Ultra-Dense Peak Performance
The KL2288-E4 is a high-density AI compute tray designed for next-generation LLM training, inference, and reinforcement learning workloads. Built on the NVIDIA HGX™ Rubin NVL8 reference architecture, it integrates 8x NVIDIA Rubin SXM GPUs with NVLink and NVSwitch for high-bandwidth GPU-to-GPU communication.
Powered by dual AMD EPYC™ 9006 processors, the KL2288-E4 combines high CPU performance, PCIe 6.0 connectivity, and DDR5-8000 memory bandwidth in a compact 2U fully liquid-cooled form factor. It is optimized for AI factories, hyperscale AI farms, Neocloud providers, NCPs, and high-density AI data centers.
