x86 Blade Server Platforms: Cutting Through the Hype

Published: 08 September 2009

ID: G00203822

Analyst(s): Nik Simpson


Vendors continue to promote blades as the answer to data center consolidation, server virtualization, world peace, and sundry other problems. But customers are reluctant to become converts to the "Church of Blades," with blade servers capturing only 18.5%1 of the x86 server market revenues in 2008. Customer concerns include the proprietary hardware, throughput limitations, cooling, and achievable density in a typical data center. In this updated Burton Group report, Analyst Nik Simpson reviews new technologies and the impact of recent announcements (e.g., Cisco's blades and Intel's Xeon 5500) before asking the question, "Do blades make sense for enterprise x86 server deployments?"
