Additional InformationFour independent nodes occupy the MiTAC C2811Z5X4E1XDR-555 chassis, with each featuring 1x AMD EPYC 9555 processor with a cTDP of up to 400W. Direct liquid cooling is used to manage the thermal requirements of the high-density platform and maintain performance under sustained workloads. Memory capacity reaches up to 3TB per node across 12x DDR5 RDIMM slots, with speeds of up to 6400MT/s. For local storage, each node provides 4x hot-swappable NVMe E1.S drive bays with PCIe Gen5 x4 connectivity.
Networking and additional connectivity are supported by 2x OCP 3.0 PCIe 5.0 mezzanine slots per node. This provides flexibility for high-speed networking, storage controllers, and other compatible expansion options. System management and security are integrated through a DC-SCM 2.0 module featuring an ASPEED AST2600 BMC and AST1060 Root of Trust. Designed specifically around the ORv3 infrastructure standard, the C2811Z5X4E1XDR-555 receives power through a 48V DC busbar rather than conventional server power supplies.
