Features & Fabric Capabilities - High Radix: 144 XDR ports in a single 4U chassis enables high-density spines for two-level fat-tree fabrics.
- Scalable Topologies: Ideal as a spine in Fat-Tree, Dragonfly+, multi-dimensional Torus and custom AI factory topologies.
- SHARP & In-Network Acceleration: Supports SHARP collective offloads and hardware-accelerated reductions for distributed training.
- Adaptive Routing & Congestion Control: Hardware-assisted adaptive routing and advanced congestion mitigation for stable application performance.
- Interoperability: Designed to interoperate with ConnectX-8 adapters and BlueField DPUs and integrate with NVIDIA UFM and telemetry stacks.
- Router Option: Optional router capability to extend and bridge InfiniBand fabrics across sites or routing domains.
- Secure Firmware & Management: Secure boot, authenticated firmware updates, and role-based access control for multi-tenant deployments.
Environmental, Mechanical & FRU Summary - Chassis: 4U, standard depth rack (177.8 × 438 × 850 mm).
- FRUs: 8 × hot-swappable PSUs, 10 × hot-swappable fans, replaceable connector cages (OSFP), and console/management modules.
- Thermal: Air-cooled with front/rear airflow options depending on SKU and rack configuration.
- Monitoring: Integrated telemetry, thermal thresholds, and event logging for predictive maintenance and automated operations.
