ATX Server Board for LGA 3647 Xeon

This Supermicro motherboard fits the ATX form factor and uses the Intel C621 chipset to host LGA 3647 Xeon Scalable processors. It targets builders assembling rack or tower servers that need up to 1 TB of DDR4 2666 ECC memory across multiple DIMM slots. The board delivers seven PCIe 3.0 expansion slots, dual Intel I210 1 GbE ports and eight SATA 6.0 Gb/s connectors with RAID 0, 1, 10 and 5 support.

Suits Multi-Slot Servers, Not High-Density 10GbE

The seven PCIe slots make it a good match for installations that require several add-in cards such as RAID controllers, GPU accelerators or extra NICs. Systems that need more than two 1 GbE ports or a greater number of SATA ports will require a different platform. Workloads demanding higher memory speeds than 2666 MHz or a smaller form factor than ATX are also outside this board's design envelope.

1 TB LRDIMM 3DS Maximum Memory Capacity

The decisive specification is the 1 TB ceiling for LRDIMM 3DS modules, alongside 512 GB for standard LRDIMM and 256 GB for RDIMM. This limit defines whether the board can satisfy a given virtualization, database or HPC memory footprint. If the target configuration exceeds 1 TB, another motherboard must be selected.

Soalan tentang produk ini

What PCIe generation do the seven expansion slots use, and how are the lanes divided?

All seven slots are PCIe 3.0; four run at x8, two are x8 wired into x16 connectors, and one is x4 wired into an x8 connector.

What are the board dimensions and form factor, and which mounting holes should line up in a standard chassis?

The board is ATX at 12.0" x 9.6", so it uses the standard ATX mounting pattern found in most server cases.

How is the M.2 module secured, and which keying and lengths does the slot accept?

The M.2 socket takes 2280 and 22110 cards with M-key notches and is retained by a single screw on the board.
