Packaging and Overview
The motherboard's box and packaging are very similar to that of previous Supermicro server motherboards. It's very basic but gets the job done. The white boxes you see are CPU coolers.
Accessories include six SATA6Gb/s cables, IO shield, quick reference guide, and M.2 mounting hardware.
The X11DAI-Nhas seven 4-pin PWM fan headers, and by default they are in PWM mode, but they can operate DC mode fans. The motherboard has six blue and two black DIMMs per each CPU. The CPU offers six memory channels; the black DIMM allows you to add one DIMM on to two of those channels per CPU.
Both VRM heat sinks are attached to the motherboard, which is different than official pictures. The back of the motherboard has almost no components.
The motherboard's IO panel features a VGA port, four USB 3.0 ports, 7.1 HD audio, two 1Gbit NICs, USB 3.1 type-A, and USB 3.1 type-C.
CPU1 handles two x16 slots and CPU2 handles two x16 slots, so the PCI-E slots are spread among both CPUs.
Eight SATA6Gb/s ports can be found on this motherboard, the two orange ports support SATA DOM, with the power header located right near the two orange ports. A single USB 3.0 type-A port is located on the inside of the motherboard. We also get two NVMe slot connectors and one of the NVMe I2C2 connectors. We also get three T-SGPIO headers in this area.
The motherboard power header and two CPU headers sit in front of the front panel headers. The power SMB header also sits near the 8-pin connector. At the bottom of the motherboard, we find disable jumpers, USB 3.0 internal header, TPM header, and replaceable BIOS socket.
The motherboard also has a COM port and NCSI header. The heat sinks all make good contact with what they cool.
