Supermicro X11SPM-TPF vs ASRock SPC621D8-2L2T Server Motherboard

Buy the ASRock SPC621D8-2L2T for a new build on 3rd Gen Xeon Scalable: it takes 300W chips, eight-channel DDR4-3200, has dual 10GbE onboard and a full ATX layout. Buy the Supermicro X11SPM-TPF only if you already own a 1st or 2nd Gen Scalable CPU and need a compact microATX board with 12 SATA ports. The ASRock is the newer platform with more I/O built in; the Supermicro is older, smaller and leans on SFP+ networking and a large SATA count.

  • Choose the Supermicro X11SPM-TPF if you have a 1st or 2nd Gen Xeon Scalable chip, need a 9.6-inch microATX board, and want 12 SATA ports plus SFP+ networking without add-in cards.
  • Choose the ASRock SPC621D8-2L2T if you are building on a 3rd Gen Xeon Scalable CPU and want eight memory channels, dual 10GbE and a 300W socket in a standard ATX case.

Questions and answers

Which is better for a storage server?
The Supermicro X11SPM-TPF has 12 SATA3 ports against the ASRock's 8, so it drives more drives without a controller card. The ASRock adds RAID 0/1/5/10 and SAS support, so pick it if you want hardware RAID levels or SAS drives.
Can I use the same CPU in both?
No. The Supermicro takes LGA-3647 chips (1st and 2nd Gen Xeon Scalable); the ASRock takes LGA-4189 3rd Gen Scalable only. The CPUs are not interchangeable.
Which has better networking?
The ASRock, with dual 10GbE RJ45 and dual 1GbE RJ45 onboard. The Supermicro has two SFP+ ports and no copper Ethernet, so you need fiber or a transceiver for 10GbE and an add-in card for 1GbE.
Is the ASRock worth stepping up to?
Yes for a new build. It gives a newer socket, 300W CPU support, eight memory channels at DDR4-3200 and built-in 10GbE. Step up only if you are not reusing an older LGA-3647 CPU.
Which fits a smaller case?
The Supermicro, at 9.6 x 9.6 inches microATX. The ASRock is full ATX at 12 x 9.6 inches and needs a standard ATX chassis.
Which holds more memory?
The Supermicro lists up to 1.5TB across 6 DIMM slots. The ASRock has 8 slots at DDR4-3200 but does not state a maximum in its specs, so check ASRock's memory list for your DIMM capacity.
