The Ethernet Switching Landscape – Part 08 – SDN & OpenFlow

This is one of a multi-part series on the Ethernet switching landscape I wrote to support a 2-hour presentation I made at Interop Las Vegas 2014. Part 1 of this written series appeared on NetworkComputing.com. Search for the rest of this series.

Ethernet switches have been a focal point of software defined networking. As some early SDN use-cases have centered on the data center, this makes sense.

Thinking Through A Mellanox Dual-Tier Fixed Switch 10G + 40G Fabric Design

When preparing for “The Ethernet Switching Landscape” presentation at Interop, I did quite a bit of reading through vendor marketing literature and documentation. One proposed fabric design by Mellanox stuck in my brain, because I was having a hard time mapping the numbers in their whitepaper to what the reality would look like. Here’s the slide I built around a section in the Mellanox whitepaper.

The point of this design was to demonstrate how to scale out a fabric supporting a large number of 10GbE access ports using fixed configuration Mellanox switches.
