The Mellanox SN4700 is a flagship Ethernet switch for data centre spine roles where high-capacity aggregation and simpler fabric growth are essential. With QSFP56 connectivity and hot-swappable PSUs, it supports demanding east-west traffic while helping keep the network resilient and easier to scale.

As compute, storage and east-west traffic continue to grow, infrastructure teams need fabric capacity that keeps aggregation simple while preserving headroom for the next wave of workloads.
The Mellanox SN4700 is built for spine, super-spine and high-performance leaf roles in 200/400GbE fabrics, giving teams a compact way to add faster uplinks where 100GbE aggregation has become too link-heavy.
With Spectrum-3 switching and 32-port 400GbE design in a 1U footprint, it helps reduce spine count and oversubscription, so expansion can happen without redesigning the network around larger tiers.
That translates into cleaner growth for data-centre operations and a fabric that is easier to scale, while supporting heavier render, analytics, AI and storage traffic with fewer moving parts.
For a closer look at the Mellanox SN4700, our team can help assess where it fits in your fabric and how it can simplify the next stage of expansion.
The Mellanox SN4700 is a high-speed networking switch for modern data center environments, designed to provide dense connectivity and platform-level performance for large-scale fabric deployments.
High-Density Port Architecture
The switch provides 64×QSFP56 ports to support dense leaf, spine, or aggregation connectivity in high-performance network fabrics.
High-Speed Forwarding Design
Its architecture is built to sustain 200G port operation for bandwidth-intensive east-west traffic patterns.
Scalable Switching Capacity
The platform delivers 25,600 Gbps of switching capacity to support large-scale traffic aggregation and fabric growth.
Data Center Fabric Role
The SN4700 is positioned as a networking switch for data center infrastructure where density, speed, and scalable interconnect matter.
Fabric-Oriented Deployment
The switch fits network architectures that require predictable interconnect behavior across multiple high-speed endpoints.
Platform Validation
Its published port configuration and switching capacity provide clear sizing inputs for design and capacity planning.
Architecture-Led Expansion
The dense 64-port design supports straightforward scaling as network demands increase.
If you are planning a high-density data center fabric, our team can help align the SN4700 to bandwidth, port-density, and scale requirements.
The Nvidia Mellanox SN4700 is a 400GbE switch for fast-growing spine fabrics and high-throughput aggregation tiers. It fits environments where east-west traffic is rising, oversubscription is becoming costly, and the network must support denser compute and storage without repeated redesign.
In data centres pushing beyond 100GbE aggregation, the SN4700 helps reduce spine count and simplify fabric growth. Teams use it when link pressure is rising and they need more headroom before the next layout change.
Media and entertainment platforms with large render farms, simulation clusters and generative-media pipelines generate constant east-west movement. The SN4700 supports these backbones when storage and GPU traffic must stay clear of network bottlenecks.
Healthcare environments running imaging, genomics and AI workloads need fabric capacity that keeps pace with new compute and storage tiers. The SN4700 gives those estates a 400GbE core for heavier dataset movement and steadier throughput.
Financial firms building denser analytics and market-data platforms need fewer, faster uplinks to keep cluster traffic moving cleanly. The SN4700 suits core fabric roles where bandwidth growth and operational simplicity both matter.
Software teams running large AI training, fine-tuning and shared engineering environments often outgrow 200GbE aggregation. The SN4700 supports those platforms when high-speed data pipelines and lower contention are needed for day-to-day development.
Our team can help design and deploy Mellanox SN4700 fabrics for data centres, AI clusters, research environments and high-bandwidth production estates, with practical support for sizing, resilience planning and deployment decisions.
