This dual-socket design enables exceptional compute performance, making it suitable for AI training, HPC simulation, and data-intensive modeling. Its architecture maximizes parallel processing capabilities, allowing enterprises to scale workloads seamlessly across CPUs and GPUs.
GPU and Acceleration Support
A key strength of the XD685 lies in its GPU flexibility and density. The system supports up to eight high-performance accelerators, including NVIDIA H200/B200 and AMD Instinct MI355X GPUs. This configuration provides the compute intensity required for deep learning training, large language model (LLM) processing, AI inference, and scientific computation.
The scalability of HPE XD685 SSD ensures optimal throughput for both AI development and HPC environments, supporting workloads that rely on massive data parallelism.
Memory and Storage
With support for up to 6 TB of DDR5 memory, the XD685 provides the high-speed bandwidth and responsiveness needed for memory-intensive operations. This large memory footprint allows for faster dataset access and reduced latency in training complex AI models or executing HPC simulations.
Its storage options can be configured for high-capacity local data caching or fast-access NVMe storage, depending on workload requirements.
Cooling and Efficiency
The XD685 is available in both air-cooled and direct liquid-cooled configurations, giving organizations the flexibility to match their thermal and power efficiency goals.
-
The air-cooled model offers simplified installation and maintenance for traditional data centers.
-
