With a maximum processor TDP of 300W under air cooling, the Supermicro GPU 221GL-NHIR provides a high-speed interconnect between both GH200 Superchips via NVIDIA BlueField-3 or ConnectX-7 for large-scale AI workloads. The system supports up to 12TB of coherent memory, including 960GB of LPDDR5X and 288GB of HBM3e, enabling seamless handling of memory-intensive LLM applications. For storage, this platform accommodates 8x hot-swap E1.S NVMe drive bays, with 3x fixed front drives, and includes 2x M.2 NVMe slots for OS boot drives. Expansion capabilities include 4x PCIe 5.0 x16 slots: 3x with x16 signals and 1x with an x4 signal, which are accessible through the rear of the chassis.
System management is provided through a dedicated RJ45 1GbE IPMI LAN port, with monitoring options available via Supermicro SuperDoctor 5 (SD5). This tool offers both command-line and web-based interfaces for Windows and Linux environments, with real-time monitoring of CPU temperature, power consumption, system voltages, and fan speed. Users can receive automated alerts via email or SNMP in case of an error. This server is powered by 4x 2000W redundant (2+2) Titanium-level hot-plug PSUs.
*This product can only be sold with a minimum of 2x GH200s, 1x HDD/M.2 storage device, and 1x NIC per system.
