Somehow they neglected to mention Sun is being sued for violating NetApp’s long standing patents on storage technology, which could obviously be a huge hurdle for them entering that market.
If you go back and read previous article’s on that, Sun was most likely bating NetApp into that lawsuit. NetApp probably can’t win, and Sun will get enormous goodwill in the Open Source community. I think Jonathon Schwartz was not displeased when NetApp filed that suit.
