About the ASRock Rack EPC621D8A
The ASRock Rack EPC621D8A is an EATX dual-socket server motherboard based on the Intel C621 chipset, supporting Intel Xeon Scalable Processors (first and second generation, Skylake-SP and Cascade Lake-SP) in dual LGA3647 socket configuration. With support for up to 28 cores per socket (56 cores total with Xeon Platinum 8280), it remains a highly relevant platform for enterprise customers running established workloads who require broad software ecosystem compatibility and Intel's RAS feature set.
The board provides 16 DDR4 DIMM slots (8 per CPU) supporting RDIMM and LRDIMM ECC memory up to 2TB total capacity at speeds up to DDR4-2933. Intel Optane DCPMM is supported in AppDirect and Memory Mode across all DIMM slots, enabling persistent memory configurations for database and analytics workloads. PCIe 3.0 expansion includes three full-length x16 slots per CPU plus additional x8 slots from the PCH, accommodating multi-GPU, NVMe, and high-speed NIC expansion.
Onboard connectivity includes dual 10GBase-T via Intel X550, plus the standard ASPEED AST2500 BMC for IPMI 2.0 and Redfish management. The EPC621D8A is a staple platform for VARs building 2U and 4U servers targeting enterprise ERP, Oracle, and SQL Server workloads where Intel platform certification is a procurement requirement.
Ideal for
- Oracle Database and SQL Server enterprise database servers
- SAP ERP application server nodes requiring Intel platform certification
- VMware vSphere clusters with Intel-certified workload requirements
- Two-socket AI training servers with multi-GPU configurations
- Enterprise file and NAS server builds with large DRAM capacity
- Legacy application modernization requiring broad ISV software compatibility
