COM-HPC-sIDH User’s Guide PICMG COM-HPC R1.1

1. Introduction

The COM-HPC-sIDH is a Server Type COM-HPC Size D module based on Intel® Xeon® D-2700 processors (formerly “Ice Lake-D HCC”). The processor

puts an emphasis on longevity and industrial-class reliability, offers up to 20 cores at 3.1GHz boost frequency, and features AVX512-VNNI (Vector

Neural Network Instructions) that deliver accelerated AI inferencing performance. Typical industries in need of such high performance, low power

characteristics include industrial automation and control, medical ultra sound, image processing and analysis, high-speed video encoding and streaming,

predictive traffic analysis, and multi-camera-based AI.

The COM-HPC-sIDH has up to four DIMM sockets supporting up to 256GB (4x 64GB) of DDR4 RDIMM memory, or even higher with LRDIMM. It

provides a memory frequency of up to 3200 MT/s, dependent on system configuration.

Selected SKUs features industrial class reliability with extended temperature range operability. Combined with ultra-low latency-focused Intel® Time

Coordinated Computing (Intel® TCC) technology, COM-HPC-sIDH is well suited for mission critical, hard real-time, and rugged solutions.

The integrated high speed Ethernet controller inside Intel® Xeon® D-2700 processors provides up to 8x 10G networking with selected PHY on carrier

for SFP+ or 10GBASE-T feature, or 4x 25G based on selected PHY on carrier for SFP+, or 10G/25G in KR backplane usage and even up to 40G/50G/100G

(TBC) in KR backplane usage. It also includes an onboard 2.5Gigabit Ethernet port with optional Time Sensitive Network (TSN) support.

An optional IPMB via MMC (module management controller, located on module) and a dedicated PCIe lane (PCIe_BMC) are also offered. By connecting

these IPMB, dedicated PCIe lane and other management buses, such as eSPI, UART, to the carrier board BMC (for example, AST2500), it allows for out-

of-band management.

Inputs/outputs provided include up to two PCIe Gen4 x16 and another two PCIe Gen3 x8 lanes that can be used for AI accelerator and NVMe SSD, four

USB 3.0/2.0 ports, two SATA 6Gb/s ports, and 12x GPIO pins. TPM chip is equipped for security-related usage. Optional onboard eMMC is offered by

project basis. Support for SMBus, two I2C. is also available The module is equipped with SPI AMI EFI BIOS with CMOS backup, supporting embedded

features such as remote console, hardware monitor, and watchdog timer.
