The ASRock Rack EPYC3251D4I-2T is a 6.7-inch Mini-ITX server motherboard with an integrated 8-core, 16-thread AMD EPYC 3251 SoC, dual 10GbE, and dedicated IPMI LAN. It suits compact server builds that need remote management and fast wired networking.
Recommended For
- Homelab and small-office operators building a compact virtualization host for a handful of VMs, who want ECC memory, dual 10GbE, and remote management in a Mini-ITX system.
- NAS or backup-server builders who need a compact server platform with ECC support, two onboard 10GbE ports, and storage connected through SATA and OCuLink.
- Edge-server and network-appliance builders who want a small system for services such as a gateway, domain controller, or other always-on infrastructure, with dedicated IPMI access for remote administration.
- Small-system builders who need a server board that can use either ATX power or a 12V DC input, such as for a compact enclosure or a DC-powered deployment.
