This is the Dell H28RR (0H28RR) system board for the Dell EMC PowerEdge R640 1U rack server. It has two FCLGA3647 processor sockets and is built on the Intel C620 Series chipset. It supports 1st and 2nd Generation Intel Xeon Scalable processors, including Bronze, Silver, Gold and Platinum models.
The board has 24 DDR4 ECC DIMM slots for RDIMM, LRDIMM and NVDIMM-N memory. It includes Dell iDRAC9 with Lifecycle Controller for remote management and embedded PERC S140 software RAID. A dedicated Mini-PERC slot and support for Dell BOSS boot storage are also included.
Expansion is PCIe Gen3 through Dell riser assemblies. The board is designed specifically for the PowerEdge R640, and compatibility should be checked against the server's service tag, processor generation, memory configuration, BIOS revision and installed hardware.
