NetApp today announced a predictable step in the transition of their corporate leadership, with Tom Georgens taking over as CEO and long-time Dan Warmenhoven planning retirement after a short stint as Executive Chairman. Today’s move follows Georgens’ promotion to President and COO in January of 2008, and is part of a remarkably smooth and clear transition of power for the enterprise storage company. NetApp founder, Dave Hitz, broke the news, chronicling the transition in his blog.
