Burton Certifies Citrix XenServer 5.5 as 100 Percent Enterprise Production-Ready

Burton Group analysts will also be presenting the evaluation criteria for its enterprise production-ready certification. Citrix® XenServer 5.5 with Citrix Essentials 5.5 Platinum Edition recently became one of only two hypervisor platforms in the industry that the analyst firm has recognized as meeting 100 percent of the required features for enterprise production.

"To be certified as enterprise production-ready under Burton Group’s server virtualization hypervisor evaluation criteria, a server virtualization platform must meet all 27 of our stated feature requirements,” said Chris Wolf, senior analyst, Burton Group. "Enterprise production-ready hypervisors pass a rigorous examination of their compute, storage, networking, security, and management capabilities, and achieve a passing score of 100 percent with regards to required features.”

Citrix XenServer 5.5 became generally available on June 16, just 75 days after Citrix unveiled the full enterprise-class XenServer platform for unlimited production deployment at no charge. Unlike basic hypervisors that have been free for years, XenServer sets an entirely new standard for free virtualization with powerful features such as centralized multi-node management, built-in storage and full live motion. Since unveiling free enterprise-ready XenServer, more than 140,000 customers worldwide have downloaded the product with overwhelmingly positive feedback. By providing these customers with a free, fully featured alternative to existing commercial products, Citrix has saved customers millions of dollars and provided compelling value to IT organizations as they face shrinking budgets.

The 5.5 release of Citrix Essentials for XenServer and Hyper-V, provides advanced virtualization management capabilities for customers using Citrix XenServer or Microsoft® Windows Server® 2008 Hyper-V. Citrix Essentials 5.5 enhances both of these high-growth virtualization platforms by adding expanded storage integration, automated lab and stage management and dynamic workload balancing. It also complements XenDesktop, with support for both server and desktop workloads.

XenServer 5.5 is immediately available for download at http://www.citrix.com/freexenserver, as well as hundreds of other download sites worldwide. Citrix Essentials 5.5 for XenServer and Hyper-V are also available for purchase or a 30-day trial version at http://www.citrix.com/essentials.
