Citrix Certifies XenServer for Intel Environments

Participation in Intel Enabled Server Acceleration Alliance (ESAA) Enables Citrix Partners to Deliver World-Class Virtualization Solutions based on Intel and Citrix Products

BOSTON - Citrix Systems, Inc. (NASDAQ:CTXS), the global leader in application delivery infrastructure, today announced that it has certified its XenServer™ solutions for use in Intel-based environments as a member of the Intel® Enabled Server Acceleration Alliance (Intel® ESAA). A member of the Intel ESAA program since 2006, Citrix now enables the creation of pre-validated “recipes” that joint channel partners can use to deliver world-class virtualization solution stacks based on Intel® Server Products and Citrix® XenServer. As a result, resellers reduce the engineering effort needed to deliver world-class virtualization solution stacks while end-customers gain access to tightly integrated hardware and software and world-class support directly from Intel and Citrix.

“The relationship between Intel and Citrix has grown into a powerful collaboration,” said Ned Thanhouser, director, Intel ESAA program. “Intel ESAA solution recipes based on Citrix XenServer let resellers deliver advanced virtualization capabilities for businesses of all shapes and sizes and provide a significant opportunity for our channel.”

Intel ESAA is a collaborative program that streamlines technical certification and validation of reliable, high-quality server solutions to end-user customers. The certification allows Intel OEM and channel partners to quickly deliver pre-configured, Intel-based solutions to their customers. Solution builders are assured that Intel ESAA solutions consist of equipment and software from trusted technology providers, and end-user customers have confidence knowing they are purchasing a pre-tested and validated solution.

“With the increasing complexity of virtualization solution stacks, resellers and customers need pre-validation they can depend on,” said Frank Artale, vice president, business development, Citrix Systems. “Working together, Citrix and Intel can help build that level of confidence.”
