Micro-ATX Xeon server board

The ASRock Rack SPC621D8U-2T is a Micro-ATX motherboard built for single-socket servers using 3rd Gen Intel Xeon Scalable processors in an LGA 4189 socket. It runs on the Intel C621A chipset and fits a standard 9.6 by 9.6 inch footprint.

Suits dense storage and 10GbE needs

This board suits builders who need eleven SATA 6.0Gb/s ports with RAID 0, 1, 5, 10 and a single M.2 2280 slot that accepts PCIe 3.0 x4 or SATA drives. Dual 10GbE ports from the Intel X710-AT2 handle high-throughput networking. Buyers who need more than one processor or more than one M.2 device should look elsewhere.

Four PCIe 4.0 x16 slots for expansion

Four full-length PCIe 4.0 x16 slots provide room for GPU compute, storage controllers or networking cards. Eight DDR4 3200 DIMM slots support RDIMM, LRDIMM and 3DS modules plus Intel Optane persistent memory. The Aspeed AST2500 handles IPMI remote management and video output through a DB15 port. A 4-pin HDD power connector is included for 12V DC-in configurations.

Questions about this item

What CPU socket and generation does the SPC621D8U-2T require?

The board uses the LGA 4189 socket and supports 3rd Gen Intel Xeon Scalable processors, with a single CPU configuration.

Will the four PCIe 4.0 x16 slots and the M.2 slot work with older PCIe 3.0 cards and SATA M.2 drives?

Yes, the PCIe 4.0 x16 slots are backward compatible with PCIe 3.0 cards, and the M-key M.2 slot accepts both PCIe 3.0 x4 and SATA 6Gb/s 2280 drives.

How can I confirm the board is operating correctly after assembly?

Check the Aspeed AST2500 IPMI interface for system health, verify the Intel X710-AT2 10GbE ports show link activity, and confirm the system panel LEDs indicate power and drive status.
