features:

Resilient architecture
XenServer is designed with an agile, fully replicated architecture that implements a master/slave model, where any slave can become a master with no loss of functionality or configuration. This architecture enables cloud builders to cluster hosts without incurring any additional configuration or management complexity.

Network isolation and protection
XenServer scales to 800 VLANs per pool, enabling cloud builders to provide isolation between virtual machines (VMs) and users in a multi-tenant cloud environment. Linux iptables firewall partitioning enables host segmentation, while security and network spoofing and traffic sniffing tools prevent IP address spoofing, denial of service attacks and session hijacking.

Strong open source heritage
Access to the source of technology is a key aspect of understanding and managing the risk associated with selecting cloud solutions. Xen has been under development for 10 years as an open source project, and is now part of the Linux Foundation as the Xen Project under a GPLv2 license.

High-performance virtual infrastructure
XenServer provides a complete virtual infrastructure including a 64-bit hypervisor with live migration, centralized management for virtual machines and hosts and a full complement of tools to get virtual environments up and running quickly.

XenServer provides a highly reliable, available and secure open source virtualization platform that offers near-native performance and best-in-class VM density. The solution takes just 10 minutes to install using an intuitive, wizard-driven utility for easy server, storage and network setup.

XenCenter management
XenCenter provides all VM monitoring, management and general administration functions through a single, intuitive interface. XenCenter is a highly available management architecture with no single point of failure, as it shares all management and configuration data across all servers in a resource pool without the need for a separate database.

Citrix XenMotion eliminates the need for planned downtime to perform hardware and software upgrades. It allows live, running VMs to be moved from one host to another within a resource pool with no application or service outage. Move live, running VMs and their associated virtual disk image within and across resource pools, leveraging local and shared storage.

XenServer Conversion Manager
XenServer Conversion Manager provides a simple batch conversion tool to automate the process of converting VMware VMs into XenServer VMs.

Datacenter automation
Use XenServer to streamline critical tasks, maintain a manageable disaster recovery plan, increase server performance and reduce power consumption.

High availability
Automatic restart capability allows IT teams to restart VMs if a failure occurs at the VM, hypervisor or server level, and to bond network interfaces for network redundancy. Auto restart helps protect virtualized applications and bring higher levels of availability to the business.

Site recovery
Create a site-to-site disaster recovery plan for virtual environments. Site recovery is easy to set up and fast to recover, and allows frequent testing to ensure disaster recovery plans remain valid.

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.

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

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

Advanced integration and management
XenServer optimizes computing resources with a deep integration between physical and virtual resources that enables rapid provisioning, storage integration, tiered access to VMs and granular management of virtual environments.

Optimize XenServer for Citrix XenDesktop deployments by utilizing local storage for boot images and non-persistent data.

Heterogeneous pools
Enable resource pools that contain host servers with different processor types while fully supporting XenMotion, high availability and shared storage functionality.

Role-based administration
Improve VM security by maintaining a tiered access structure with varying levels of permissions.

Performance reporting and alerting
Receive immediate notification with historical reporting of VM performance for rapid identification and diagnosis of fault or failure in the virtual infrastructure.
