Each week, SearchSDN takes to Twitter to see what users, including experts, analysts and editors, are saying about software-defined networking. By using Storify and searching hashtags, keywords and tweetups, we scour the social media site to see what users have to say about SDN, OpenFlow, network virtualization and more. This week, we looked to Twitter and got an earful from Tweeters about Cisco Live and Cisco onePK, as well as a lively discussion regarding SDN, hardware versus software and data center costs.

Best analogy so far: today's networks r like asking directions each intersection. #SDN OpenFlow resembles a GPS, computes end to end route— Michael Warrilow (@micwarg) June 26, 2013
After searching through tweets this week, we also stumbled across a discussion between Joe Onisick, technical marketing engineer and founder at Define the Cloud, and Jason Edelman, blogger and senior solutions architect based out of New York City. Both heated up the social networking site with this discussion focusing on the cost of hardware versus SDN.
@jonisick Aren't you glad virtual ports are free?— Jason Edelman (@jedelman8) June 26, 2013
@jedelman8 Which virtual ports are free? KVM, Xen, any others? That's also before you make them anything other than an L3 switch.— Joe Onisick (@jonisick) June 26, 2013
@jonisick Hmmm, Cisco 1000V.— Jason Edelman (@jedelman8) June 26, 2013
.@jedelman8 And no matter how whiz bang magic unicorn you make a virtual port it won't push a packet without a switch at cables end.— Joe Onisick (@jonisick) June 26, 2013
@jonisick BS. Plug the servers into a massive network of powerline adapters ;)— Jason Edelman (@jedelman8) June 26, 2013
@jedelman8 Sadly there is some startup with funding trying to pawn off server interconnect cabling with software as ToR replacement.— Joe Onisick (@jonisick) June 26, 2013
@jonisick ...and you move the extra cost from the hw to an expensive sw controller cluster... overall cost is pretty much the same.— Todd Craw (@toddmcraw) June 26, 2013
