About the HPE Cray XD685 GPU Compute Node

The HPE Cray XD685 GPU Compute Node is a high-density rack-mounted compute node built on liquid cooling technology compatible with HPE Cray EX and XD chassis infrastructure. This AMD EPYC processor-based system supports up to 8 GPU accelerators per node, enabling organizations to consolidate massive parallel workloads into a compact footprint. The node features high-bandwidth GPU fabric for seamless GPU-to-GPU communication within the unit, paired with high-capacity DDR5 system memory designed to handle large AI and HPC workload footprints. Local NVMe SSD storage provides fast scratch and checkpoint capabilities, while high-speed host fabric interconnect options—including InfiniBand HDR/NDR and Ethernet—integrate the node seamlessly into production clusters. Part number R9G75A represents HPE's commitment to delivering enterprise-grade GPU acceleration infrastructure for the most demanding computational challenges.

AI infrastructure teams, HPC simulation engineers, and data analytics organizations procure the XD685 to accelerate training workloads, large-scale inference pipelines, and complex scientific simulations. The node's support for AMD Instinct GPU accelerators and robust memory capacity make it ideal for enterprises scaling deep learning platforms, weather forecasting systems, and multi-petabyte analytics environments. HPE's integration with Performance Cluster Manager and iLO management infrastructure simplifies deployment and operational oversight across heterogeneous cluster environments. Linux operating system support—including RHEL, SLES, and HPE-optimized HPC OS images—ensures compatibility with established enterprise workflows and container-native architectures.

The HPE Cray XD685 (R9G75A) is available worldwide, including across UAE, GCC, EMEA, and APAC regions, making it accessible to distributed enterprise and research organizations. Omnixon Global stocks this system and can support your infrastructure expansion needs.

Frequently Asked Questions about HPE Cray XD685 GPU Compute Node

What server platforms accept the HPE Cray XD685 GPU Compute Node?

Reference servers include Dell PowerEdge XE9680 / XE9712, HPE Cray XD670, Lenovo ThinkSystem SR685a / SR675 V3, Supermicro AS-A21GE / SYS-821GE, Gigabyte G593 / G894, ASUS ESC. Share your target platform in the RFQ and we will confirm chassis-to-GPU compatibility and recommended NIC pairing.

How long is the lead time on AI GPUs?

Highly model-dependent. L40S / RTX-class: typically 3-6 weeks. H100/H200/B200 in SXM form factor: 12-16 weeks for whole-platform allocations. We quote genuine-channel ETAs only — no grey-market promises.

Do you supply matched networking (Quantum InfiniBand / Spectrum-X)?

Yes — Omnixon stocks the full NVIDIA networking lineup (Quantum-2 / Quantum-X InfiniBand, Spectrum-X Ethernet, ConnectX NICs, BlueField DPUs) so we can quote a complete training-cluster BOM, not just the GPUs.

Can you help with NVIDIA AI Enterprise licensing?

Yes. We hold genuine-channels for NVIDIA AI Enterprise software subscriptions. Add it to your RFQ and we quote node-aligned licensing along with the hardware.
