About the Lenovo ThinkSystem SR680a V4
The Lenovo ThinkSystem SR680a V4 is an 8U flagship AI training platform pairing two Intel Xeon 6700-series processors (up to 86 P-cores each, 350W) with eight integrated NVIDIA HGX B300 GPUs on a 1100W 8-GPU board. Each GPU carries 270 GB of HBM3e for 2.16 TB of accelerator memory across the node, linked by 1.8 TB/s NVLink and integrated NVSwitch for direct all-to-all GPU communication, and fed by eight ConnectX-8 800 Gb/s OSFP interfaces with GPU Direct. Developed in-house by Lenovo and designed for air-cooled data centres, it is purpose-built for the most demanding generative AI, HPC and large-scale analytics workloads.
Supporting up to 4TB of TruDDR5 memory across 32 DIMM slots at 6400 MHz, eight PCIe 5.0 NVMe front drive bays plus M.2 boot, four PCIe 5.0 x16 FHHL slots and an OCP slot, the SR680a V4 balances raw accelerator throughput with fast local storage and flexible networking. Resiliency comes from eight 80 PLUS Titanium power supplies (3200W AC N+1 or 3800W HVAC N+N), 21 hot-swap fans, XClarity Controller 3 management and a hardware Root of Trust with PFR and TPM 2.0. Servnet configures, prices and supplies the ThinkSystem SR680a V4 in the UK, with every specification here verified against the Lenovo Press product guide.
