CNET News.com reports that IBM showed off a prototype Cell-based blade server at CeBit today. The server ran visualization software illustrating a 3D-rendered animation of a beating heart that could be filtered to only show certain elements, such as blood vessels. This allows a researcher to rotate the image of the heart and observe it from any angle, or filter out elements such as blood or certain tissue to give a transparent view into the center of the heart. IBM is planning to launch the Cell blades commercially in the third quarter.  It's also not clear exactly what the performance increase will be compared to existing blade servers. However, the Cell chips in the system on display at CeBit were running at 2.4GHz. Bacher said the commercial unit would run at between 2.4GHz and 4GHz.
