The Fat Middle: Today’s Enterprise Storage Array

August 31, 2014 By Stephen 7 Comments

Ask any project manager if it's possible to deliver something that is fast, good, and cheap, and they'll laugh.

Is Storage the Killer App for Software-Defined Networking?

October 3, 2011 By Stephen 4 Comments

Update Happily I was able to record both my presentation and The Great Debate with Stu!
