ASRock Rack SPC621D8 Server Motherboard vs Supermicro X11SPM-TPF

These are server boards for different generations of Intel Xeon Scalable. The ASRock Rack SPC621D8 is the newer platform: Socket P+ (LGA 4189) for 3rd Gen Xeon Scalable, PCIe 4.0, eight DIMM slots, and 13 SATA ports. The Supermicro X11SPM-TPF is an older LGA-3647 board for 1st and 2nd Gen Xeon Scalable, with PCIe 3.0, six DIMM slots, and 10GbE SFP+ onboard. Pick the ASRock for a new build with current Xeons and fast NVMe; pick the Supermicro for a compact microATX build or if you already own a compatible 1st or 2nd Gen chip. Both are bare server boards with IPMI and no consumer features.

  • Choose the ASRock Rack SPC621D8 if you are building around a 3rd Gen Xeon Scalable and want PCIe 4.0, eight DIMM slots and lots of SATA in a full ATX case.
  • Choose the Supermicro X11SPM-TPF if you need a smaller microATX board, already have a 1st or 2nd Gen Xeon Scalable, or want 10GbE SFP+ networking built in.

What reviewers say

ASRock Rack SPC621D8 Server Motherboard

Owner feedback on this board is limited, but server builders generally rate ASRock Rack boards as solid value with working IPMI. The common complaints are the narrow 1GbE networking and the cost of the LGA 4189 platform around it.

What people mention
  • ExpansionPraisedOwners like the four x16 and three x8 PCIe 4.0 slots for cards and drives.
  • NetworkingCriticisedBuyers note the two 1GbE ports are basic for a server board and often add a 10GbE card.
  • Remote managementPraisedThe AST2500 BMC with IPMI is reported to work for headless setup and control.
  • Platform costMixedThe board itself is seen as good value, but Xeon chips and LGA 4189 coolers add up.

Questions and answers

Which is better for a new virtualization host?
The ASRock SPC621D8. It takes 3rd Gen Xeon Scalable with more cores, has eight DIMM slots for more RAM, and PCIe 4.0 for fast NVMe. The Supermicro is limited to older CPUs and PCIe 3.0.
Can I use a 3rd Gen Xeon Scalable in the Supermicro board?
No. The X11SPM-TPF uses LGA 3647 and supports 1st and 2nd Gen Xeon Scalable. 3rd Gen chips need LGA 4189, which is the ASRock board's socket.
Which has better networking?
The Supermicro, with two 10GbE SFP+ ports built in. The ASRock has only two 1GbE RJ45 ports, so you would add a PCIe network card for 10GbE.
Which fits a smaller case?
The Supermicro. It is microATX at 9.6 x 9.6 inches. The ASRock is full ATX at 12 x 9.6 inches and needs a standard ATX chassis.
Is the Supermicro worth stepping up to over the ASRock?
Only if you need its smaller size, built-in 10GbE, or already own a compatible 1st or 2nd Gen Xeon. On CPU generation, memory capacity and PCIe speed, the ASRock is the newer and more expandable board.
Do both support IPMI remote management?
Yes. Both have an ASPEED baseboard controller with IPMI, so you can manage the server remotely without a monitor attached.
