Server board for Xeon Scalable and W-3300 CPUs

The Supermicro MBD-X12SPA-TF-O is an extended ATX server motherboard built around the Intel C621A chipset and LGA 4189 socket. It targets system integrators and data-centre operators deploying 3rd Gen Intel Xeon Scalable or Xeon W-3300 processors with TDPs up to 270 W. The platform delivers sixteen DDR4 slots and four full-length PCI Express 4.0 x16 expansion slots in a single-socket layout.

Sixteen DDR4 slots supporting 4 TB capacity

Memory scale is the decisive specification: sixteen 288-pin slots accept DDR4-3200 ECC RDIMM or LRDIMM modules up to a combined 4 TB. The board also supports Intel Optane persistent memory at the same speed and capacity limit. Builders needing more than 4 TB of system memory or a different memory generation must choose another platform.

IPMI LAN plus dual 10 GbE and 1 GbE ports

Rear I/O includes a dedicated IPMI RJ45 port driven by a Realtek RTL8211F PHY, one 10GBase-T port from the Marvell AQC113 controller, and one gigabit port from the Intel I210-AT controller. Aspeed AST2500 graphics provide basic video output. Storage connectivity comprises eight SATA 6 Gb/s ports with RAID 0, 1, 5, 10 and four M.2 slots (PCIe 4.0 x4, M-key, 2260/2280/22110) that also support RAID when a VROC key is installed.

Questions sur cet article

How does the 4 TB maximum memory capacity translate when all 16 DDR4 3200 slots are populated?

Filling all 16 slots with 3DS ECC RDIMMs or LRDIMMs at DDR4-3200 reaches the 4 TB limit; Intel Optane persistent memory modules are also supported in the same slots up to the same 4 TB ceiling.

What does the four PCIe 4.0 x4 M.2 interfaces cap at for storage RAID, and what extra item is needed?

The four M.2 slots run at PCIe 4.0 x4 each and support RAID 0, 1, 5 and 10, but a VROC key must be installed to enable hardware RAID across them.

What chassis clearance and mounting pattern does the Extended ATX form factor require?

The board follows the Extended ATX (E-ATX) footprint, so the case must provide matching standoff positions and enough depth for the larger PCB; standard ATX holes alone will not align.
