The Supermicro X11SPH-nCTF is a compelling storage-server motherboard if you need native SAS3, SATA, NVMe, dual 10GbE and IPMI in a standard ATX board. It is a single-socket LGA-3647 platform for supported Xeon Scalable processors, but its age and CPU-generation requirements make BIOS, memory, backplane and chassis checks essential before buying.
What the X11SPH-nCTF offers
Supermicro identifies the board as SKU MBD-X11SPH-nCTF, built around Intel’s C622 chipset and one LGA-3647 (Socket P) processor socket. Its ATX dimensions are 12 × 9.6 inches, which can simplify fitting it into a compatible standard-ATX chassis. The manufacturer lists processor support up to 205 W TDP and up to 28 cores. These are specifications, not a guarantee that every processor or cooling arrangement will work in a given system. Supermicro’s product page lists the supported platform details.
Which CPUs and memory are compatible?
CPU generation and BIOS
The board supports listed first- and second-generation Intel Xeon Scalable processors. BIOS version matters for later CPUs: Supermicro specifies BIOS 3.0a or later for second-generation Xeon Scalable SP, and 3.2 or later for second-generation Cascade Lake-R. Check the exact processor generation and stepping against Supermicro’s compatibility information and confirm the installed BIOS before purchasing; do not assume a used board has an up-to-date BIOS.
The published maximum CPU TDP is 205 W. That figure describes processor support, not the expected power draw of a complete server. Confirm that the selected heatsink, socket-retention hardware, chassis airflow and power supply suit the processor and workload.

Memory capacity and speed
There are eight ECC DDR4 DIMM slots supporting RDIMM and LRDIMM, with a stated maximum capacity of 2 TB using 3DS modules. Supermicro lists data rates of 2933, 2666, 2400 and 2133 MT/s; 2933 MT/s is listed only for 82xx/62xx series processors. Actual supported speed and capacity depend on the CPU and memory configuration. Validate module type, capacity, rank and population against the board’s tested memory list rather than treating the maximum as a promise for every combination.
How many drives can it connect?
The board’s built-in storage links are its main attraction. Supermicro specifies eight SAS3 ports at 12 Gbps through a Broadcom 3008 controller and ten SATA3 ports at 6 Gbps through the C622 chipset. The listed RAID modes are 0/1/10 for SAS and 0/1/5/10 for SATA. It also provides two OCuLink PCIe 3.0 x4 NVMe connections and an M.2 2280 M-key socket that supports PCIe 3.0 x4 or SATA.

| Connection | Quantity and interface | Controller or notes |
|---|---|---|
| SAS | 8 × SAS3, 12 Gbps | Broadcom 3008; RAID 0/1/10 listed by Supermicro |
| SATA | 10 × SATA3, 6 Gbps | Intel C622; RAID 0/1/5/10 listed by Supermicro |
| NVMe | 2 × OCuLink, PCIe 3.0 x4 | Confirm cable and backplane lane mapping |
| M.2 | 1 × M-key 2280 | PCIe 3.0 x4 or SATA |
These are motherboard connections, not a guarantee of a particular number of installed drives. Before choosing a chassis or backplane, verify connector type, cable, lane mapping, drive form factor and backplane compatibility. A SAS expander can extend the SAS topology, including to an external disk shelf, but the expander, cabling and enclosure must be selected as part of the system design. ServeTheHome also notes two SATA DOM-capable ports and internal USB boot options in its review.
Expansion, networking and remote management
Expansion and bandwidth
ServeTheHome describes four PCIe slots and M.2 expansion. It also discusses the possibility of a shared PCH bandwidth bottleneck if many devices attached through the chipset are saturated at once; the reviewer considered the board’s additional PCIe x8 connection to the PCH appropriate for likely workloads. That is design analysis from the review, not a universal performance guarantee. Map the devices you intend to run and consider whether they will be busy simultaneously.
Recommended Free Tools
Ethernet and IPMI
For network connectivity, Supermicro specifies two RJ45 10GBase-T ports using Intel X722 and X557 controllers. The board also has an ASPEED AST2500 BMC, VGA output and IPMI 2.0/KVM management features with a dedicated LAN. ServeTheHome reported HTML5 iKVM, remote console and Redfish support in its review-era context. Firmware interfaces and feature or licensing details can change, so confirm the current firmware and any licensing requirements for the remote-management workflow you need, especially remote BIOS updates.
What the 2017 review tested—and what it did not
Patrick Kennedy’s ServeTheHome review, published August 10, 2017, called the board a solid single-socket 10GBase-T storage-server platform. Its test system used a Xeon Silver 4114, six 16 GB DDR4-2400 Micron RDIMMs, an Intel DC S3710 400 GB SSD and a Supermicro 32 GB SATADOM. The reviewer said several Xeon models had been installed in the lab and praised the socket mechanics, but explicitly did not test a 205 W Xeon Platinum 8180. The review therefore does not establish performance for every supported CPU or configuration. Read the ServeTheHome review.
Rank #4
- 3Dconnexion Supermicro X10drh-it-b - Dual LGA2011 Intel C612 Chipset EATX Server Motherboard, Support DDR4, USB3.0, VGA
ServeTheHome measured power on 208 V data-center power at 17.1 °C and 70% relative humidity. With the Xeon Silver 4114 test build, which included two SSDs and six DDR4-2400 DIMMs, it reported 6.1 W with BMC only, 63.2 W at OS idle and 110.3 W under a GROMACS AVX-512 load. These are measurements of that particular build under those conditions, not expected figures for other systems. CPU TDP is not whole-system power consumption.
The outlet’s 2017 scores were 9.4 for design and aesthetics, 9.8 for performance, 10 for feature set, 9.3 for value and 9.6 overall. These are historical review scores, not current comparative results. Kennedy’s conclusion was: “If you are looking for a single socket 10Gbase-T storage server, this is going to be a solid platform.”
Who should consider this board?
The X11SPH-nCTF is a good fit when a build benefits from several native storage interfaces, onboard 10GBase-T and remote management, and the chosen Xeon generation remains suitable for the workload. It is less straightforward if the system depends on a newer processor, a particular backplane, an SFP+ network, or a compact chassis; those requirements need checking before the board is selected.
When comparing it with another server board, assess the CPU generation and lifecycle, native storage links and backplane wiring, network port type, memory capacity and population, chassis dimensions, remote-management needs, and total platform cost in your market today. ServeTheHome mentions the related X11SPH-nCTPF as a variant with SFP+ cages in place of RJ45; confirm the details in product documentation before comparing the two directly. The 2017 review’s street-price observation is not a current price guide.
Quick Recap
Pre-purchase compatibility checklist
- Match the exact Xeon model and generation to the board’s support information and installed BIOS version.
- Check ECC DDR4 RDIMM or LRDIMM compatibility, the desired capacity, and the validated population and speed for the chosen CPU.
- Confirm heatsink retention, processor cooling and chassis airflow for the CPU’s power requirements.
- Verify that the chassis accepts a 12 × 9.6-inch ATX board and that its backplane and cables match the SAS, SATA or OCuLink connections you plan to use.
- Review Supermicro’s chassis compatibility and tested-component resources for the exact build. If buying a used board, confirm the MBD-X11SPH-nCTF SKU, included I/O shield and cables, seller condition and return terms.
