NVIDIA Quantum-X800 InfiniBand switches deliver 800 gigabits per second (Gb/s)
throughput, with ultra-low latency and advanced NVIDIA In-Network Computing,
which is essential for handling trillion-parameter-scale generative AI.
These switches incorporate advanced features, including remote direct-memory
access (RDMA), the fourth-generation NVIDIA® Scalable Hierarchical Aggregation and
Reduction Protocol (SHARP)™, adaptive routing, telemetry-based congestion control,
self-healing, and Quantum-X Photonics co-packaged optics (CPO) technologies. Such
enhancements elevate overall application performance within high-performance
computing (HPC) and AI data centers.

Such enhancements elevate overall application performance within high-performance computing (HPC) and AI data centers.
Highest Scale for AI: NVIDIA Quantum-X800 switches enable 2X faster speeds and 5X higher scalability for AI compute fabrics. A two-tier Quantum-X800 fat-tree topology can support over 10,000 800Gb/s host connections. Next-Generation In-Network Computing: Quantum-X800 switches support SHARP for efficient offloading of compute operations to the network, boosting performance by up to 9X. The fourth generation of SHARP adds support for FP8 precision and new collective operations, such as ReduceScatter and ScatterGather. Higher Effective Bandwidth and Performance Isolation: Quantum-X800 switches support enhanced adaptive routing and telemetry-based congestion control. This enables nearly perfect effective bandwidth, as well as performance isolation for multi-tenant and multi-job environments. Enhanced Power Efficiency and Resiliency: NVIDIA’s new Quantum-X Photonics CPO switch reduces total power consumption, latency, and total cost of ownership (TCO) while enhancing resiliency and serviceability. This is achieved by eliminating the need for pluggable transceivers and minimizing the distance and number of connections between optics and electronics. Enhanced Software Operations: Quantum-X800 switches include NVIDIA Networking OS Software (NVOS) for comprehensive chassis management and system configuration. NVOS supports various interfaces, including a command-line interface (CLI), REST APIs, Simple Network Management Protocol (SNMP), and gRPC Network Management Interface (gNMI) telemetry.
