LOADING...

The ASRock Rack SPC621D8-2L2T is an ATX single-socket server motherboard for system builders using 3rd Gen Intel Xeon Scalable processors, with remote IPMI management, four 10GbE/1GbE network ports, and seven PCIe 4.0 slots for server and infrastructure builds.

Recommended For

  • Server and workstation builders running a compatible 3rd Gen Intel Xeon Scalable processor who need an ATX platform with IPMI for remote monitoring and management.
  • Workstation or compute-system builders who need several PCIe slots for multiple accelerator, networking, or storage cards; slot widths change when adjacent slots are occupied.
  • Network or storage server builders who want two onboard 10GbE ports, two 1GbE ports, IPMI management, and SATA connections without adding separate network cards.
  • Virtualization and data-processing builders who need a single-socket Xeon platform with registered-memory support and room for PCIe expansion.

Real-World Use Scenarios

  • For a workstation running multithreaded engineering, rendering, or other data-heavy applications, pair the board with a compatible Xeon Scalable processor and registered memory; it provides a workstation-oriented platform, while actual performance depends on the chosen components and workload.
  • For a storage server or NAS moving large files across a 10GbE network, connect it to a suitably fast switch and storage system; Hardwareluxx measured transfers up to 9.8 Gbit/s, noting that both the sender and receiver must keep up to approach that rate.
  • For a virtualization host consolidating several server or lab workloads, use a compatible Xeon processor and supported registered memory; IPMI also lets an administrator monitor and manage the system remotely without relying on a local display and keyboard.
  • For a workstation or server that needs several add-in cards—such as graphics, storage, or networking cards—the board offers multiple PCIe slots; check the slot layout before building, because using certain adjacent slots switches some x16 slots to x8 operation.
  • For a server that needs several directly connected SATA drives, use the board’s onboard storage connections for a compact build; it can support a multi-drive setup without requiring a separate storage controller for every drive, subject to the case, cabling, and storage configuration.
