About the NVIDIA Spectrum SN2900
The NVIDIA Spectrum SN2900 (part number SN2900-4S) delivers 48 × 25GbE ports with 8 × 100GbE uplink capacity, enabling 3.2 Tbps of switching throughput in a compact 1U form factor. Built on the NVIDIA Spectrum-1 ASIC, this high-performance Ethernet switch combines dense 25GbE access connectivity with substantial 100GbE spine uplinks, making it ideal for operators seeking predictable, low-latency fabric performance. Network engineers and infrastructure architects rely on the SN2900-4S to scale data center networks without compromising port density or operational simplicity.
NVIDIA Cumulus Linux provides carrier-grade routing, VRF isolation, ECMP load-balancing, and comprehensive ACL enforcement across BGP, OSPF, and static routing protocols. The switch supports VXLAN and EVPN overlays for seamless virtualization integration, while dual hot-swappable power supplies and field-replaceable fan modules reduce unplanned downtime. Redundant management interfaces, sFlow telemetry, and LACP aggregation ensure operational visibility and resilience in demanding environments. Cut-through and store-and-forward forwarding modes deliver 2.38 Bpps with sub-microsecond latency, critical for latency-sensitive applications.
Typical Enterprise Deployments
- High-frequency trading and financial services requiring ultra-low-latency interconnects between compute clusters and storage arrays
- Machine learning and GPU acceleration frameworks where dense 25GbE access ports connect training nodes to high-speed fabric uplinks
- Multi-tenant cloud environments leveraging VXLAN segmentation and QoS policies for tenant isolation and SLA enforcement
- Hyperscale data centers standardizing on open networking stacks for vendor flexibility and operational cost reduction
- HPC and scientific computing clusters needing reliable, deterministic packet delivery across large node counts
