Arista 7800R4 Series Modular Data Center Switch

The Arista 7800R4 Series is a modular chassis switch engineered for AI and machine learning data center deployments requiring ultra-high-density, scalable interconnect. The platform supports up to 800G per port connectivity, enabling massive east-west fabric throughput for GPU-accelerated workloads and distributed training environments. Its modular architecture allows operators to configure line cards, fabric modules, and supervisors to match evolving cluster topologies and traffic patterns.

Designed as a spine-layer switch, the 7800R4 delivers the non-blocking throughput and low latency required for collective communication patterns inherent to large-scale AI model training. Built-in redundancy, hitless upgrades, and full-duplex 800G SerDes technology ensure carrier-grade availability for mission-critical HPC and cloud infrastructure. Arista EOS operating system provides API-driven network automation, telemetry, and programmable packet handling for seamless integration into modern data center orchestration frameworks.

Ideal for

• AI training cluster spine interconnect for multi-rack GPU arrays and distributed parameter servers
• High-performance computing (HPC) fabric for scientific simulation, molecular dynamics, and weather modeling
• Cloud service provider data center core switching with 800G uplinks and tenant isolation via VxLAN/EVPN
• Hyperscaler storage array interconnect for fault-tolerant distributed filesystems and object storage
• Real-time financial trading infrastructure requiring sub-microsecond latency and deterministic jitter
• Edge-to-core federation in large enterprise multi-campus networks with persistent state replication
