XenServer :Complete, cost-effective datacenter and server virtualization

Citrix XenServer is a complete, managed server virtualization platform built on the powerful Xen hypervisor. Xen technology is widely acknowledged as the fastest and most secure virtualization software in the industry. XenServer is designed for efficient management of Windows® and Linux® virtual servers and delivers cost-effective server consolidation and business continuity.


Server virtualization is a proven technology that enables multiple virtual machines to run on a single physical server. Each virtual machine is completely isolated from other virtual machines and is decoupled from the underlying host by a thin layer of software known as a hypervisor. This allows each virtual machine to run different operating systems and applications. Because the machines have been decoupled from the underlying host, the guest can also be moved from one physical server host to another while running; this is known as live migration. These attributes are transforming how organizations approach virtual computing.


XenServer is the enterprise-ready, cloud-proven virtualization platform that contains all the capabilities required to create and manage a virtual infrastructure. It is trusted by demanding organizations to run the most mission critical applications and used by the largest clouds.
  • Cuts costs: By reducing the number of physical servers required in the datacenter, organizations are able to save on their power and cooling costs.
  • Increases IT agility and efficiency: Customers can easily adapt to changing datacenter and computing needs by dynamically flexing capacity, optimizing VM placement, and automating repetitive management tasks.
  • Improves performance and user productivity: By enabling ‘zero downtime’ maintenance, automatically recovering from hardware failure, and providing failover capabilities in disaster situations, end users are ensured access to mission critical application in all scenarios.
The free edition of XenServer starts with a 64-bit hypervisor and centralized management, live migration, and conversion tools to create a virtual platform that maximizes guest density and performance. The premium editions of XenServer extend the platform to enable organizations of any size to integrate and automate management processes, delivering a virtual datacenter solution.

XenServer Features

From managing infrastructure to optimizing on-going IT operations, and from automating key processes through to delivering IT services, XenServer has the capabilities that fit any organizations IT requirements and enable businesses to transform their datacenters into IT delivery centers.


With Citrix XenServer, organizations can automate key IT processes to improve service delivery and business continuity for virtual environments resulting in both time and money savings while providing more responsive IT services.

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.

Host Power Management

Takes 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.

Dynamic Workload Balancing

Improves system utilization and increases application performance by automatically balancing two virtual machines within a resource pool. Workload balancing intelligently places VMs on the most suitable host in the resource pool by matching application requirements to available hardware resources.

Automated VM Protection and Recovery

Utilizing an easy set-up wizard, administrators can create snapshot and archival policies. Regularly scheduled snapshots help to protect against data loss in case of a VM failure. The policies established are based on snapshot type, frequency, amount of historical data that is retained, and an archive location. Recovering a VM is completed by simply choosing the last good known archive.

High Availability

Automatically restarts virtual machines if a failure occurs at the VM, hypervisor, or server level. The auto restart capability allows users to protect all virtualized applications and bring higher levels of availability to the business.

Memory Optimization

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


With enhanced editions of Citrix XenServer, customers can also leverage advanced functions that enable a deep integration between physical and virtual resources and allow for more granular management virtual environments.
Citrix XenDesktops are provided by Acenseo


Citrix StorageLink provides integration with leading network storage platforms which enables storage managers to leverage existing data management tools to maintain consistent management processes for both physical and virtual environments. Key data management processes can be instantiated from a single StorageLink interface.

Distributed Virtual Switching

Create a multi-tenant, highly secure and extremely flexible network fabric that allows VMs to move freely within the network while maintaining security and control. Distributed virtual switching bridges subnets to provide stateful migration of VMs between networks and between on-premise and cloud networks without manual intervention.

Web Console with Delegated Admin

Web Self Service provides IT administrators with a simple web-based console to delegate individual VM rights to application owners as well as a way for application owners to manage day to day operations of their VM’s.

Heterogeneous Pools

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

Provisioning Services

Reduce storage requirements by creating a set of golden images which can be streamed to both physical and virtual servers for fast, consistent, and reliable application deployments.

Role-based Administration

Role-based administration improves security and enables delegated access, control, and usage of XenServer pools by maintaining a tiered access structure with varying levels of permissions.


XenServer is optimized to reduce the overall costs and improve performance of a XenDesktop installation. By using local storage as a repository for boot images and non-persistent or temporary data, XenServer can reduce virtual desktop boot times, decrease network volume and traffic, and save on total storage costs for a XenDesktop installation.

Performance Reporting and Alerting

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


With Citrix XenServer, organizations can automate key IT processes to improve service delivery and business continuity for virtual environments resulting in both time and money savings while providing more responsive IT services.
Acenseo network security consultants are the leading resellers of the Citrix XenDesktop


Based on the open-source design of Xen, XenServer is a highly reliable, available, and secure virtualization platform that utilizes a 64-bit architecture to provide near native application performance and unmatched virtual machine density. XenServer allows for easy server, storage, and network setup via an intuitive wizard-driven utility that delivers Ten Minutes to Xen. Disk snapshot and revert creates periodic snapshots of virtual machines and data for easy recovery to a known working state in case of failure. Disk snapshots can also be cloned to speed system provisioning.

XenCenter Multi-Server Management

Citrix XenCenter provides all the VM monitoring, management, and general administration functions in a single interface including configuration, patch management, and virtual machine libraries. IT staff can easily manage hundreds ofvirtual machines from a centralized, highly available management console that installs on any Windows® desktop. The Resilient Distributed Management Architecture distributes server management data across the servers in a resource pool to ensure that there is no single point of management failure. If a management server should fail, any other server in the pool can take over the management role.

Conversion Tools

Convert physical and virtual servers (P2V and/or V2V) for faster setup and migration making the transformation to XenServer nearly instantaneous. The conversion tools included in XenServer can convert any physical server or desktop workload and existing virtual machines to a XenServer virtual machine.


Citrix 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.
