When NonStop moved from its MIPS processor-based architecture to Itanium in 2005, it made a dramatic shift away from a design and components that were largely unique to ones that highly leveraged HP's other Integrity products.

This paper explains some basic NonStop concepts and how they're implemented in the current generation of Integrity NonStop systems, the H-Series.
