The MSI S4051D270RAU6-X2 is a 2U rackmount that is actually home to two independent server nodes. Each node supports an AMD EPYC 9005 processor, up to 2TB of memory, two M.2 drives, six U.2 drives, a half-length PCIe slot, and an OCP network adapter. They have their own I/O connectivity on the front as well: two USB ports, an RJ45 for remote management, and DisplayPort output in case local management is needed. A pair of high-wattage, redundant power supplies handles both systems.
