Caution: This is an EA (early available) engineering manual. The contents may not accurately reflect the actual or final version of this product.
ADLINK COM-HPC-ALT is a COM-HPC® Server Type Size E compliance module featuring Ampere® Altra® Series SoC. It supports up to 128 cores and
boosts up to 2.6GHz based on 190W TDP while providing up to 384GB of RDIMM, UDIMM, LRDIMM DDR4 six-channel memory at up to 3200 MT/s in 6
DIMM sockets. These combined features make the COM-HPC-ALT well suited to customers who need uncompromising system performance and
responsiveness embedded solutions with extended product life.
The COM-HPC-ALT features 4x 110G SFP+ interfaces by Broadcom BCM57502 (PCIex8 input, 4x 10G-KR output) and a single on-board Gigabit Ethernet
port by Intel i210/i211 series. It features 64x PCIe Gen4 physical lanes, 4x USB 3.x upgrade signals, and 4x USB 2.0 ports
The COM-HPC-ALT features 1x GPP_SPI and 1x Boot_SPI, 1x SMBus, 2x I2C, 2x UART and 12x GPIO. No eSPI offered
The COM-HPC-ALT based discrete circuit and MMC (ATMEGA128), instead of CLPD, are supported by the module for power sequence control
The COM-HPC-ALT supports IPMB, which supports an MMC (module management controller, ATMEGA) and its firmware on the module. Combined
with a dedicate 1x PCIe lane (it is called PCIe_BMC), IPMB can enable Carrier BMC (for example, AST2500 or equivalent) and access necessary message
(for example, voltage information and CPU temperature on module) between MMC and Carrier BMC. In addition, an EEPROM is located on I2C_0 bus as
a traditional COMe EEPROM usage and also as a FRU for Carrier BMC
One security chip is supported on the module. The traditional TPM 2.0, SPI based (same as Ampere Altra reference design) (it is on GP_SPI bus)
The module is equipped with EDK2 (bootloader, open source) BIOS with CMOS backup, supporting embedded features such as remote console,
hardware monitor, and watchdog timer.
