I recently wrote a tip that discussed some of what it takes to support VMotion. Lori MacVittie of F5 wrote a blog entry in which she took me to task for writing an article that had a section that she stated was "inaccurate and misleading". I have a lot of respect for Lori, but I found her comments to be bewildering and surprising.
In the section that Lori took objection to I mentioned Cisco. Lori determined that since I mentioned Cisco I was using them as a 'yardstick" for application delivery controllers. To make her point, she asked "When writing an article on the state of networking would you use Juniper or Extreme as your measuring stick for switches instead of Cisco?" I was bewildered by her question because I know that Lori knows that the role of an industry analyst is to analyze competing products and services based on their merit. If Juniper or Extreme did something particularly well, or particularly badly, I would definitely write about them. For example, if I thought that Extreme did a particularly good job of making network and port-level capabilities configurable at the individual VM level, I might write about that. I would not, however, expect that any IT professional reading the article would assume that I was implying that Extreme has the largest share of the switching market.
