Introduction
This paper describes the architecture and implementation of major technologies in the HP Integrity c-Class server blades
based on the Intel® Itanium® processor 9500 series modules. The Integrity server blades architecture opens a chapter in
server scalability by using a common base two-socket (2S) base blade to build four- and eight-socket systems.
HP Integrity Blade Links attach to common base server blades to scale from two (BL860c i4), to four- (BL870c i4) or
eight-socket systems (BL890c i4). See figure 1 for a physical view of the three form factors.
It is assumed that the reader is familiar with HP Integrity server technology and has some knowledge of BladeSystem
architecture. For more information about the infrastructure components and complete specifications of each server
blade, visit hp.com/go/bladesystem.
