Before designing its seventh generation SBC, RadiSys carefully examined Intel processor options and compared compute performance, overall cost, upgrade path and thermal requirements. The findings played a critical role in defining a price/performance optimized blade that also satisfies other TEM requirements, such as easily dropping into an existing chassis and supporting multiple storage options and virtualization. This white paper provides the results of the RadiSys analysis and presents the four key reasons why TEMs should strongly consider adopting Intel Xeon 5500 platform-based ATCA blades.
