Cisco Nexus Series

IT teams need stable control over server-to-server traffic as racks, virtualisation and storage grow, and Cisco Nexus Series supports that role with leaf and spine switching for low-latency data-centre fabrics.

It fits shared data-centre environments where predictable east-west bandwidth, clear change control and workload separation matter, keeping application, storage and management traffic responsive while supporting fibre or copper access and higher-capacity fabric links as demand increases.

Cisco Nexus Series Quick Specs & Key Features

Low-latency leaf switching: Nexus 9300 leaf options connect 1/10/25G fibre or 10GBASE-T server racks with high-speed uplinks, giving data-centre teams predictable east-west traffic for storage and virtualisation without slowing rack-to-rack flows.
High-capacity fabric uplinks: 40/100G or 100/400G uplinks provide the bandwidth needed to join leaves, spines and pods, so growing workloads move between racks with reduced contention and easier scaling.
Fabric integration options: Support for NX-OS or ACI fabric operations lets teams align switching with existing change control and segmentation models, which simplifies deployment and improves auditability.

Copper access flexibility: The 93108TC supports 10GBASE-T server access for racks that still use copper adapters, allowing teams to modernise switching without replacing every host NIC and lowering migration overhead.
Compact 100G spine role: The 9336C is a 1RU 100G switch for spine or pod interconnect use, giving dense fabrics a straightforward way to carry server-to-server traffic with fewer devices and lower operational overhead.
Next-generation 400G fabric capacity: The 93600CD-GX is designed for 100G and 400G data-centre fabrics, providing bandwidth for virtualised, storage and AI-related traffic so large east-west jobs complete with better workload fit.

Cisco Nexus Series Deployment Scenarios and Industries

Data Centres

Data centre teams need leaf and spine switching that keeps server, storage and virtualisation traffic moving with low latency and clear fabric control. Cisco Nexus Series supports fibre and copper access, 100G interconnects and higher-capacity 100/400G fabrics for predictable east-west performance.

Media & Entertainment

Media teams need to move large files, live production feeds and collaboration traffic without delay between compute and storage. Cisco Nexus Series supports high-throughput data-centre fabrics for render, transcoding and content workflows where bandwidth and low latency matter.

Finance

Finance teams need low-latency connectivity for trading, risk, payments and analytics, with strict segmentation and auditability. Cisco Nexus Series supports fabric-based data-centre switching that helps keep regulated workloads separated while maintaining predictable performance.

Software Development

Software teams need fast, flexible fabrics for private cloud, CI/CD and test environments that change as projects scale. Cisco Nexus Series supports rack and pod interconnects that help keep labs, virtual clusters and developer services supplied with consistent capacity.

Telecoms

Telecoms teams need high-capacity switching for service platforms, edge clouds and virtual network functions that must stay resilient as traffic grows. Cisco Nexus Series supports data-centre fabrics that help keep subscriber and operational traffic separated and available.

Cisco Nexus Series Management and Licensing Options

Operate Cisco Nexus Fabrics from One Platform

Cisco Nexus Dashboard centralises management, automation and operational visibility across Cisco Nexus data centre fabrics. It helps infrastructure teams monitor performance, maintain policy consistency and coordinate operations across complex switching environments through one platform.

Analyse Traffic Across Switched Environments

Cisco Secure Network Analytics uses network telemetry to provide visibility into traffic moving across access, core and data centre switching environments. It helps teams understand network behaviour, identify unexpected communication patterns and investigate activity that could indicate an operational or security issue.

Designing & Supporting Cisco Nexus Series 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.

Architecture & Platform Selection: We assess your users, applications, traffic patterns, existing infrastructure, and growth plans before making any recommendations. You get the right combination of Catalyst access and core platforms or Cisco Nexus data centre switches for your environment, not an over-specified solution that costs more than necessary.
Deployment & Network Migration: Our engineers handle configuration, staging, installation, and migration across access, core, and data centre networks. VLANs, routing, uplinks, resilience, and change windows are carefully planned to minimise disruption and keep users and critical services connected.
Resilience & Performance Planning: We design Cisco switching environments around availability, capacity, and predictable application performance. Resilient uplinks, redundant core architectures, and appropriate port and power capacity help reduce single points of failure and provide a clear path for growth.

Management, Visibility & Optimisation: We help organisations use Cisco Catalyst Center and Cisco Nexus Dashboard to standardise configurations, improve visibility, and reduce repetitive administration. Existing networks can also be assessed for bottlenecks, configuration inconsistencies, and opportunities to improve performance.
Support & Lifecycle Planning: We provide ongoing technical support, upgrade guidance, capacity reviews, and lifecycle planning across Cisco switching estates. As platforms approach end of support, we help plan staged refreshes that avoid rushed replacements, unnecessary risk, and unplanned expenditure.
