Supermicro MBD-X11DAi-N

Supermicro MBD-X11DAi-N is an E-ATX server motherboard designed to handle complex computing workloads. With its support for dual Intel Xeon Scalable processors and all-round expansion ports and slots, you can configure a powerful server system for use in data centers that helps you stay ahead of the competition.


Double the Power

Bring unparalleled computing capability to your system by installing two 2nd generation Intel Xeon Scalable processors (Cascade Lake-SP) with this motherboard's dual socket P (LGA 3647). Enjoy superb system performance, efficient power management, and a rich feature set based on cutting edge technologies to address the needs of next-generation users.

Farewell to Memory Insufficiency

High server workload is great to grow your business. But heavy traffic puts an exacting demand on your hardware. Designed with that in mind, this server motherboard is ready to take huge-capacity memory with its 16 DIMM memory slots. You can install up to 4 TB 3DS ECC RDIMM, or up to 4TB 3DS ECC LRDIMM, or up to 2TB Intel Optane DC Persistent Memory.

Optane DC Persistent Memory Modules technology offers data persistence with higher capacity than existing memory modules and lower latency than NVMe SSDs. It provides hyperspeed storage capability for high performance computing platforms with flexible configuration options.

Expand for Brilliance

With four PCI-E 3.0 x16 slots and two PCI-E 3.0 x8 slots, you can add the hardware needed for high-performance computing.

Future Ready Storage

In addition to 10 SATA3 (6 Gbps) ports that support RAID 0,1,5,10, the motherboard also features a M.2 slot, letting you install super-fast PCI-E 3.0 x4 solid state-drive in 2260, 2280, or 22110 form factor.
