The Supermicro X11SRA-RF is an ATX workstation/server motherboard for builders using a compatible Intel Xeon W processor who need ECC memory support, multiple expansion slots, and onboard 5G networking.
Recommended For
- Workstation builders using a supported Xeon W-2100 or W-2200 processor who need ECC memory for professional compute or content-creation workloads.
- Memory-intensive workstation users who need multiple DIMM slots and ECC RDIMM or LRDIMM support for large working sets.
- Workstation or homelab builders who want to manage a system remotely through IPMI, rather than relying only on physical access.
- Compute-focused builders who need room for several PCIe cards, such as graphics or accelerator cards, plus workstation storage options including M.2 and U.2.
