The new Sun Blade 6000 can handle SPARC, AMD, and Intel Xeon based server modules. Additionally, to differentiate itself from competitors, Sun is using an industry standard I/O architecture, PCI-Express (similar to the Blade 8000). Furthermore, standard I/O reduces costs for customers versus proprietary I/O solutions, which can cost more than the chassis or the server modules. For full details from Sun, click here. The Register has an article with minor comparison of the Sun Blade 6000 to IBM and HP products. (This is the same blade servers that was spotted on 5/22.)
