Hopefully this post will help clear up some the misconceptions out there. The following is an excerpt from the paper entitled “Exadata Smart Flash Cache...

Debunking More Netezza FUD About Exadata
A reader recently left a comment for which my reply was longer than I’d like to leave for a comment so I’m answering it in detail with this blog post. Gabramel writes: Greg, Nice article.

Making the Most of Oracle Exadata – A Technical Review
Over the past few weeks several people have asked me about an Exadata article entitled “Making the Most of Oracle Exadata” by Marc Fielding of Pythian.

Partway Researched With A Chance Of FUD
I tend to keep the content of this blog fairly technical and engineering focused, but every now and then I have to venture off and do an editorial post. Recently some of the ParAccel management decided to fire up the FUD machine on the ParAccel blog and take aim at Oracle’s Exadata making the...
