Dual LGA 4189 server board for 3rd Gen Xeon
The ASRock Rack SP2C621D16-2T is an EEB form-factor motherboard built around the Intel C621A chipset. It accepts two 3rd Gen Intel Xeon Scalable processors in LGA 4189 sockets and provides sixteen DDR4 3200 DIMM slots in a 1DPC layout. Five PCIe 4.0 x16 slots and one x8 slot deliver high-bandwidth expansion for compute accelerators or networking cards. Dual 10 GbE ports driven by an Intel X550-AT2 controller handle heavy data traffic.
Suited for dense virtualization and storage nodes
This board targets builders who need dual-socket performance with abundant memory capacity and fast networking. The fourteen SATA 6.0 Gb/s ports and two SlimSAS connectors support large drive arrays without add-in HBAs. Buyers who require more than one M.2 device or who need integrated Wi-Fi should look at alternative platforms. Systems that must fit in standard ATX chassis cannot use the 12 x 13 inch EEB outline.
Sixteen DDR4 3200 slots in 1DPC configuration
Memory capacity tops out at sixteen modules running at 3200 MT/s, with each channel populated by a single DIMM for signal integrity. RDIMM, LRDIMM and Intel Optane persistent memory are all supported. This density decides whether the platform can hold the working set for in-memory databases or large VM fleets.

Küsimused selle toote kohta
Should I populate all 16 DDR4 3200 slots or start with fewer modules?
The board has 8+8 DIMM slots running 1DPC, so each slot connects directly to a memory controller. Filling all 16 slots gives maximum capacity and bandwidth, but you can start with a smaller matched set per CPU and add later.
What does the dual LGA 4189 layout mean for actual throughput?
Two sockets each drive their own PCIe 4.0 lanes — five x16 slots and one x8 slot split between the CPUs — so GPU, storage or networking cards can run at full Gen 4 speed without sharing bandwidth across sockets.
How fast are the onboard 10GbE ports in practice?
The Intel X550-AT2 controller provides two RJ45 ports at 10 Gbps line rate, so sustained throughput approaches 10 Gbps per port with compatible cabling and switch partners.
