QFX5241-64OD Overview

As AI clusters, cloud platforms and storage environments move more traffic across the fabric, data centre teams need higher port density and more bandwidth without adding unnecessary switching layers.

High-Density Switching for AI and Cloud Fabrics

The Juniper QFX5241-64OD is a fixed 2U data centre switch for spine, leaf and end-of-row deployments where large numbers of high-speed links must be brought into one fabric. It suits AI, GPU, cloud and large-scale storage environments that need substantial capacity in a compact platform.

Built for 800GbE Fabric Connectivity

With 64×OSFP 800GbE ports and 51.2 Tbps of system throughput, the switch provides the bandwidth needed to connect dense compute, storage and aggregation layers. Breakout support also allows teams to introduce lower-speed links where required without changing the core platform.

Operational Headroom for Growing Data Centres

Running Junos OS Evolved, the Juniper QFX5241-64OD gives infrastructure teams a consistent operating model for high-capacity fabric deployments. Its high-radix design helps reduce switch count, simplify scaling and preserve headroom as AI and cloud workloads expand.

If you are planning a new fabric or increasing capacity in an existing environment, our team can help assess where the Juniper QFX5241-64OD fits and how to configure it around your port-speed and topology requirements.

QFX5241-64OD Key Features​

Juniper QFX5241-64OD is a high-density data centre switch for AI, cloud and storage fabrics that need scalable 800GbE connectivity, substantial switching capacity and a consistent operational platform.

High-Capacity Fabric Performance

64-Port 800GbE Connectivity
The switch provides 64 OSFP ports supporting speeds up to 800GbE for dense spine, leaf and end-of-row fabric deployments.

51.2 Tbps Switching Capacity
A 51.2 Tbps system throughput supports high-volume traffic between GPU clusters, compute nodes, storage systems and upstream network layers.

Flexible Port Channelisation
Channelisation support allows OSFP ports to connect lower-speed interfaces where required, helping teams introduce mixed link speeds without changing the switching platform.

Compact 2U Design
The fixed 2U form factor delivers high port density without requiring a modular chassis, helping reduce rack consumption in capacity-constrained data centres.

Fabric Scale and Operational Control

Flexible Fabric Placement
The platform can operate in spine, leaf or end-of-row roles, allowing network teams to align the switch with different IP fabric architectures.

Junos OS Evolved Management
Junos OS Evolved provides a consistent operating and automation model for configuring, monitoring and maintaining large-scale data centre fabrics.

High-Radix Fabric Expansion
The dense port layout can connect more fabric links from a single switch, helping reduce switching layers and preserve expansion capacity as AI and cloud environments grow.

QFX5241-64OD Deployment Scenarios

The Juniper QFX5241-64OD is a 64-port 800GbE data centre switch for AI fabrics, cloud platforms and large-scale storage environments that need dense east-west capacity, predictable fabric performance and room to scale beyond 400GbE tiers.

Large AI and GPU Training Fabrics

In enterprise and colocation data centres, the QFX5241-64OD suits dense GPU clusters where model training and checkpoint traffic place sustained pressure on the network. Its high-radix design helps connect more accelerated nodes while reducing the need for additional switching layers.

Private Cloud and Platform Engineering Clusters

Software and platform teams use it where compute, storage and test environments exchange large volumes of data across shared fabrics. The switch provides 800GbE headroom for lab-to-production workflows without forcing teams to redesign the network as cluster density grows.

Risk Analytics and Financial Modelling

Finance environments running simulations, market-data processing and AI analytics need tight control over latency and oversubscription. The QFX5241-64OD provides a high-capacity fabric tier for moving larger datasets between compute and storage systems during time-sensitive processing.

Rendering and Shared Storage Backbones

Media and entertainment teams can deploy it where render nodes, editing systems and shared storage move large files continuously. It fits production fabrics where 400GbE spine capacity has become a bottleneck for ingest, rendering, collaboration and archive workflows.

Cloud Provider and Telecoms Fabric Nodes

Cloud and telecom operators can place the QFX5241-64OD in high-capacity spine, leaf or end-of-row roles for AI services, edge cloud and hosted infrastructure. It helps consolidate dense fabric links while preserving capacity for future workload growth.

Planning a Juniper QFX5241-64OD Deployment?

Our team can help design and deploy Juniper QFX5241-64OD fabrics for AI clusters, private cloud, finance, media and service-provider environments, with guidance on topology, port speeds, resilience and operational scale.
