The ASRock Rack B550D4U-2T is a Micro-ATX server motherboard for compatible AMD Ryzen processors, combining two 10GbE ports and dedicated IPMI LAN for compact server builds that need fast networking and remote management.
Recommended For
- Homelab builders running a self-hosted server who want out-of-band IPMI access for remote power control and management, plus dual 10GbE without adding a network card.
- NAS builders with up to six directly attached SATA drives who want a compact AM4 system and 10GbE for moving data across a fast local network.
- Small-business or home-server operators who need a micro-ATX Ryzen server platform with ECC UDIMM support and remote management in a compact case.
- Virtualization and container-host builders who already have a compatible AM4 Ryzen CPU and want server-style remote administration alongside two onboard 10GbE ports.
