The Mellanox SN3700 delivers high-bandwidth spine connectivity for enterprise data centres where 100GbE fabrics need more headroom. Its 200GbE architecture and low-latency Spectrum design help AI, storage and scale-out environments grow without excessive oversubscription.
Guide price: Price range: £14,995.00 through £22,995.00 Ex. VAT
As east-west traffic grows and storage movement becomes more demanding, fabrics need a faster path that preserves headroom without adding unnecessary complexity.
The Mellanox SN3700 is a Nvidia switch for spine deployments in AI, storage and scale-out environments. It is built around 32×QSFP56 ports at 200G, giving infrastructure teams a clean upgrade path when 100GbE fabrics are no longer enough.
With 6,400Gbps of switching capacity, the platform fits roles where aggregate throughput and low-latency transport matter more than adding layers of infrastructure. It supports a fabric design that can take on heavier uplinks and keep traffic moving between compute and storage domains.
That makes it a practical choice for environments where cluster density, parallel jobs and large data sets keep pushing the network harder. The result is a spine layer that can absorb growth with less oversubscription pressure and a clearer path for future expansion.
Our team can help you assess the Mellanox SN3700 against your current fabric design and deployment plans.
The Mellanox SN3700 is a spine switching platform for modern data center fabrics, designed to support high-bandwidth connectivity and operational consistency in large-scale network environments.
Spine Switching Role
The platform is positioned for spine deployment, providing the aggregation layer for data center fabric architectures.
200G Port Scalability
It supports up to 200G port speed, enabling high-throughput fabric design for bandwidth-intensive network environments.
Fabric Interconnect Design
Its architecture is suited to connecting large numbers of leaf and endpoint connections through a centralized spine layer.
Platform Consistency
The switch model is built for repeatable deployment across new and refurbished units within the same product family.
Network Operating System Choice
The platform supports Onyx and Cumulus Linux, allowing integration into different operational and automation models.
Lifecycle Flexibility
Support for multiple operating systems helps align the switch with existing network management and deployment practices.
Fabric Administration
The operating system options provide a basis for consistent configuration and ongoing administration in spine environments.
If you are planning a spine fabric with high-speed aggregation requirements, our team can help align the SN3700 with your operating model and network architecture.
The Nvidia Mellanox SN3700 is a 200GbE switch for high-bandwidth data centre fabrics where 100GbE leaf or spine layers are starting to constrain AI, storage and east-west traffic.
In dense data centres, the SN3700 fits leaf or spine layers carrying GPU clusters, storage arrays and scale-out compute. Teams use it when 100GbE no longer leaves enough headroom and oversubscription is affecting day-to-day performance.
Media and entertainment sites with large render farms and simulation pipelines need faster fabric tiers to keep assets moving between nodes and storage. The SN3700 helps reduce waiting time without forcing an immediate move to 400GbE.
Healthcare research and imaging estates often run parallel analysis alongside heavy dataset movement, which can overwhelm 100GbE rack fabrics. The SN3700 supports these clusters when compute and storage traffic must keep flowing reliably.
In finance, the SN3700 suits advanced analytics, quant modelling and fraud-analysis platforms where bursty compute demand can queue traffic behind the fabric. It gives cluster nodes and storage more bandwidth headroom for sustained throughput.
Software development teams testing large AI or scale-out platforms need a 200GbE tier that reflects production demands before moving to higher speeds. The SN3700 helps validate training and data flows without bottlenecks from older fabrics.
Our team can help design and deploy Mellanox SN3700 fabrics for data centres, media, healthcare, finance and software environments, with practical guidance on sizing, traffic patterns, resilience and operational fit.
