Presentation
Arista EtherLink™ AI Networking
DescriptionThe Arista EtherLink AI networking platform introduces a modular, scalable architecture with a unified lossless dataplane across distributed, independent components. Each component, equipped with its own control and data planes, is interconnected via high-speed Ethernet links.
By embracing Ethernet, it ensures interoperability and optimizes for currently available, cost-efficient RDMA NICs.
Key technical benefits:
- Scalable AI Networking: EtherLink losslessly connects 32,000 XPUs in one cluster, or 100,000 across multiple data centers at 800 Gbps.
- Proven Reliability and Performance: The system has been field-tested by hyperscalers and is validated through large-scale simulations. Simulations indicate a 10% to 30% improvement in job completion time.
- Fast Failure Recovery: EtherLink uses hardware-accelerated link fault detection and repair for milliseconds-level recovery.
- EOS Integration: Arista's EOS® provides centralized control, telemetry, and quality of service (QoS) management, supporting configuration, monitoring, and debugging of AI/ML workloads from network to NIC.
At its core, EtherLink incorporates Broadcom's Jericho3 packet processor and Ramon3 fabric chips. These components target the requirements of AI/ML, offering advanced load balancing, congestion management, and fault resilience.
This presentation discusses the design, motivations, and technical foundations of the EtherLink solution.
