Customer Shipments of Mellanox SN4000 Ethernet Switches Using Spectrum-3 12.8Tb/s Ethernet Switch ASIC

Up to 128 ports of 100GbE, 64 ports of 200GbE or 32 ports of 400GbE, and up to 200,000 NAT entries, and one million on-chip routes

Mellanox Technologies, Ltd. announced that customer shipments of SN4000 Ethernet switches have commenced.

SN4000 Series Ethernet switches

Mellanox Sn4000 Series

The SN4000 family is powered by the firm’s Spectrum-3 – a scalable, and flexible 12.8Tb/s Ethernet switch ASIC, which is optimized for cloud, Ethernet storage fabric, and AI interconnect applications. The platforms come in flexible form-factors supporting a combination of up to 32 ports of 400GbE, 64 ports of 200GbE and 128 ports of 100/50/25/10GbE. They complement the 200/400GbE SN3000 leaf switches to form an efficient and high bandwidth leaf/spine network.

Spectrum-3 supports scale, tunneling, and network virtualization capabilities with its FlexFlow packet processing technology and WJH (What Just Happened) based real-time telemetry. Spectrum-3 is for building massive, high performance layer-2 and layer-3 fabrics, for both virtualized and non-virtualized use cases.

Key highlights:

  • Up to 128 ports of 100GbE, 64 ports of 200GbE or 32 ports of 400GbE

  • Up to 200,000 NAT entries, and one million on-chip routes

  • Shared packet buffer to maximize burst absorption and deliver fair bandwidth sharing

  • RoCE-Ready one-click configuration with hardware-accelerated, end-to-end congestion management to simplify networking for storage, AI, and big data workloads

  • FlexFlow programmable pipeline which delivers network processing capabilities at an unprecedented scale

  • WJH based granular telemetry to simplify network operations and dramatically reduce mean time to issue resolution

  • Simultaneous NRZ and PAM4 port speeds allowing flexible configurations

  • Dual stack IPV4 and IPV6 protocol operation

  • Support for overlay protocols including EVPN, VXLAN-GPE, MPLS-over-GRE/UDP, NSH, NVGRE, MPLS/IPv6 based Segment routing and more

  • Flowlet-based adaptive routing maximizes performance and network utilization for layer-3 fabrics with high cross-sectional bandwidth

  • Support for customer-defined, on-switch, containerized micro-services with complete SDK access to host management, orchestration, and telemetry applications.

Spectrum-3 offers better performance, more advanced features, and easier management than any other 12.8 terabit switch,” said Amit Katz, VP, Ethernet switches, Mellanox. “Our VXLAN support features single-pass routing for more than 500,000 tunnels, making Spectrum-3 the best switch not only for cloud data centers, but for any networking deployment supporting virtualization, containers, or microservices.

Over the last several years, with the Spectrum and Spectrum-2 product lines, Mellanox has steadily grown its market share in the 100GbE top-of-rack Ethernet switch segment,” said Seamus Crehan, president, Crehan Research, Inc.As of the most recent reported quarter, Mellanox moved up to the fourth overall position worldwide in this segment, with over 7% market segment share. The introduction of these new Spectrum-3 based switches should enable additional growth for Mellanox in the emerging 200GbE and 400GbE segments.

Mellanox and Cumulus have been collaborating for over five years to help our data center customers build agile, high performance and highly-automated infrastructure using Linux,” said Josh Leslie, CEO, Cumulus Networks. “Spectrum-3 enables a feature-rich leaf/spine network architecture able to achieve massive scale, at twice the performance as was previously possible, making the combination of Cumulus Linux and Spectrum-3 an important part of our product portfolio.

Spectrum-3 is the latest addition to a portfolio of software and hardware products based on Ethernet Cloud Fabric (ECF) technology and is backward-compatible with earlier Spectrum models at an SDK level.

Like other switches in the Spectrum family, Spectrum-3 is ONIE bootable and supports a choice of open Network OSs (NOS) including the company’s Onyx, DENT, SONiC, and Cumulus. Customers can enjoy performance and scale while continuing to use a consistent software model.
