The ASRock Rack SIENAD8UD3 is a deep Micro-ATX server motherboard for one AMD EPYC 8004 series processor, with eight DDR5 RDIMM slots, two PCIe 5.0/CXL 1.1 x16 slots, and IPMI remote management. It suits builders creating compact, remotely managed servers or workstations that need enterprise-class expansion and memory.
Recommended For
- Storage-server builders creating a compact, single-socket NAS or file server for many SATA drives, especially when they can use MCIO-to-SATA breakout cables and a compatible chassis.
- Edge, retail, or telecom infrastructure teams deploying single-socket EPYC servers where rack space and power use matter and remote IPMI management is useful.
- Infrastructure builders assembling a single-socket server for virtualization or container workloads that need server-class RDIMM memory, PCIe Gen5 expansion, and out-of-band management.
- System integrators building storage or compute nodes around PCIe Gen5 devices, using the board’s MCIO connections for NVMe drives or compatible expansion cabling.
