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.
