New Citrix XenServer Now Available from Hundreds of Websites Worldwide, Bringing Free Enterprise-Class Virtualization to Everyone

Citrix Systems, Inc. (Nasdaq:CTXS) today announced that the new free version of Citrix® XenServer™ is now available for download from more than 250 websites in 50 countries worldwide. Today’s announcement delivers on the strategy unveiled on February 23, when Citrix announced that the full enterprise-class XenServer virtual infrastructure platform, now in production in more than 5,000 enterprise datacenters worldwide, would be offered for unlimited production deployment at no charge. While basic hypervisors have been free for years, most have had limited practical use in real world environments. By offering the enterprise-class, cloud-proven XenServer platform at no cost, Citrix is helping customers address today’s challenging global economic climate while also setting an entirely new standard for free virtualization with powerful features such as centralized multi-node management, and full live motion. The imminent availability of free enterprise-class virtualization has been met with an overwhelmingly positive response from the IT community in the four weeks since the new version was announced, with a record number of customers downloading the 30-day trial preview from the Citrix website. With today’s news, customers can now download the full version of XenServer from an extensive and growing list of download sites around the world.

Users of the free XenServer product who wish to add more advanced virtualization management capabilities in the future will also be able to purchase Citrix Essentials™ for XenServer, a new product line also announced on February 23 that includes a rich set of capabilities specifically optimized for the XenServer environment. These optional features – including lab automation, dynamic provisioning, workflow orchestration, high availability and seamless integration with leading storage systems – will be directly visible to all XenServer users from their XenCenter centralized administration console in grayed-out mode, making it easy for them to understand the additional capabilities available for additional purchase should their needs change over time. As Citrix adds new enhancements to the Citrix Essentials product line, all active XenServer users will have the option to be automatically notified of these new capabilities through their XenCenter management console.

Customers using Microsoft Windows Server 2008 Hyper-V for their virtualization platform will also be able to add similar advanced virtualization management capabilities to their environments by purchasing Citrix Essentials™ for Hyper-V™. With the Citrix Essentials product line, Citrix is committed to adding significant value to both XenServer and Hyper-V, the two fastest growing virtualization platforms in the market, helping customers in all market segments achieve more manageable, scalable and agile datacenters in a way that leverages their existing investments in the most efficient way possible. More information about Citrix XenServer and Citrix Essentials can be found at http://www.citrix.com/xenserver.

Availability

The Citrix Essentials product line will be available through channel partners on April 7, 2009. Customers can download the free unlimited use version of Citrix XenServer today from multiple Citrix websites worldwide as well as any of the following third-party download locations:
