2015 – Increased SDN Adoption; Combining Switch and Server Functions in One Platform Becomes Key in Network Virtualization

Last year, I wrote here on, "in 2014, we'll finally see signs that the inescapable commoditization of Data Center Top-of-Rack switches will begin to accelerate, and this segment of networking will finally be ready to follow in the footsteps of the server market." You can read the article here. Looking back,, I realized that I had underestimated how prevalent this would become. For example, the year is closing with Juniper announcing that they will support the OCP hardware.

So now that everyone has the same hardware, what differentiates is the software that runs the hardware. Last year, I had also predicted that "that 2014 will mark the beginning of a sea change in network operating systems for white-label hardware." The year is ending with this issue being the biggest factor in adoption of white-label hardware. Cisco suing Arista for software patent infringement is a prime example of complexity of the software and the amazing hold Cisco has over legacy networking.

Fast-forwarding to 2015, and I think the march of white-label hardware (or ‘brite-label' hardware, per Gartner's latest statements) will continue into the enterprise as well. The year 2015 will also see the rise of SDN applications of more server-style switch OS. The large enterprise customers and datacenters will be worried about patent infringement issues so switch OSs built from OPEN source software and server ecosystems will have an immediate appeal.

I think 2015 will also start seeing the trend of unifying overlay/underlay and making the network more relevant and valuable for new applications that help with application analytics, security, compliance and virtualized network services. The year 2014 ended for us with one of our customers, Lucera, building their entire HFT cloud (three datacenters in Chicago, NYC and London) using our network hypervisor on one of our server-switches for SDN switching and breaking five world records on the STAC M3 distributed database benchmark. Why does it matter for the SDN world? I think this datacenter design provides the blueprint for SDN in Wall Street that doesn't need a Cisco-like CLI. I will be looking at this article again at the end of 2015; SDN adoption will continue to increase and I will proudly link to this piece once I'll write my 2016 predictions.

Once again, how great is it to be a part of the virtualization and cloud industries? 2014 was another banner year, and we witnessed a number of fantastic technologies take shape and skyrocket. And I, along with many industry experts and executives, media
