5U Tower Server for AI Training

The Supermicro SYS-751GE-TNRT-NV1 is a 5U tower system designed for AI and HPC workloads. It arrives with four liquid-cooled NVIDIA A100 GPUs linked by NVLink bridges in a 2+2 configuration. Dual 4th Gen Intel Xeon 6444Y processors, each with 16 cores at 3.60 GHz, are installed in the dual LGA-4677 sockets. Ubuntu 22.04 LTS and the Supermicro Cloud Orchestrator AI software stack are pre-loaded.

PCIe 5.0 and NVLink GPU Interconnect Limits

Each GPU connects to the CPUs through a PCIe 5.0 x16 link, providing the CPU-to-GPU bandwidth ceiling for this platform. GPU-to-GPU communication is handled by the installed NVLink bridges in a 2+2 topology rather than a full mesh. The dual-port NVIDIA ConnectX-6 Dx adapter adds a 25GbE SFP28 link, while the Intel X550-AT2 supplies two 10GbE Base-T ports and the ASPEED AST2600 provides a 1GbE management port. Storage connectivity is limited to the SATA III interface with RAID 0, 1, 5, 10 support.

512 GB DDR5-4800 ECC Memory Ceiling

The board offers 16 DIMM slots populated with DDR5-4800 ECC modules, capping total system memory at 512 GB using 16×32 GB DRAM. No memory is installed from the factory, so the buyer must procure the full complement to reach the maximum. The Intel C741 chipset governs this limit; future 5th Gen Xeon support is noted but does not alter the current memory capacity or speed specification.
