NVIDIA Switch-IB 2 SB7800 Series 100Gb/s InfiniBand Switch

1. Product Overview

The NVIDIA Switch-IB 2 SB7800 Series is a high-performance, 100Gb/s InfiniBand switch designed for modern data centers requiring extreme bandwidth, low latency, and scalable interconnect solutions. Ideal for HPC, AI, and large-scale cloud environments, this network switch delivers 36 non-blocking ports in a compact 1U form factor, offering an aggregate throughput of 7.2 Tb/s. It supports advanced in-network computing and is available in both internally and externally managed configurations.

2. Key Characteristics

• 36 ports of 100Gb/s InfiniBand per port
• 7.2 Tb/s aggregate bidirectional throughput
• Ultra-low port latency for enhanced application performance
• Redundant, hot-swappable power supplies and fans
• Energy-efficient design with ATIS weighted power as low as 122W
• Support for NVIDIA SHARP™ in-network acceleration technology

3. Core Technology

The network card and switch leverage NVIDIA’s Scalable Hierarchical Aggregation and Reduction Protocol (SHARP), which offloads collective operations from CPUs to the switch, significantly reducing MPI operation times and network traffic. The switch runs on MLNX-OS for comprehensive management and integrates seamlessly with NVIDIA UFM® platforms for AI-driven network analytics and telemetry.

4. Working Principle

The SB7800 operates as a top-of-rack or spine network switch, utilizing a non-blocking architecture to ensure full bandwidth across all ports. It processes data through its integrated Intel Celeron dual-core CPU and offloads collective communication tasks via SHARP, reducing CPU overhead and minimizing latency for high-performance workloads.

5. Applications

• High-Performance Computing (HPC) clusters
• Artificial Intelligence and Machine Learning training networks
• Large-scale data analytics and cloud infrastructure
• Research and enterprise data centers
