The Arista 7504R provides a compact routed platform for data centre spine and aggregation designs that need predictable performance under heavy load. Its modular chassis with redundant supervisors and hot-swappable PSUs supports resilient operations while keeping bursty traffic flowing smoothly.
As routed workloads, replication flows and high-density application traffic converge on smaller core layers, infrastructure teams need compact platforms that keep forwarding predictable without adding operational sprawl.
The Arista 7504R is a 4-slot modular switch router for dense core, DCI and aggregation deployments where routed chassis resilience and scalable throughput matter. It suits enterprise and service provider environments that need a smaller footprint than larger chassis without giving up core-class behaviour.
With 400G port support, QSFP28 and QSFP-DD interfaces, and 230400 Gbps of switching capacity, the platform is set up for bursty traffic and large routing domains. Its deep-buffer, high-scale L2/L3 design helps keep traffic moving cleanly across core and aggregation paths.
Hot-swappable PSUs support maintenance without unnecessary interruption, which matters when the platform sits on critical data paths. The result is a routed layer that is easier to standardise, simpler to scale and more practical to run under sustained load.
For a closer look at the Arista 7504R in your environment, our team can help assess fit, deployment role and integration options.
The Arista 7504R is a modular networking platform for data center and core environments, designed to support high-capacity forwarding, resilient operation, and scalable network growth across enterprise deployments.
High-Capacity Switching Fabric
The platform provides an aggregate switching capacity of 230400 Gbps to support large-scale traffic handling in demanding network environments.
400G Interface Readiness
It supports maximum port speeds of 400G, enabling high-throughput connectivity for bandwidth-intensive data center architectures.
Modular Network Growth
The system architecture is suited to expanding network roles without changing the underlying platform, supporting growth in core and aggregation deployments.
Data Center and Core Alignment
Its design aligns with environments that require centralized forwarding, scalable connectivity, and predictable operation at the network core.
Hot-Swappable Power Supply Design
Hot-swappable PSUs support serviceable power maintenance without taking the platform out of operation.
Redundant Power Architecture
Power redundancy helps preserve platform availability by reducing exposure to a single power-supply failure.
Operational Continuity Focus
The platform is built to sustain network function in environments where infrastructure uptime is an operational requirement.
If you are planning a high-capacity core or data center network, our team can help align the Arista 7504R with your performance, scaling, and resilience requirements.

The Arista 7504R is a compact routed chassis for environments that need high-scale forwarding at aggregation points rather than a full core build-out. It fits bursty traffic patterns, dense route tables and operational teams that want predictable behaviour under load.
In smaller data centres, the 7504R is often placed at the routed core or storage aggregation layer where replication, backup and workload mobility create uneven traffic. Its buffering and route depth help keep delivery steady when demand spikes.
Media teams can deploy the 7504R between production storage, render systems, archive platforms and remote collaboration links. It helps reduce congestion when large files move across rooms or sites, supporting time-sensitive creative work without adding operational strain.
Financial firms use the 7504R for routed aggregation around market-data feeds, analytics clusters and regulated zones. It suits sites that need deterministic forwarding and scale for busy data paths, while keeping the platform compact and manageable.
In energy and utilities, the 7504R can sit between OT data platforms, control-room services, enterprise systems and analytics layers. It supports segmented routing where uptime and clear separation matter during grid-modernisation and systems integration projects.
Telecom operators can place the 7504R at regional aggregation, packet-core support or DCI handoff points. It handles bursty service traffic and larger routing domains without forcing smaller sites to adopt an oversized fixed leaf design.
Our team can help design and deploy Arista 7504R routing for data centres, media environments, financial networks, utility control centres and telecom aggregation sites, with deployment guidance shaped around resilience, scale and day-to-day operations.
