IntelP®P Server Board S3420GP TPS Functional Architecture
3 nct. Fu ional Architecture

The architecture and design of the Intel® Server Board S3420GP is based on the Intel® 3420

Chipset. The chipset is designed for systems based on the Intel® Xeon® processor in the FC-

LGA 1156 socket package. The chipset contains two main components:

Intel 3420 Chipset
PCI Express* switch (Intel
®
® Server Board S3420GPLX only).

This chapter provides a high-level description of the functionality associated with each chipset

component and the architectural blocks that make up the server board.
