1-2 System Overview
Built upon the functionality and the capability of the Intel 5500/5600 Series Pro-
cessors and Intel 5520 chipset, the X8DTG-QF motherboard provides the perfor-
mance and feature set required for dual-processor-based 4U servers optimized
for High Performance Computing (HPC)/Cluster platforms. The Intel 5520 platform
consists of the 5500/5600 Series (LGA 1366) processor, the 5520 (IOH-36D), and
the ICH10R (South Bridge). With the Intel QuickPath interconnect (QPI) controller
built in, the 5500/5600 Series Processor is the fi rst dual-processor platform that
offers the next generation point-to-point system interconnect, replacing the current
Front Side Bus Technology, substantially enhancing system performance by utiliz-
ing serial link interconnections with increased bandwidth and scalability.
The IOH connects to each processor through an independent QPI (QuickPath
interconnect) link. Each link consists of 20 pairs of unidirectional differential lanes
for transmission and receiving in addition to a differential forwarded clock. A full-
width QPI link pair provides 84 signals. Each processor supports two QuickPath
links, one going to the other processor, and the other to the 5520 chips.
The 5520 chipset supports PCI Express Gen2 lanes peer-to-peer read and write
transactions. The ICH10R provides multiple PCI-Express SATA and USB con-
nections.
In addition, the 5520 platform also offers a wide range of RAS (Reliability, Avail-
ability and Serviceability) features. These features include memory interface ECC,
x4/x8 Single Device Data Correction (SDDC), Cyclic Redundancy Check (CRC),
parity protection, out-of-band register access via SMBus, memory mirroring,
memory sparing, and Hot-plug support on the PCI-Express Interface.
