TFD Bonus 3 — Peter Wohlers of Force10 Presents to Tech Field Day San Jose 09/16/2010

On September 16 & 17, Pushers  Greg Ferro and  Ethan Banks attended the Tech Field Day event in San Jose, California.  This TFD bonus edition podcast is the third in a series of edited vendor presentations that is releasing over the next few weeks.

Notes on the audio:  the presentations were recorded with a conference table microphone so as to pick up both the presenters and the delegates as there was back and forth dialog from time to time.  In post-edit, noise filtering and leveling was applied to make the quality as listenable as possible.  That said, the audio is not perfect.  We know.  Audio quality is important to us, too, and we promise we’re trying to make it as good as we can.

What You’ll Hear

Peter Wohlers, Systems Engineer with Force10 Networks, presents to the Tech Field Day delegation about the Force10 product line  ”speeds and feeds”.  The conversation gets geeky with a lot of back and forth between Peter and the delegates.  In the conversation, you’ll hear Greg Ferro,  Ivan Pepelnjak, and Brandon Carroll from the TFD delegation, as well as Stephen Garrison, Vice President of Marketing for Force10.
