SOM-5991 User Manual 2
1.1 Introduction
SOM-5991, designed around the Intel® Xeon® Processor D-1500 family, brings the
performance and advanced intelligence of Intel® Xeon® processors into a dense,
low-power system-on-a-chip. With enhanced reliability, availability, and serviceability
features; platform storage extensions; and built-in hardware virtualization; the Intel®
Xeon® processor D-1500 product family offers new options for optimizing a variety of
workloads and infrastructure for midrange routers, network appliances, security
appliances, wireless base stations, embedded midrange IoT devices, entry network-
ing, midrange storage area networks (SANs), network attached storage (NAS) appli-
ances, warm cloud storage, and more.
In a breakthrough move, the SOM-5991 incorporates two 10GBase-KR interfaces,
which should help fulfill the ever-increasing service application demands in the area
of COM Express. Customers can take advantage of SOM-5991's native 10GBase-
KR interfaces to design in 10GbE carrier boards. SOM-5991 and its development
board are ready for customers as a reference design.
PCIe x16 and 8 PCIe x1 support Non-Transparent Bridge (NTB), which allows redun-
dancy via PCIe. This helps reduce data loss, allowing a secondary system to take
over PCIe storage devices if the CPU fails, and it provides high availability for appli-
cations providing continuous service.
SOM-5991 has four screw holes near the CPU, positioned in compliance with the
Intel® standard thermal design guide. The thermal module is attached to the CPU
using a balanced torque design, it is the first COM Express with added a backplane
to increase rigidity so the thermal module makes tight contact with the CPU without
board bending. This results in highly efficient heat dissipation with outstanding com-
puting performance. Advantech also offers a SOM-5991 pre-assembly thermal solu-
tion service that can make system-level assembly easier.
