The ASRock Rack EPYC3451D4U-2L2T2O8R is a Micro-ATX server motherboard with an AMD EPYC Embedded 3451 processor, four ECC-capable DDR4 memory slots, and a mix of 10GbE and 1GbE networking. It suits compact servers that need integrated processing, memory reliability, and multiple high-speed network connections.
Recommended For
- Small-business and edge-server builders who want a compact, single-board platform for several network services, with out-of-band management and multiple 10GbE connections.
- Virtualization and homelab builders who need a server platform for multiple VMs or services, plus ECC memory, IPMI, and room for network or storage expansion.
- Storage-server builders connecting SAS or SATA drives alongside U.2 NVMe storage, who can plan around the board’s lane-sharing and cabling requirements.
- Compact server builders who want an integrated 16-core EPYC Embedded platform rather than selecting and installing a separate processor.
