The Dell PowerEdge R9815 is the first 18th Generation PowerEdge: a 2U, single-socket rack server built on one 6th Gen AMD EPYC 9006 Series processor with up to 256 cores at up to 600 W, cooled by air as standard. With 16 DDR5 channels (one DIMM per channel, up to 8000 MT/s), all-NVMe E3.S Gen6 front storage, up to four PCIe Gen6 slots and iDRAC10, it consolidates work that used to need dual-socket servers into a single socket.
