AI Switch Unleashing 102.4T of Ultimate Computing Power

AIS800-128O

The AIS800-128O is a 128-port 800G AI switch powered by Broadcom Tomahawk® 6. Delivering 102.4 Tbps capacity and sub-microsecond latency, it eliminates bottlenecks in hyperscale AI/ML clusters with high-radix performance and dynamic Flexport™ configurability.

Unprecedented Scale for Generative AI Workloads

The AIS800-128O is engineered to eliminate bandwidth bottlenecks in next-generation hyperscale AI and ML clusters,. Incorporating the groundbreaking Broadcom Tomahawk® 6 (BCM78910) silicon, it delivers an industry-leading 102.4 Tbps switching capacity with 1024 x 100G PAM4 SerDes technology.

Designed for sub-microsecond latency and high-radix scalability, the AIS800-128O enables the largest flat 2-tier networking topologies, significantly reducing Job Completion Time (JCT) for complex generative AI workloads.

Unmatched Performance

Features the world’s first single-chip 102.4 Tbps silicon (Broadcom Tomahawk 6) with 1024 x 100G PAM4 SerDes, designed for next-gen hyperscale infrastructure.

High-Density Connectivity

Offers 128 x 800G (OSFP800) ports. Supports up to 512 logical ports (High Radix) on a single chip to maximize network scale.

AI Workload Optimization

Reduces Job Completion Time (JCT) using Cognitive Routing, Dynamic Load Balancing (DLB), and Global Load Balancing (GLB) with sub-microsecond latency.

Robust System Design

4RU form factor with 2+2 redundant 3200W PSUs and 7+1 hot-swappable fans. Includes SyncE and PTPv2 support for precise timing synchronization.
