Cisco Nexus 9364D-GX2A Overview

As east-west traffic rises across larger compute, storage and accelerator clusters, infrastructure teams need denser 400G fabrics that keep growth orderly without adding unnecessary switching layers.

High-Density Fabric Switching for Modern Production Environments

The Cisco Nexus 9364D-GX2A is a fixed-form data-centre switch for 400G spine and AI fabric roles in large leaf-spine environments. It is built for dense aggregation and spine deployments where more fabric capacity is needed.

Designed to Carry More Work Through the Same Fabric

With up to 66 network ports at 400 Gbps, the platform is suited to high-port-density fabrics that must connect more systems through fewer switches. RDMA support helps it fit low-latency, high-throughput cluster traffic.

Operational Fit That Supports Scale

This gives operators a practical way to expand shared network capacity while reducing cabling, rack usage and switching complexity. It also supports larger pods and spine layers without forcing workloads into separate networking domains.

If you are planning a Cisco Nexus 9364D-GX2A deployment, our team can help you assess the fit for your fabric design and operational requirements.

Cisco Nexus 9364D-GX2A Key Features​

The Cisco Nexus 9364D-GX2A is a data center switching platform for high-density network environments, providing a foundation for scalable fabric designs and operational consistency across modern enterprise infrastructure.

High-Density Fabric Scaling

Large-Port Aggregation
The platform supports dense network connectivity with up to 66 ports, helping consolidate many endpoints within a single switching layer.

400 Gbps Uplink Capacity
Maximum port speeds of 400 Gbps support high-bandwidth fabric design for demanding east-west and aggregation traffic.

Data Center Interconnect Role
Its switching architecture is suited to environments that require structured connectivity between servers, storage, and higher-level network tiers.

Modern Network Alignment
The platform is designed for current data center architectures that need scalable throughput without changing the underlying switching model.

Operational Consistency and Control

RDMA Readiness
RDMA support helps the platform align with low-latency network designs that rely on efficient direct data movement.

Fabric Stability
A structured switching model supports predictable network behavior in environments where consistent forwarding is important.

Enterprise Deployment Flexibility
The platform can be applied across enterprise data center environments that need reliable infrastructure networking at scale.

Cisco Nexus 9364D-GX2A Deployment Scenarios

The Cisco Nexus 9364D-GX2A is a high-density 400G switching platform for large scale-out fabrics, where east-west traffic, cluster growth, and operational simplicity all matter. It fits environments that need fewer switches, more fan-out, and predictable capacity at scale.

Large Data Centre Spine Layers

In larger data centre pods, spine layers must carry heavy east-west traffic between compute, storage, and accelerator clusters. The Cisco Nexus 9364D-GX2A suits this role when teams want to reduce switch count and cabling pressure without limiting growth.

Telecom Cloud and Network-Function Fabrics

Telecom platforms running virtualised network functions need dense aggregation with enough fan-out for many high-speed nodes. This switch fits when the fabric must absorb rapid expansion while keeping the core network layout simpler to operate.

AI and Distributed Development Clusters

Software development teams building AI and distributed compute clusters need a shared fabric that can move data quickly between many active systems. The 9364D-GX2A supports this when teams want to avoid splitting projects across smaller switching domains.

Finance Analytics and Data-Processing Clusters

Financial analytics environments often run compute and storage nodes in parallel, creating constant east-west demand. This platform is a practical choice when predictable bandwidth, dense connectivity, and easier fabric consolidation are more important than adding more switches.

Media Rendering and Shared Storage Fabrics

In media and entertainment, render farms and shared storage fabrics must pass large files between many production nodes at the same time. The Cisco Nexus 9364D-GX2A helps maintain a simpler network layer as these workloads scale.

Planning a Cisco Nexus 9364D-GX2A Deployment?

Our team can help design and deploy Cisco Nexus 9364D-GX2A switching for data centres, telecom fabrics, AI clusters, finance platforms, and media production environments with the right capacity and operational fit.
