PRODUCT BRIEF

†

Spectrum-based 32-port 100GbE Open Ethernet Platform

Mellanox SN2700 provides the most predictable, highest density 100GbE
switching platform for the growing demands of today’s data centers.

The SN2700 switch is an ONIE (Open Network Install Environment) based platform that supports a
multitude of operating systems, as well as utilizing the advantages of Open Ethernet and the capabilities
of the Mellanox Spectrum

The SN2700 has three modes of operation:

– Preinstalled with Mellanox Onyx™ (successor to MLNX-OS Ethernet), a home-grown operating system

utilizing common networking user experiences and industry standard CLI.

– Preinstalled with 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.

– Provided with a bare ONIE image ready to be installed with the aforementioned or other ONIE-based

operating systems.

The SN2700 switch is an ideal spine and top-of-rack (ToR) solution, allowing maximum exibility, with

port speeds spanning from 10Gb/s to 100Gb/s per port and port density that enables full rack connectivity
to any server at any speed. The uplink ports allow a variety of blocking ratios that suit any application
requirement.

Powered by the Spectrum ASIC and packed with 32 ports running at 100GbE, the SN2700 carries a
whopping throughput of 6.4Tb/s with a landmark 4.76Bpps processing capacity in a compact 1RU form
factor.

Keeping with the Mellanox tradition of setting performance record switch systems, the SN2700
introduces the world’s lowest latency for a 100GbE switching and routing element, and does so while
having the lowest power consumption in the market. With the SN2700, the use of 25, 40, 50 and 100GbE
in large scale is enabled without changing power infrastructure facilities.

The SN2700 is part of Mellanox’s complete end-to-end solution which provides 10GbE through 100GbE
interconnectivity within the data center. Other devices in this solution include the ConnectX
of network interface cards, and LinkX
Mellanox NEO® a management application that relieves some of the major obstacles when deploying a

network. NEO enables a fully certied and interoperable design, speeds up time to service and eventually

speeds up ROI.

The SN2700 introduces superior hardware capabilities including

dynamic exible shared buffers and predictable wire speed

performance with no packet loss for any packet size.

While Spectrum provides the thrust and acceleration that powers
the SN2700, the system gets yet another angle of capabilities while
running with a powerful x86-based processor, which allows this
system to not only be the highest performing switch fabric element,
but also gives the ability to incorporate a Linux running server into the
