From GE Intelligent Platforms

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.

Panel Computers
Panel PCs are specialized computers that are designed for industrial applications. The personal computer or PC is embedded in a flange or panel, allowing operators to monitor or manage industrial processes.
Industrial Chassis and Card Cages
Industrial chassis and card cages are metal frames that support and contain electronic components and power supplies. They generally have a backplane with slots to install other peripherals and accessories.
Multipurpose Computer Boards
Multipurpose computer boards can perform numerous, related functions. Examples include modem/fax cards, modem/Ethernet cards, and serial/parallel adapters.
IndustryPack® Modules
IndustryPack® modules are computer boards that interface with the IndustryPack (IP) mezzanine bus, a device used to provide input/output (I/O) capabilities in general-purpose computer systems. IndustryPack is a registered trademark of GreenSpring computers and a specification maintained by the VITA standards organization (VSO) of the American National Standards Institute (ANSI).
IP Cores
Intellectual property (IP) cores are pre-designed, pre-tested, integrated circuits or boards of industry-standard functions that can be easily used in embedded applications. Generally IP cores are treated as intellectual property and are licensed to OEMs.
