The ASRock Rack SIENAD8UD-2L2Q is a Deep Micro-ATX server motherboard for single-socket AMD EPYC 8004 builds, combining DDR5 RDIMM support, PCIe 5.0/CXL 1.1 expansion, and dual 25GbE networking for compact compute and virtualization servers.
Recommended For
- Edge, telecom, and branch-infrastructure teams building a single-socket server for deployment near network or operational workloads, where server footprint and power use matter.
- Server builders consolidating virtualization, database, or service-provider workloads on one EPYC 8004 system, with registered DDR5 memory and remote IPMI management.
- Storage and network-appliance builders who need multiple high-speed expansion and storage connections, onboard 25GbE, and out-of-band server management in a compact board layout.
- Technical teams building compact storage or compute servers that need more memory and I/O options than an entry-level server platform, without targeting a larger EPYC 9000-class system.
