通过经济高效的开放以太网优化利用率和效率

基于 NVIDIA® Spectrum®-3 的 SN4000 是一款开放以太网交换机,它将行业领先的云功能与突破性的性能相结合,以支持现代横向扩展的分布式数据中心应用程序。SN4000 支持 1GbE 到 400GbE 的各种速度,非常适合在新建和扩容场景下构建大型第 2 层、第 3 层和虚拟化网络结构。


Spectrum 网络优势

NVIDIA Mellanox What Just Happened(故障快照)

可视化

NVIDIA Spectrum SN4000 交换机通过 NVIDIA What Just Happened®(故障快照)支持详细的上下文相关的遥测数据。故障快照可在问题发生后,立即提供“时间”、“内容”、“人员”、“地点”和“原因”问题的答案,从而大大缩短了解决问题的平均时间。Spectrum 交换机实施硬件加速的直方图跟踪,并以亚微秒的粒度汇总队列深度。硬件加速的直方图避免了简单水印和基于阈值的方法中常见的误报。


Spectrum 交换机提供强大的高带宽

性能

NVIDIA Spectrum SN4000 交换机具有全共享和整体式数据包缓存架构。这种出色的缓存架构提供公平、可预测的高性能数据路径,这对于横向扩展软件定义的存储和现代多租户云部署至关重要。Spectrum 交换机为通过融合以太网进行远程直接内存访问 (RoCE) 和利用 GPUDdirect® 的机器学习应用程序提供强大的高带宽和低延迟数据路径。


SN4000 交换机支持一流的虚拟可扩展局域网 (VXLAN)

规模

NVIDIA Spectrum SN4000 交换机支持一流的虚拟可扩展局域网 (VXLAN),支持 10 倍以上的隧道和隧道端点。其 51.2 万个共享转发条目可灵活用于访问控制列表 (ACL)、最长前缀匹配 (LPM) 路由、主机路由、MAC 表以及等价多路径 (ECMP) 和隧道应用程序。

NVIDIA® Spectrum™ SN4000 series switches are the 4th generation of Spectrum switches, purpose-built for leaf/spine/super-spine datacenter applications.Allowing maximum flexibility, SN4000 series provides port speeds spanning from 1GbE to 400GbE, with 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 SN4000 series is ideal for building wire-speed and cloud-scale layer-2 and layer-3 networks. The SN4000 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.


Network Disaggregation: NVIDIA 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 re-gaining control of the network, and optimizing utilization, efficiency and overall return on investment. 

Open Ethernet adopts the same principles as standard open solutions for servers and storage, and applies them to the world of networking infrastructure. It encourages an ecosystem of open source, standard network solutions. 

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, NVIDIA SN4000 series allows you to pick and choose the right components for your data center.


NVIDIA SN4000 Series
SN4000 series platforms are based on the high-performance Spectrum-3 ASIC with a bidirectional switching capacity of 12.8Tbps. SN4000 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 leaf and fixed configuration spines. SN4000 series provides full wire speed, cut through-mode latency, on-chip fully-shared 64MB 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 SN4000 series is capable of addressing today’s data center’s complex networking requirements.


Platform Software Options
SN4000 series platforms are available out of the factoryin three different flavors:
       > Pre-installed with NVIDIA Cumulus Linux, a revolutionary operating system, taking the Linux user experience from servers to switches and providing a rich routing functionality for large scale applications.
       > Pre-installed with NVIDIA Onyx™, a home-grown operating system utilizing common networking user experiences and an industry standard CLI.
       > Bare metal including ONIE image, installable with any ONIE-mounted OS. ONIE-based platforms utilize the advantages of Open Networking and the Spectrum-3 ASIC capabilities.


High Availability
SN4000 series switches are designed with the followingsoftware and hardware
features for high availability:
      > 1+1 hot-swappable power supplies and N+1 hot-swappable fans
      > Color-coded PSUs and fans
      > Up to 128X 100/50/25/10/1GbE, 64X 200GbE or 32X 400GbE
      > Multi-chassis LAG for active/active L2 multipathing
      > 128-way ECMP routing for load balancing and redundancy
