Highlights

First-Class Performance

Support up to 128 x 800 GbE ports with full line-rate L2/L3 forwarding, lossless Ethernet, and RoCEv2, eliminating network bottlenecks that impede GPU-to-GPU communication in distributed training and inference.

Built for AI

The Aria Switch 800G product lines support dynamic load balancing and adaptive routing, which eliminate microsecond-scale congestion events that degrade MFU performance across training and inference deployments.

Trusted and Proven

Aria switches are ONIE-loaded and powered by Aria Enterprise SONiC, offering hyperscaler-class scale and rock-solid reliability, accelerating time to production while meeting the most stringent mission-critical requirements.

Resilient by Design

1+1 redundant, hot-swappable power supplies and 3+1 redundant, hot-swappable fans ensure hardware faults never become training interruptions. Front-to-rear airflow aligns with standard data center cooling architectures.

AMD Certified

Aria Switch 800G is certified by AMD for Pollara 400 AI NIC.
