Key benefits

XenServer has fast become a leading virtualization technology with over 5,000 customers and enterprise-class features that rival leading virtualization platforms.  XenServer, as recently reviewed by Allan Stevens of ZDnet, “is very much a production-class virtualization solution with features that match, and in some cases exceed, what’s available on rival platforms.”


Best virtualization value – Starting with the virtualization power of the industry-leading Xen® hypervisor at no cost, users can extend their savings into capital equipment, space, power and cooling costs.
Enterprise-class features – Centralized multi-server management and live migration using XenMotion enables users to manage the virtualized environment easily and intelligently while optimizing resource with zero-downtime to users.
Easy setup and administration – Being easy to use is just one reason XenServer was named the Most Innovative Product of the Year for virtualization in 2008 by VARBusiness.  XenServer can be installed and running in about 10 minutes (10 to Xen) and also has a unique management architecture that eliminates single points of failure.  Easily manage hundreds of virtual machines with the included XenCenter management console that installs with only 4 megabytes of storage.
Available at no cost, Citrix XenServer gives organizations a way to widely adopt an enterprise-class, cloud-proven virtualization platform to dramatically affect the economics of delivering IT. 

Citrix Essentials

Advanced automation and management for the virtual datacenter

Citrix Essentials™ for XenServer and Hyper-V™ provides a set of management and automation capabilities that extends the capabilities of either the free Citrix XenServer or Microsoft Hyper-V to help customers transform datacenters into proactive and automated delivery centers. 

Citrix Essentials for XenServer includes:

• Automated lab management streamlines the process of building, testing, sharing and delivering applications on-demand throughout the full application lifecycle, from development labs to production servers.
• Advanced storage integration featuring Citrix StorageLink™ technology fully leverages all the native power of third-party array-based storage systems making it easy for customers to manage advanced storage features directly from their virtualization management environments.
• Dynamic provisioning services reduces costs and optimizes datacenter infrastructure by letting customers manage a common set of master workload images centrally, then stream them on-demand to any combination of virtual machines or physical servers.
• Workflow orchestration enables users to automate key management processes across their virtual infrastructure using common task libraries and a graphical workflow canvas.
• High availability delivers a broad range of powerful high availability options from automatic restart to workload balancing of virtual machines across resource pools based on preset thresholds.
• One of the most powerful and innovative new features in the Citrix Essentials product line is the Citrix StorageLink™ technology, which dramatically reduces the cost and complexity of storage management by making it easy to leverage all the power of existing storage systems from within both XenServer and Hyper-V virtualization environments.
