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.
