Citrix Introduces Next-Generation XenServer

Full 64-bit Architecture Delivers Industry-leading GPU Virtualization and Extreme Performance and Scalability for VDI, Server Virtualization and Cloud

SANTA CLARA, Calif. – Today, Citrix announced XenServer® 6.5, the newest release of the company’s commercial virtualization platform based on the open-source Xen Project hypervisor. XenServer now offers a full 64-bit kernel architecture that allows customers to take advantage of the latest hardware and OS platforms, and supports enterprise-grade networking, storage and workload management. XenServer supports Intel® Trusted Execution Technology (Intel® TXT), which provides tamper detection of the hypervisor, preventing applications running on a potentially compromised machine. New to this release, asset tagging enables workload geo-tagging, providing users with a way to restrict workloads to run in a particular location for security reasons.  XenServer further extends the company’s industry-leading GPU virtualization capabilities supporting NVIDIA GRID™ vGPU™ technology and delivers a 50 percent increase in server density for delivering high-end 3D graphics applications in virtual desktops. With its next-generation kernel architecture supporting both enterprise-grade and carrier-grade features, XenServer is the most comprehensive, cost-effective and open virtualization platform choice for enterprises and service providers.

To meet with the demands of the evolving mobile enterprise, customers need cloud infrastructure technology that maximizes the flexibility and efficiency of both end-user workspaces and datacenter operations, all in a secure manner. XenServer is a crucial piece of this cloud infrastructure, running mission-critical workloads for some of the world’s largest communication service providers, cloud service providers and enterprises. As an example, 50 percent of XenDesktop® deployments are run on XenServer. Benefits to enterprise and service provider customers include increased operational agility and flexibility by delivering new and existing workloads more quickly, reliably and in greater quantities; enhanced IT efficiencies through higher infrastructure utilization and consolidation ratios; and lower TCO of datacenter operations by maximizing and optimizing infrastructure and capacity utilization.

New Architecture Delivers Improved Performance

The new 64-bit kernel architecture has resulted in dramatic improvements in networking and storage performance, providing customers with a powerful virtualization platform for running new and existing workloads in their workspace and datacenter environments. As part of this release, enterprise-class features for workload balancing (WLB) and distributed virtual switch controller (DVSC) have also been re-introduced. All these improvements now extend XenServer as the lead choice of some of the largest and most sophisticated clouds in the world.

Industry-leading GPU Virtualization with NVIDIA GRID vGPU Technology

XenServer is the industry’s only open enterprise-grade and carrier-grade virtualization platform delivering highly-scalable GPU virtualization support for NVIDIA GRID vGPU technology and native cloud integration for CloudPlatform™, and other non-proprietary cloud management platforms. With a 50 percent increase in server density, customers using XenDesktop and XenApp® to deliver high-end 3D graphics apps can now achieve a greater density of desktops using XenServer, resulting in dramatically reduced costs and improved end-user experience.

It’s no exaggeration to say that over the past four years, our cloud has grown tremendously as a result of the performance and reliability of Citrix XenServer. The stability and performance of the Citrix XenServer hypervisor has undoubtedly contributed to the growth of our cloud in terms of quality, profitability and competitiveness as an IaaS provider. We look forward to continuing to grow as a global IaaS cloud provider by delivering competitive, reliable and high-performance services based on Citrix XenServer. KT currently has 3,000 hosts running in its KT public cloud and private cloud IaaS Service – most are operated and managed by Citrix CloudPlatform, which is one of the best Citrix products.

XenServer has helped NAU virtualize scores of servers that previously ran standalone - with more flexibility and higher availability than ever before. Being able to bring up a brand new XenDesktop/XenApp environment consisting of several hundred clients hosted under XenServer in just a few months attests to the confidence we had and have in this product and platform. Citrix listens to what its customers say, and strives to be cognizant of the needs and desires of its user community. The flexibility in XenServer to migrate VMs and storage around has virtually obviated the need for system administrators to come in at 3AM to perform maintenance tasks with XenServer allowing us to maintain 99+ percent uptime while keeping normal working hours.
