AsRock SPC621D8U-2T Micro-ATX Server Motherboard
Overview
The AsRock SPC621D8U-2T is a single-socket LGA 4189 (Socket-P+) micro-ATX server motherboard built for rack-mount and tower server chassis where you need dual integrated 10GbE and a compact footprint that still fits standard micro-ATX server enclosures. At 11.89 x 11.14 in, SPC621D8U-2T (often searched as SPC621D8U 2T) slots into micro-ATX server chassis without the extended depth of an E-ATX board, which matters when you're working with 2U or 3U rack enclosures that have tight motherboard tray clearance. This is a bare motherboard purchase — the buyer supplies a compatible 3rd Gen Intel Xeon Scalable processor, DDR4 memory, and a chassis with matching I/O shield and standoff layout.
Key Features
- Single Socket P+ (LGA 4189): supports 3rd Gen Intel Xeon Scalable processors — the right platform when a workload needs single-socket server-class reliability (ECC memory support, server chipset feature set) without the cost and power draw of a dual-socket board.
- Micro-ATX form factor (11.89 x 11.14 in): fits into more compact 2U/3U rack chassis than full-size E-ATX server boards, useful when rack space or chassis selection is constrained on a build-out.
- Dual onboard 10GbE: two 10 Gigabit Ethernet ports built into the board mean no separate NIC card is needed for high-throughput uplinks — frees a PCIe slot for storage controllers, GPUs, or capture cards instead of network expansion.
- 3.31 lb board weight: worth noting for chassis weight budgets and shipping calculations on multi-unit rack builds.
- 2.76 in height profile: relevant when checking clearance against chassis standoffs, drive cages, and cable routing in shallow rack units.
Integration & Compatibility
Because SPC621D8U-2T is a bare server motherboard, plan the rest of the build around it: a 3rd Gen Intel Xeon Scalable CPU rated for Socket P+ (LGA 4189), registered/ECC DDR4 memory compatible with the platform, and a chassis sized for micro-ATX server boards with adequate airflow for a server-class CPU. The dual 10GbE onboard ports make this board a reasonable fit for network video recorders or VMS server builds handling multiple high-bitrate camera streams, where sustained network throughput to storage matters more than raw port count. If you're scoping a broader server refresh, review a VMS architecture guide before finalizing CPU and memory selection to make sure the platform matches your camera count and retention targets. Pair the finished build with a PoE switch sized to your camera load, and check the AsRock server board lineup for higher-port-count or dual-socket alternatives if this workload outgrows a single-socket platform.
Frequently Asked Questions
Q: What CPU socket does the SPC621D8U-2T use?
A: Single Socket P+ (LGA 4189), supporting 3rd Gen Intel Xeon Scalable processors.
Q: What form factor is the SPC621D8U-2T?
A: Micro-ATX, measuring 11.89 x 11.14 x 2.76 in and weighing 3.31 lb.
Q: Does the SPC621D8U-2T include onboard networking?
A: Yes, it includes dual onboard 10GbE ports.
Q: Does the SPC621D8U-2T come with a CPU or memory included?
A: No, this is a bare motherboard — CPU, memory, and chassis are sourced separately and must match the LGA 4189 platform requirements.
The SPC621D8U-2T is what you spec when a single-socket LGA 4189 build needs to fit a micro-ATX rack chassis instead of full-size E-ATX — the 11.89 x 11.14 in footprint is the whole reason to pick this board over AsRock's larger single-socket options.
Technical Highlights:
- Socket P+ (LGA 4189): single-socket 3rd Gen Xeon Scalable support gives you server-class ECC memory and platform reliability without dual-socket power and cost.
- Dual 10GbE onboard: two 10GbE ports free up a PCIe slot that would otherwise go to a NIC card — useful headroom for a RAID controller or capture card on a VMS server build.
- 2.76 in height / 3.31 lb: confirm this against your chassis standoff and drive cage clearance before ordering, especially in shallow 2U enclosures.
Deployment Considerations:
- This is a bare board — budget separately for a compatible Xeon Scalable CPU, ECC DDR4, and a chassis with the correct I/O shield cutout for SPC621D8U-2T.
- Dual onboard 10GbE is a strong fit if your storage or camera-stream throughput already saturates 1GbE, but it's dead weight if your network core hasn't been upgraded to match — check switch-side 10GbE port availability before committing.
Best fit: a single-socket VMS or NVR server build going into a compact 2U/3U rack chassis where dual 10GbE uplinks to storage matter more than multi-socket CPU headroom.
