Arista Networks, a leader in cloud and AI networking, has unveiled groundbreaking advancements aimed at optimizing AI cluster performance and efficiency. The newly introduced Cluster Load Balancing (CLB) in Arista EOS enhances AI workload performance by ensuring consistent, low-latency network flows. Additionally, Arista CloudVision Universal Network Observability (CV UNO) now provides AI job-centric observability, allowing for enhanced troubleshooting and faster issue resolution to ensure job completion reliability at scale.

Enhancing AI Infrastructure with Smart Networking

The Arista EOS Smart AI Suite strengthens AI clusters with Cluster Load Balancing, an advanced Ethernet-based AI load-balancing solution. Unlike conventional methods that struggle with AI workloads’ large-bandwidth flows, CLB optimizes traffic using RDMA-aware flow placement. This innovation ensures uniform high performance, minimizes congestion, and maintains low tail latency, leading to better AI model training and inference outcomes.

” As Oracle expands its AI infrastructure on Arista switches, smart load balancing is key to avoiding network bottlenecks and boosting ML performance,” said Jag Brar, Vice President and Distinguished Engineer at Oracle Cloud Infrastructure. “Arista’s Cluster Load Balancing feature efficiently tackles these challenges.

Achieving Holistic AI Observability

Arista’s AI-driven CV UNO platform, powered by Arista AVA™, delivers comprehensive network observability by integrating AI job data with network and system insights within the Arista Network Data Lake (NetDL™). Unlike traditional SNMP polling, EOS NetDL Streamer provides real-time, high-frequency telemetry, capturing critical network performance insights essential for large-scale AI training and inference infrastructure. Key benefits include:

  • AI Job Monitoring: Offers real-time insights into job health metrics, congestion indicators, and buffer utilization.
  • Deep-Dive Analytics: Identifies performance bottlenecks by analyzing network devices, server NICs, and associated flows.
  • Flow Visualization: Uses CV topology mapping to provide microsecond-level insights into AI job flows.
  • Proactive Issue Resolution: Detects anomalies early and correlates network and compute performance for seamless AI operations.
