Supermicro X11SPM-TPF Rev 2 Topology
Since this is an Intel Xeon Scalable single-socket system, the topology is very straightforward. There is a single NUMA domain:
One item we wanted to point out is that the onboard SFP+ networking is being provided by the Intel C622 PCH. Those are the two network adapter references at the bottom of this diagram.
Supermicro likewise has other versions of the motherboard that contain different features. For example, the X11SPM-TF is a 10Gbase-T variant of this platform which uses the Intel X557-AT2 for the PHY instead of the Inphi CS4227. The X11SPM-F uses the lower-cost Intel C621 PCH since it does not have 10GbE capabilities. Those three variants give different options to those who may be looking for different networking than we reviewed here.
At just under $400 street price, the Supermicro X11SPM-TPF is a platform that should give several of our readers pause. That is only about $50 more than the least expensive 1GbE Intel Xeon Scalable motherboards on the market today. That $50 buys dual 10GbE networking which is a vast improvement over 1GbE. It is hard to add a new dual SFP+ adapter for $50 which needs to be a consideration.
With the mATX form factor, one trades a few features for compactness. For example, there are fewer PCIe and DIMM slots than we may see on larger motherboards. We also would have liked to see a second M.2 slot onboard. Reducing the longest dimension of the motherboard from 12 inches to 9.6 inches means that there is more room in compact chassis. It also means a larger set of chassis are available to the platform than a full ATX motherboard would have access to.
Overall, this is a great platform for those who are buying in the Intel Xeon Bronze, Silver, or low to midrange Gold processors. The system follows this generation of Intel platform closely which means it will likely be well supported for some time. While Supermicro did not take many risks aside from the size, delivering a solid and low-cost platform is still a great result.
