The MSI S4056X171RAU12 is a 2U rackmount server offering CPU compute with expansive built-in storage capabilities. It utilizes an AMD EPYC 9005 Series processor, which supports a massive 128 PCI-Express Gen 5 lanes as well as 12 DDR5 memory channels - ensuring plenty of bandwidth and connectivity for various networking options and a host of NVMe solid-state drives.
Storage options include two internal M.2 slots for SSDs and twenty four front-accessible hot-swap bays for U.2 NVMe SSDs. We generally recommend putting the OS on one of the M.2 slots and then using the easy-access bays in the front for storage as needed.
External connectivity consists of four USB ports (2 each in front and back) and a port for remote management. While there is no built-in networking, there are two OCP 3.0 slots for dedicated NICs.
