AI and machine learning training demands accelerator density and liquid cooling efficiency, and the HPE Cray XD685 delivers both in a single 5U platform. Purpose-built for enterprises scaling large language model fine-tuning and multi-modal inference, this HP system combines up to 8 double-width GPU accelerators with Direct Liquid Cooling (DLC) technology to maximize performance per rack footprint. The XD685 runs on AMD EPYC processors with PCIe Gen 5 connectivity, ensuring low-latency data movement between compute and accelerators while maintaining thermal headroom in dense deployments.

Infrastructure architects and AI engineering teams will appreciate the high-density, air and liquid hybrid-capable chassis design paired with HPE Slingshot high-speed interconnect fabric for multi-node clusters. Management is centralized through HPE iLO (Integrated Lights-Out), and the platform supports Linux distributions including RHEL, SLES, and HPE-validated variants. NVMe storage interfaces and redundant, high-efficiency power supplies round out a platform engineered for 24/7 HPC simulation and production inference workloads. Part number R9K05A identifies this configuration for procurement and deployment planning.

Typical Workloads and Deployment Scenarios

• AI/ML training pipelines requiring sustained GPU utilization and multi-accelerator scaling
