1.1 System Overview
Oracle’s Sun Server X2-4 is a 3 rack unit (RU) rackmount server that uses the Intel
Xeon E7 platform. This section describes the major features, components, and
capabilities of the server.
1.1.1 Intel Xeon E7 Platform
The Intel Xeon E7 platform is based on the Intel Xeon Processor E7-4800 Series and
uses the Intel 7500 Chipset I/O hub (IOH) as its primary chipset. The platform uses
the Intel QuickPath Interface (QPI), a high-speed, differentially signaled,
point-to-point interface that forms a communication fabric among the processors
(CPUs) and IOHs in the system.
The Sun Server X2-4 uses two Intel 7500 Chipset I/O hubs, each connected to two of
the four CPUs. One of these I/O hubs is designated the legacy I/O hub and has a
connection to the Intel I/O Controller Hub 10 (ICH10) southbridge component.
