About the HPE Cray XD685 GPU-Optimized Server
The HPE Cray XD685 is a 5U rack-mounted, direct liquid-cooled GPU-optimized server engineered for next-generation high-performance computing and AI workloads. Built on the HPE Cray XD Series platform, this system combines dual AMD EPYC 9004 Series (Genoa) processors with support for up to 8 double-width GPU accelerators in SXM / OAM-compatible form factors, delivering exceptional compute density and thermal efficiency in enterprise datacenter environments. The direct liquid cooling technology ensures sustained performance under demanding parallel processing loads while maintaining operational reliability in large-scale deployments.
This server is purpose-built for AI infrastructure teams, HPC clusters, and enterprise GPU computing initiatives that demand maximum GPU throughput and low-latency interconnection. The HPE Cray XD685 features DDR5 ECC Registered memory, PCIe Gen 5 connectivity, and readiness for HPE Slingshot 200Gb/s high-speed interconnects to support tightly coupled multi-node supercomputing topologies. Equipped with NVMe SSD boot and data storage support, redundant high-efficiency AC power supplies, and HPE iLO remote management capabilities, the system simplifies deployment and lifecycle management across large clusters. HP's robust operating system support includes Red Hat Enterprise Linux, SUSE Linux Enterprise, and Ubuntu HPC-optimized distributions, enabling flexible software stack integration. Whether architecting an AI supercomputing platform or scaling an enterprise GPU cluster, the HPE Cray XD685 (part number P77410-B21) from HP delivers the performance, reliability, and management capabilities required for mission-critical workloads.

Frequently Asked Questions about HPE Cray XD685 GPU-Optimized Server
What server platforms accept the HPE Cray XD685 GPU-Optimized Server?
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.
