Arista Data Centre Switching

Arista

As private clouds and shared storage grow, Arista Data Centre Switching helps IT teams keep east-west traffic local, control congestion and maintain predictable performance across server, storage and interconnect layers.

It suits workload pods, rack access and routed aggregation where growth, segmentation and traffic bursts strain the fabric. Dense 25GbE and 100GbE options, plus higher-capacity 400GbE switching, support standardised rollouts, stronger buffering and cleaner paths as environments scale.

Arista Data Centre Switching Quick Specs & Key Features

  • High-density 100GbE fabric: 1RU models with 32x 100GbE QSFP ports or 64x 400GbE ports give storage, virtualisation and cluster traffic a local path, keeping east-west flows off the shared core and reducing latency.
  • Balanced uplink architecture: 25GbE leaf models with 48x 25GbE server ports and 8x or 12x 100GbE uplinks give rack access more upstream capacity, helping dense workloads avoid oversubscription and lowering rack-level congestion.
  • Low-latency packet handling: Cut-through switching with shared or dynamic buffering absorbs bursts in storage, backup and analytics traffic, which reduces packet loss and retransmissions under load.

  • Flexible breakout options: Support for 100GbE breakout to 10/25/50GbE lets teams mix server speeds in one fabric, simplifying migration from lower-speed links and reducing deployment complexity.
  • Routing and policy scale: Routing-optimised and high-scale models add larger route and policy capacity for VRFs, EVPN and inter-pod aggregation, supporting segmented multi-tenant fabrics with better workload fit.
  • Shared-storage resilience: Deep buffering and burst absorption protect render, backup and database transfers when many endpoints converge on the same storage target, improving availability during peak load.

Arista Data Centre Switching Deployment Scenarios and Industries

Data Centres

Data centre teams need repeatable fabric designs for virtualisation, storage and database pods, with heavy east-west traffic kept close to the servers. Arista Data Centre Switching supports this with dense 25GbE and 100GbE leaf options, burst-tolerant switching and higher-speed aggregation for routed workloads.

Media & Entertainment

Media teams need local high-speed paths for render nodes, ingest systems, edit suites and shared storage, where large files move continuously and delays affect production. Arista Data Centre Switching supports these environments with low-latency fabric designs and higher uplink capacity for file-heavy workflows.

Finance

Finance teams need predictable network paths for analytics, market data, risk engines and database acceleration, with enough isolation to separate sensitive application domains. Arista Data Centre Switching supports contained, policy-aware fabrics that combine 25GbE or 100GbE rack access with routed aggregation for time-sensitive workloads.

Software Development

Software teams need private-cloud and CI/CD fabrics where build runners, container hosts, artifact stores and test databases move large datasets repeatedly. Arista Data Centre Switching supports scalable lab and platform environments with dense server access, stronger uplinks and routed boundaries for multi-tenant use.

Telecoms

Telecoms teams need flexible fabrics for NFV, packet-core and MEC labs, where appliances, traffic generators and service chains are staged together and often mix 100GbE with lower-speed links. Arista Data Centre Switching supports this with compact leaf, routed aggregation and high-scale interconnect options.

Designing & Supporting Arista Data Centre Switching Solutions

Backed by decades of expertise in the IT sector, our specialists support every stage of your deployment — from initial selection through to long-term lifecycle management.

  • Tailored Arista Access Switching: Access layer switching must support far more than basic connectivity — user density, PoE, wireless growth, IoT devices, VLAN segmentation, and application traffic all place different demands on the network edge. We design Arista access-switching environments aligned with your real operational requirements, avoiding oversubscribed uplinks, inconsistent configurations, and performance bottlenecks as you scale.
  • Arista Core Switching & Data Centre Architecture: Growing environments can quickly expose core network limitations as east-west traffic, virtualisation, storage workloads, and application demands increase. We design resilient Arista core switching architectures built around throughput, redundancy, low-latency traffic handling, and long-term scalability — keeping high-performance enterprise and data centre environments stable under sustained load.
  • Deployment, Integration & Network Configuration: Switching deployment involves far more than racking hardware. We handle switch configuration, stack deployment, VLAN design, routing integration, migration planning, and interoperability validation across wireless, firewall, storage, and virtualisation environments — reducing deployment risk and minimising disruption during upgrades, expansions, and infrastructure refresh projects.

  • Network Visibility, Performance & Operational Efficiency: Poor visibility, inconsistent configuration, and inefficient traffic handling erode network reliability over time. We help improve segmentation, management visibility, and traffic optimisation across your Arista switching environment — delivering consistent, reliable performance during peak demand and day-to-day operations alike.
  • Scalability, Resilience & Lifecycle Planning: Network requirements rarely stay static. As your environment grows, we help plan for higher uplink speeds, additional switching capacity, improved redundancy, firmware strategy, and long-term lifecycle management — keeping your Arista infrastructure high-performing and future-ready.
