The NVIDIA® Spectrum SN3000 series switches are based on the 2nd generation of Spectrum switches, purpose-built for leaf/spine/super-spine data center applications. Allowing maximum flexibility, the SN3000 series provides port speeds spanning from 1GbE to 400GbE, and a port density that enables full rack connectivity to any server at any speed. In addition, the uplink ports allow a variety of blocking ratios to suit any application requirement.
The SN3000 series is ideal for building cloud-scale layer-2 and layer-3 networks. The SN3000 platforms deliver high performance, consistent low latency along with support for advanced software defined networking features, making it the ideal choice for web scale IT, cloud, hyperconverged storage and data analytics applications.
SN3000 series platforms are based on the high-performance Spectrum-2 ASIC with a bidirectional switching capacity of 6.4Tb/s. SN3000 platforms are available in a range of configurations, each delivering high performance combined with feature-rich layer 2 and layer 3 forwarding, ideally suited for both top-of-rack (ToR) leaf and fixed configuration spines.
SN3000 series provides full wire speed, cut through-mode latency, on-chip fully-shared 42MB packet buffering, and flexible port use in addition to advanced capabilities. Combining a wide range of innovations in the area of programmability, telemetry, and tunneling with industry leading performance, NVIDIA SN3000 series is capable of addressing today’s data center’s complex networking requirements.
Performance
• Fully shared packet buffer provides a fair, predictable and high bandwidth data path
• Consistent and low cut-through latency
• Robust RoCE transport to power NVMe over fabric and Machine Learning applications that leverage NVIDIA GPUDirect
• Best-in-class VXLAN scale 10X more tunnels and tunnel endpoints than others
• 512K shared forwarding entries flexibly shared across ACL, LPM routes, host routes, MAC, ECMP and tunnel applications
Network Disaggregation: Open Ethernet
Open Ethernet breaks the paradigm of traditional switch systems, eliminating vendor lock-in. Instead of forcing network operators to use the specific software that is provided by the switch vendor, open Ethernet offers the flexibility to use a choice of operating systems on top of Ethernet switches, thereby regaining control of the network, and optimizing utilization, efficiency and overall return on investment.
Encouraging an ecosystem of open source, standard network solutions, open Ethernet adopts the same principles as standard open solutions for servers and storage, and applies them to the world of networking infrastructure. These solutions can then be easily deployed into the modern data center across network equipment that eases management and ensures full interoperability.
With a range of system form factors, and a rich software ecosystem, SN3000 series allows you to pick and choose the right components for your data center.
