The Arista 7304 provides resilient spine and aggregation connectivity for data centre environments that need controlled modular growth. Its 4-slot chassis design with redundant supervisors supports capacity expansion while keeping changes centralised and easier to manage.
As compute, storage and application domains expand, infrastructure teams need a compact way to add capacity and maintain resilience without increasing space, power or operational overhead.
The Arista 7304 is a modular data centre switch for spine deployments, built for growing aggregation and spine environments that need chassis resilience without the footprint of a larger system. It supports QSFP28 and QSFP-DD ports and reaches up to 400G per port.
Its four-slot chassis architecture separates supervisor, fabric and line-card functions, so capacity can be added by installing line cards rather than replacing the whole switch. That makes expansion more contained and easier to plan around live operational windows.
With 150000 Gbps of switching capacity, the platform gives network teams room to grow spine bandwidth while keeping the environment centralised and manageable. It suits estates where resilience, modular growth and a smaller physical footprint matter equally.
Our team can help you assess the Arista 7304 for your spine or aggregation design and align it with current and future port requirements.
The Arista 7304 is a network platform for enterprise and service provider environments, designed to deliver high-capacity connectivity, scalable routing, and operational consistency across demanding infrastructure deployments.
400G Port Capability
The platform supports high-speed connectivity with maximum port speeds of 400G for dense uplink and backbone designs.
Large-Scale Switching Capacity
Its forwarding architecture is built for aggregate throughput, with switching capacity validated at 150,000 Gbps.
Dynamic Routing Support
The system provides dynamic routing capability to support adaptive path selection across changing network topologies.
Scalable Network Core
The platform is suited to aggregation and core roles where higher bandwidth and routing scale are required in a single chassis design.
Routing Policy Flexibility
Dynamic routing enables the network to adjust traffic paths based on current reachability and topology conditions.
Infrastructure Alignment
The platform fits environments that require predictable network behaviour across enterprise and service provider architectures.
Deployment Consistency
Its architecture supports standardized use across new and refurbished variants without changing the product role or platform model.
When you need to design high-capacity routing infrastructure or validate fit for core network growth, our team can help align the Arista 7304 to your operational requirements.

The Arista 7304 is a compact modular chassis for teams that need resilient aggregation or spine capacity in space-constrained environments. It fits compute halls, production networks and labs where line-card growth, controlled change and operational simplicity matter more than large chassis scale.
In small to medium compute halls, the 7304 works as a modular spine or aggregation chassis when server and storage connectivity keeps growing. It gives network teams chassis resilience and expansion headroom without the footprint and overhead of a larger fixed platform.
Studios can place the 7304 between edit rooms, render racks and shared storage to support shifting throughput as projects move between phases. Its modular growth helps teams add capacity without replacing the switching layer during active production.
For finance teams supporting analytics, reporting or market-data staging, the 7304 provides a contained platform where network changes must stay governed. It supports capacity increases in one chassis, avoiding a spread of smaller devices across regulated domains.
Platform engineers can use the 7304 in private-cloud, CI and performance-lab environments where clusters, Kubernetes nodes and storage shelves appear over time. It offers production-like modular networking without the scale, space or cost of an eight-slot chassis.
Telecoms labs and edge pods often need to swap interface types and port speeds between test cycles. The 7304 lets engineers keep one contained aggregation point while accommodating changing appliance mixes and service-chain validation requirements.
Our team can help design and deploy Arista 7304 switching for data centres, media networks, finance pods, software platforms and telecoms validation estates with the right growth path, resilience model and operational fit.
