Gartner Magic Quadrant for Enterprise Servers, 2004
“IBM continues to executewell on its pSeries strategy,
maintaining the top positionin this year's update.
pSeries execution has been strong throughout 2004, and offers high-end levels of performance that few other
server vendors can match.
This assessment is also based on the Power4+ technology, so with the new Power5-based servers getting ready to ship in volume, their opportunities for quadrant leadership should remain strong.”

IBM eServer Series: the emerging UNIX leaderTrends forecast by Gartner*
� Through 2008, the server operating system shakeout will continue and the server microprocessor shakeout will accelerate
� Only three server OSs predicted to grow share —Microsoft Windows, Linux and AIX®
� Only three server microprocessor architectures predicted to grow share—IA-32, IPF and POWER
� AIX will approach or overtake Solaris as the #1 UNIX operating system
