The MSI S4051D270RAU3-X4 is a 2U rackmount that is actually home to four independent server nodes. Each node supports an AMD EPYC 9005 processor, up to 2TB of memory, two M.2 drives, three U.2 drives, and an OCP network adapter. They all have their own I/O connectivity on the front: 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 all four systems.
