Maximizing Memory Resources on Xeon 5500-based ATCA blades (GFT-757A)

This paper provides a review of the Intel® 55xx series Nehalem Xeon® processor basic memory subsystem architecture, a discussion of design and application tradeoffs that need to be managed when defining the memory subsystem, and an overview of the main memory resources provided on the GE Intelligent Platforms A10200 AdvancedTCA® Nehalem-based single board computer (SBC). It is assumed that the reader is generally familiar with cache and MMU operation, as well as the NUMA (non-uniform memory architecture) used by Intel and others to optimize physical memory resource allocation for simultaneous data accesses on multiple memory channels.
