Requiring a complete liquid-cooled rack integration, the Supermicro AI Training SuperServer 421GE-NBRT-LCC features 2x 4th or 5th generation Intel Xeon Scalable processors. With a maximum TDP of up to 385W, each CPU can deliver up to 64 physical cores, and 128 virtual threads. It supports up to 8x SXM form factor HGX B200 180GB Blackwell GPUs. The GPUs feature a PCIe 5.0 x16 CPU-to-GPU Interconnect utilizing NVIDIA’s NVLink with NVSwitch for maximum throughput. The 64-GPU scalable SRS-48UDLC-4U8N-L1 unit can accommodate up to 8x of these systems.
Built for high-performance computing, conversational AI, healthcare applications, and more, the Supermicro SuperServer 421GE-NBRT-LCC can be purchased as a complete liquid-cooled system with a 250kW coolant distribution unit (CDU). This platform offers 32x DDR5 DIMM slots capable of supporting up to 8TB of RDIMM memory running at speeds of up to 4400MT/s with 2DPC. Meanwhile, 1DPC supports 4TB of memory running at up to 5600MT/s. The front of the chassis holds 8x front hot-swap 2.5" NVMe drive bays, plus 2x M.2 NVMe slots on the motherboard. Default expansion options include 2x PCIe 5.0 x16 FHHL slots and 8x PCIe 5.0 x16 LP or option A with 4x PCIe 5.0 x16 FHHL slots and 8x PCIe 4.0 x16 LP slots. This system is capable of hosting 2x dual-port NVIDIA BlueField-3 DPUs and 8x single-port NVIDIA ConnectX-7 NICs or NVIDIA BlueField-3 SuperNICs. Four 6600W redundant (2+2) Titanium Level PSUs are located at the rear of the chassis to supply power to this system.
The 421GE-NBRT-LCC can be managed by administrators using a variety of management software programs, such as SuperCloud Composer, SuperServer Automation Assistant (SAA), Supermicro ThinAgent Service (TAS), and Super Diagnostics Offline (SDO). With SAA, it is possible to remotely or locally configure and upgrade a single node or the whole network.
